Take a look around your home. | 0:00:03 | 0:00:05 | |
Can you be sure that every appliance is safe? | 0:00:08 | 0:00:11 | |
Is everything a company tells you about a product true? | 0:00:13 | 0:00:16 | |
And are you getting the best value for your money? | 0:00:18 | 0:00:20 | |
With the help of the country's top experts, | 0:00:22 | 0:00:24 | |
we're going to see what it takes to test the household products | 0:00:24 | 0:00:28 | |
we use every day. | 0:00:28 | 0:00:30 | |
We'll discover how they're pushed to their limits. | 0:00:33 | 0:00:36 | |
We'll put the makers' claims on trial. | 0:00:37 | 0:00:40 | |
And show you how to make your money go further. | 0:00:41 | 0:00:45 | |
You'll find these products in any ordinary house. | 0:00:45 | 0:00:48 | |
But THIS is no ordinary house. | 0:00:48 | 0:00:51 | |
And no ordinary street. | 0:00:51 | 0:00:53 | |
This is the Watchdog Test House. | 0:00:53 | 0:00:56 | |
Hello. We're deep inside one of Britain's leading science centres. | 0:01:01 | 0:01:06 | |
Here at the Building Research Establishment, some of the products | 0:01:06 | 0:01:10 | |
and materials that we use every day are put to the test | 0:01:10 | 0:01:14 | |
to make sure that they are safe, | 0:01:14 | 0:01:16 | |
environmentally friendly and that they don't fall apart. | 0:01:16 | 0:01:19 | |
Coming up on today's programme: | 0:01:20 | 0:01:22 | |
Safe as houses? | 0:01:22 | 0:01:24 | |
What you need to know if you have one of these locks. | 0:01:24 | 0:01:27 | |
As you can see, it looks like a really secure door, | 0:01:27 | 0:01:29 | |
but what I'm going to demonstrate is a lock-snapping method. | 0:01:29 | 0:01:33 | |
Easy as that! | 0:01:34 | 0:01:36 | |
Beating the burglars, | 0:01:36 | 0:01:37 | |
the industry experts taking on the most determined housebreakers. | 0:01:37 | 0:01:42 | |
These headphones claim to cancel out unwanted background noise. | 0:01:42 | 0:01:46 | |
But how will they cope with this? | 0:01:46 | 0:01:48 | |
LOUD DRILL | 0:01:48 | 0:01:50 | |
Plus, quantum leaps in design, exhaustive testing, | 0:01:50 | 0:01:53 | |
and pressure from Watchdog. | 0:01:53 | 0:01:55 | |
I'll let you know what happens to this story. | 0:01:56 | 0:01:59 | |
How it all led to a safer microwave in your kitchen. | 0:01:59 | 0:02:02 | |
Let's start with the front door. | 0:02:08 | 0:02:10 | |
There are more than 180,000 burglaries across the UK every year, | 0:02:10 | 0:02:15 | |
so it's vital that all doors and locks are tested properly | 0:02:15 | 0:02:19 | |
before they're sold. | 0:02:19 | 0:02:20 | |
The tests are rigorous. | 0:02:20 | 0:02:22 | |
But the criminals are becoming ever-more cunning. | 0:02:22 | 0:02:25 | |
And one of the latest challenges for the security industry | 0:02:25 | 0:02:28 | |
is lock-snapping. | 0:02:28 | 0:02:30 | |
It's fast become a nationwide concern. | 0:02:30 | 0:02:33 | |
A certain type of lock called a Euro cylinder | 0:02:33 | 0:02:36 | |
fitted to millions of UPVC doors and windows up and down the country | 0:02:36 | 0:02:40 | |
that can be broken by burglars in seconds. | 0:02:40 | 0:02:43 | |
A phenomenon known as lock snapping. | 0:02:43 | 0:02:46 | |
Alan Boylan from Leeds was a recent victim. | 0:02:46 | 0:02:48 | |
Got up when the alarm went off. | 0:02:48 | 0:02:50 | |
I assumed that I'd left my lights on and gone to bed leaving them on. | 0:02:50 | 0:02:54 | |
It were only when I actually got to the kitchen window | 0:02:54 | 0:02:57 | |
I realised that my conservatory door was wide open. | 0:02:57 | 0:03:00 | |
As I've opened the inner door to go to the conservatory door | 0:03:00 | 0:03:03 | |
to see why it was left open, handle fell off in my hand | 0:03:03 | 0:03:07 | |
and I found that the lock had been damaged on the door. | 0:03:07 | 0:03:11 | |
It was then that Alan realised intruders had been in his home. | 0:03:11 | 0:03:15 | |
They'd managed to take his laptop, games console | 0:03:15 | 0:03:17 | |
and even his car from the driveway, all without waking him. | 0:03:17 | 0:03:21 | |
That's because the lock snapping technique is quiet, quick | 0:03:21 | 0:03:24 | |
and all-too easy for burglars in the know. | 0:03:24 | 0:03:27 | |
Since the burglary, it's affected my family in a bad way, | 0:03:27 | 0:03:31 | |
especially my wife. | 0:03:31 | 0:03:33 | |
She can't sleep at night now. | 0:03:33 | 0:03:34 | |
I have to come home on my break to make sure everything's all right, | 0:03:34 | 0:03:38 | |
do a full check of the house then go back to work. | 0:03:38 | 0:03:40 | |
I'd advise anyone who's going to buy a house or who's got these | 0:03:40 | 0:03:44 | |
locks on the door to remove them and put high security ones in. | 0:03:44 | 0:03:49 | |
So, what is lock snapping? | 0:03:49 | 0:03:51 | |
Neil Goldup works for Community Action and Support against Crime, | 0:03:51 | 0:03:54 | |
or CASAC, a local charity dedicated to improving home security | 0:03:54 | 0:03:58 | |
in West Yorkshire. | 0:03:58 | 0:03:59 | |
Today, his company is being paid to replace Alan's locks. | 0:03:59 | 0:04:02 | |
This is a broken Euro cylinder, | 0:04:02 | 0:04:04 | |
exactly the same type which would have been fitted to this property. | 0:04:04 | 0:04:08 | |
The burglars have found a technique, | 0:04:08 | 0:04:10 | |
it's very quick, quiet and very easy to get through these, | 0:04:10 | 0:04:13 | |
and these types of lock actually control the mechanism in the door. | 0:04:13 | 0:04:16 | |
Once they bypass this and get access to the locking mechanism, | 0:04:16 | 0:04:19 | |
it's quite easy for them to do. | 0:04:19 | 0:04:21 | |
To show just how vulnerable these locks can be, | 0:04:21 | 0:04:24 | |
we'll put it to the test. | 0:04:24 | 0:04:25 | |
Neil's told us he can get through a locked door in a matter of seconds. | 0:04:25 | 0:04:29 | |
And he's going to prove it. | 0:04:29 | 0:04:30 | |
As you can see, it looks like a really secure door, | 0:04:30 | 0:04:33 | |
but I'm going to demonstrate a lock- snapping method. So, here I go. | 0:04:33 | 0:04:37 | |
We can't show you exactly what Neil's doing, but what we can say | 0:04:37 | 0:04:41 | |
is that it takes him just eight seconds to break through the door. | 0:04:41 | 0:04:45 | |
As easy as that! | 0:04:45 | 0:04:46 | |
OK, so it does involve a certain level of skill and inside knowledge, | 0:04:46 | 0:04:50 | |
but with the issue of lock-snapping becoming a nationwide problem, | 0:04:50 | 0:04:54 | |
it was clear something needed to be done. | 0:04:54 | 0:04:56 | |
So, in 2012, a new design of lock was released onto the market. | 0:04:56 | 0:05:01 | |
Because of all the hard work CASAC have done over the past seven years | 0:05:01 | 0:05:05 | |
around this type of attack with police, and British Standards, | 0:05:05 | 0:05:08 | |
new standards have come out and manufacturers have started to develop | 0:05:08 | 0:05:12 | |
cylinders and products to withstand this type of attack. | 0:05:12 | 0:05:16 | |
So, what is this new lock and how rigorously are some doors | 0:05:16 | 0:05:20 | |
and their locks now tested before they come onto the market? | 0:05:20 | 0:05:23 | |
Later, we head to the British Standards Institution to find out. | 0:05:23 | 0:05:28 | |
And we'll also be telling you what YOU can do | 0:05:28 | 0:05:31 | |
to make sure your home is SAFE. | 0:05:31 | 0:05:33 | |
Now, headphones, noise cancelling headphones. | 0:05:38 | 0:05:41 | |
They promise to improve your entire listening experience. | 0:05:41 | 0:05:45 | |
How? | 0:05:45 | 0:05:46 | |
By actively drowning out external sounds, | 0:05:46 | 0:05:49 | |
leaving you in your own private cocoon. | 0:05:49 | 0:05:52 | |
Nice promise, but how good are they? | 0:05:52 | 0:05:54 | |
Well, Sophie, let's find out. | 0:05:57 | 0:05:59 | |
If they live up to their claim, you'll hear your favourite track... | 0:06:00 | 0:06:04 | |
..and very little else. | 0:06:05 | 0:06:08 | |
Some headphones simply work to block the noise coming in to our ears, | 0:06:08 | 0:06:13 | |
but these headphones here go a step further and make use | 0:06:13 | 0:06:16 | |
of some clever electronic systems to actively cancel that noise out. | 0:06:16 | 0:06:21 | |
Sounds good in theory, | 0:06:21 | 0:06:23 | |
I'm interested to see how they work in practice. | 0:06:23 | 0:06:26 | |
Time to put them to the test. | 0:06:26 | 0:06:28 | |
We're going to look at three sets of headphones | 0:06:28 | 0:06:31 | |
bought from the UK's three top online retailers. | 0:06:31 | 0:06:34 | |
The cheapest we could find, the snappily-named JVC HA-NC80, | 0:06:34 | 0:06:39 | |
for £30. | 0:06:39 | 0:06:40 | |
A mid range set, the AKG K490 NC at £150. | 0:06:43 | 0:06:49 | |
And top of the range set, the Sennheiser MM550-X | 0:06:50 | 0:06:54 | |
costing a whopping £350. | 0:06:54 | 0:06:57 | |
They all claim to be able to actively cut out background noise, | 0:06:59 | 0:07:02 | |
but how well do they actually do the job? | 0:07:02 | 0:07:04 | |
To find out, we've gathered together some expert ears | 0:07:05 | 0:07:08 | |
to help put them through their paces. | 0:07:08 | 0:07:10 | |
Andrew is a music reviewer for Classic Music magazine. | 0:07:12 | 0:07:15 | |
Yeah, I like the idea of noise cancelling. | 0:07:15 | 0:07:17 | |
In a city like London, there's so much noise around - | 0:07:17 | 0:07:20 | |
the traffic and buses and sirens constantly. | 0:07:20 | 0:07:23 | |
Paul is a second year saxophone student | 0:07:25 | 0:07:27 | |
at the London School of Contemporary Music. | 0:07:27 | 0:07:29 | |
I'm looking for a good set of noise cancelling headphones. | 0:07:29 | 0:07:32 | |
And John is a lecturer in electronic musical composition, | 0:07:32 | 0:07:36 | |
amongst other things. | 0:07:36 | 0:07:37 | |
I teach experimental music and sonic art. | 0:07:37 | 0:07:40 | |
I'm concerned about everyday listening and sound quality a lot. | 0:07:40 | 0:07:44 | |
For headphones, I look for a really good level of noise reduction. | 0:07:44 | 0:07:48 | |
So, let's get started. | 0:07:48 | 0:07:49 | |
We ask the experts to sit in a cafe near a busy street. | 0:07:49 | 0:07:52 | |
So, how do the headphones perform | 0:07:52 | 0:07:54 | |
when forced to compete with the incessant din of traffic? | 0:07:54 | 0:07:58 | |
This is what the road sounds like | 0:07:58 | 0:08:00 | |
without the noise cancelling feature turned on. | 0:08:00 | 0:08:03 | |
HUM OF TRAFFIC | 0:08:03 | 0:08:04 | |
But once it's activated, it sounds like this. | 0:08:04 | 0:08:07 | |
QUIET PURR | 0:08:07 | 0:08:10 | |
So, our volunteers will try each headphone in turn, | 0:08:10 | 0:08:13 | |
listening to the same track at the same volume on the same device. | 0:08:13 | 0:08:17 | |
It's Rachmaninov Piano concerto number 3 for our classical | 0:08:18 | 0:08:22 | |
music reviewer, Andrew. | 0:08:22 | 0:08:24 | |
MUSIC PLAYS | 0:08:24 | 0:08:26 | |
Some Kraftwerk for our electronica don. | 0:08:26 | 0:08:29 | |
ELECTRONICA MUSIC | 0:08:29 | 0:08:31 | |
And a timeless bit of Kool and the Gang for our student. | 0:08:31 | 0:08:34 | |
# Jungle boogie... # | 0:08:34 | 0:08:36 | |
They'll mark each set of headphones out of five for sound quality | 0:08:36 | 0:08:40 | |
and out of five for how well they cancel out the sound of the road. | 0:08:40 | 0:08:43 | |
For each set, a total of 30 points up for grabs. | 0:08:43 | 0:08:46 | |
I thought the JVC headphones were the most disappointing, definitely. | 0:08:46 | 0:08:50 | |
JVCs were the worst for sound cancelling. | 0:08:50 | 0:08:53 | |
By far the worst performer on this part of the test was indeed | 0:08:53 | 0:08:56 | |
the cheapest product, the JVC HA-NC80. | 0:08:56 | 0:08:58 | |
They scored just 11 out of 30. | 0:09:01 | 0:09:03 | |
Perhaps more of a surprise was the headphones in second place, | 0:09:03 | 0:09:06 | |
top of the range Seinnheisers. | 0:09:06 | 0:09:08 | |
Although they did well on noise cancelling ability, | 0:09:08 | 0:09:11 | |
poor performance on sound quality let them down, | 0:09:11 | 0:09:14 | |
giving them a score of 20½ out of 30. | 0:09:14 | 0:09:17 | |
The Seinnheisers have an extremely marked noise cancelling function. | 0:09:17 | 0:09:21 | |
You really know when it's kicked in and when it's switched off. | 0:09:21 | 0:09:25 | |
But for me that has a slightly detrimental effect to the | 0:09:25 | 0:09:28 | |
actual sound of the music. | 0:09:28 | 0:09:30 | |
Which brings us to our winner in this part of the test, | 0:09:30 | 0:09:32 | |
our mid-range product, the AKG. | 0:09:32 | 0:09:34 | |
The AKG were by far the best, the most effective noise reduction. | 0:09:36 | 0:09:39 | |
Overall, a very impressive sound. | 0:09:39 | 0:09:42 | |
At £150, they cost £200 less than the most expensive product in our test. | 0:09:42 | 0:09:48 | |
And yet they scored 13 out of a possible 15 for sound quality | 0:09:48 | 0:09:52 | |
and 12½ out of 15 for noise cancelling. | 0:09:52 | 0:09:55 | |
A grand total of 25½ out of 30. | 0:09:55 | 0:09:58 | |
So, that's part one of the test. | 0:09:58 | 0:10:00 | |
How will they perform when we give them something else to deal with? | 0:10:00 | 0:10:04 | |
DRILL ROARS | 0:10:04 | 0:10:05 | |
Find out later. | 0:10:05 | 0:10:06 | |
MICROWAVE BEEPS | 0:10:13 | 0:10:15 | |
It's not often a product comes along that revolutionises the way we live. | 0:10:15 | 0:10:19 | |
The first counter-top microwave was produced in 1967 | 0:10:19 | 0:10:23 | |
and, by the mid-'80s, one in four homes had one. | 0:10:23 | 0:10:27 | |
But as demand grew, prices dropped and for some models, | 0:10:27 | 0:10:30 | |
that led to a fall in standards and serious safety issues. | 0:10:30 | 0:10:35 | |
A good thing Watchdog was around to expose them. | 0:10:35 | 0:10:37 | |
Here's Lynn Faulds Wood. | 0:10:37 | 0:10:39 | |
Welcome to Watchdog. | 0:10:42 | 0:10:43 | |
In tonight's programme, all these people have written to us. | 0:10:43 | 0:10:48 | |
'It's microwave popcorn.' | 0:10:48 | 0:10:50 | |
From small problems... | 0:10:50 | 0:10:52 | |
'Steam! | 0:10:52 | 0:10:53 | |
'That's scalding hot and could burn small hands | 0:10:53 | 0:10:56 | |
'that try to take it out of the microwave.' | 0:10:56 | 0:10:58 | |
..to serious health worries. | 0:10:58 | 0:11:01 | |
'Nowhere do the standards tell manufacturers | 0:11:01 | 0:11:03 | |
'they should take a thermometer | 0:11:03 | 0:11:05 | |
'and check that they are actually killing the bugs in their ovens.' | 0:11:05 | 0:11:09 | |
Over the years, the microwave oven has had plenty of reasons | 0:11:09 | 0:11:12 | |
to feature on Watchdog. | 0:11:12 | 0:11:15 | |
But that certainly hasn't put us off buying them. | 0:11:15 | 0:11:17 | |
Today, 95% of us have a microwave oven in our home. | 0:11:19 | 0:11:23 | |
And for people with busy lives they are a great invention. | 0:11:23 | 0:11:27 | |
So, it's amazing to think the ability to cook using microwaves | 0:11:27 | 0:11:31 | |
was a discovery that happened completely by chance. | 0:11:31 | 0:11:35 | |
In 1946, an American engineer, Percy Spencer of Raytheon, | 0:11:36 | 0:11:41 | |
was testing radar technology when he noticed the microwave radiation | 0:11:41 | 0:11:45 | |
coming from the device had melted the chocolate in his pocket. | 0:11:45 | 0:11:50 | |
He'd discovered that low-density microwave energy | 0:11:50 | 0:11:53 | |
could quickly cook food. | 0:11:53 | 0:11:55 | |
The way microwaves cook food is as soon as it touches | 0:11:55 | 0:11:59 | |
something organic such as food, | 0:11:59 | 0:12:02 | |
it will start vibrating the molecules in that food, | 0:12:02 | 0:12:05 | |
they cause friction and then cause heat | 0:12:05 | 0:12:09 | |
and it's that process that cooks the food. | 0:12:09 | 0:12:11 | |
-ARCHIVE: -Hamburgers perfectly done in 15 seconds. | 0:12:11 | 0:12:14 | |
By 1947, the Raytheon company had introduced the world | 0:12:14 | 0:12:19 | |
to the first microwave oven. | 0:12:19 | 0:12:21 | |
Although it did cost thousands of dollars and weigh 340 kilos. | 0:12:21 | 0:12:27 | |
It wasn't until 1967, after 20 years of continued development, | 0:12:29 | 0:12:34 | |
that the company eventually launched the first counter top microwave oven. | 0:12:34 | 0:12:39 | |
And by the 1970s, they could be found on every high street in Britain. | 0:12:40 | 0:12:46 | |
But despite their popularity, people didn't always understand | 0:12:46 | 0:12:50 | |
how these amazing new machines actually worked. | 0:12:50 | 0:12:54 | |
There were people who saw these 'microwaves' as alien waves. | 0:12:54 | 0:13:00 | |
Or if a man stood in front of a microwave oven he'd become sterile, | 0:13:00 | 0:13:05 | |
or if you stood in front of a microwave while it was cooking, | 0:13:05 | 0:13:09 | |
some of the waves would actually come out through the oven door | 0:13:09 | 0:13:12 | |
and cook your own insides. | 0:13:12 | 0:13:14 | |
But they were all myths. | 0:13:14 | 0:13:16 | |
Some companies even tried to cash in on our worries, | 0:13:18 | 0:13:21 | |
selling what Watchdog exposed to be questionable leakage detectors. | 0:13:21 | 0:13:26 | |
We think these are trading on people's fears | 0:13:26 | 0:13:28 | |
because leakage just isn't a problem with modern microwaves. | 0:13:28 | 0:13:32 | |
But along with the myths, there were real dangers. | 0:13:32 | 0:13:35 | |
We've had a number of letters from people whose microwaves | 0:13:35 | 0:13:38 | |
have actually caught fire. | 0:13:38 | 0:13:40 | |
What might not have realised is that lots of bits of the modern | 0:13:40 | 0:13:44 | |
microwave are actually plastic. | 0:13:44 | 0:13:46 | |
But the trouble is, the plastic they're using in many of these | 0:13:46 | 0:13:49 | |
microwaves can be horribly burnt if food in the microwaves catches fire. | 0:13:49 | 0:13:54 | |
To find out how much damage this could cause, | 0:13:54 | 0:13:57 | |
Watchdog put it to the test. | 0:13:57 | 0:14:00 | |
We put a Christmas pudding, typical of the high fat, high sugar foods | 0:14:00 | 0:14:04 | |
that could catch fire if overcooked, into a microwave oven. | 0:14:04 | 0:14:08 | |
And then deliberately set the timer to its highest level. The result? | 0:14:08 | 0:14:13 | |
Well, it was clear to see. | 0:14:13 | 0:14:14 | |
Those are toxic fumes coming into the kitchen | 0:14:16 | 0:14:19 | |
and that's the burning plastic also coming down from the roof. | 0:14:19 | 0:14:22 | |
I don't think there are enough warnings in the instructions | 0:14:22 | 0:14:26 | |
that this can happen. | 0:14:26 | 0:14:27 | |
The industry knows some foods catch fire very easily, | 0:14:27 | 0:14:30 | |
like Christmas puddings and mince pies. | 0:14:30 | 0:14:32 | |
I'll pass our dossier to the Department of Trade's | 0:14:32 | 0:14:35 | |
consumer safety unit and I'll let you know what happens to this story. | 0:14:35 | 0:14:39 | |
A year after that report, | 0:14:40 | 0:14:41 | |
not only were we still getting reports of microwaves fires, | 0:14:41 | 0:14:46 | |
but manufacturers were still refusing to take responsibility for them. | 0:14:46 | 0:14:50 | |
So, we set out to prove it wasn't the fault of our Watchdog viewers and | 0:14:50 | 0:14:55 | |
others using them, but it was actually down to bad product design. | 0:14:55 | 0:15:01 | |
Here's what we think is wrong and what we'd like done about it. | 0:15:01 | 0:15:04 | |
Complaint number one - the timer controls. | 0:15:04 | 0:15:07 | |
MICROWAVE TIMER DINGS | 0:15:07 | 0:15:08 | |
'We bought five of the cheaper microwaves on the market | 0:15:08 | 0:15:11 | |
'and got normal people to try to set the manual timers accurately. | 0:15:11 | 0:15:15 | |
'They couldn't.' | 0:15:15 | 0:15:17 | |
Complaint number two - the instruction books. | 0:15:19 | 0:15:22 | |
Cooking times. The Asaki, for example, doesn't give any at all, | 0:15:22 | 0:15:26 | |
and the others give conflicting times. | 0:15:26 | 0:15:28 | |
Some say, if you're doubling the quantities of a recipe, | 0:15:28 | 0:15:31 | |
double the cooking times. Others say much less than that. | 0:15:31 | 0:15:34 | |
Now, I think specific cooking times are essential. | 0:15:34 | 0:15:36 | |
And you might agree after you've seen complaint number three. | 0:15:36 | 0:15:41 | |
Fire hazards. | 0:15:41 | 0:15:42 | |
'We, again, showed what could happen if the setting was wrong | 0:15:42 | 0:15:46 | |
'and overcooked some food.' | 0:15:46 | 0:15:48 | |
On this one, not only did the food catch fire, | 0:15:48 | 0:15:51 | |
but the door also blew open, and you can see here the flames | 0:15:51 | 0:15:54 | |
shooting up between the door and the main body of the oven. | 0:15:54 | 0:15:57 | |
'This time, the industry DID take notice. | 0:15:57 | 0:16:00 | |
'And just a month later, | 0:16:00 | 0:16:02 | |
'the programme was beginning to get results.' | 0:16:02 | 0:16:05 | |
Since then, Rumbelows, whose brand name is Asaki, | 0:16:07 | 0:16:09 | |
flew over two senior engineers from their factory in Korea | 0:16:09 | 0:16:12 | |
to visit us to look at our Watchdog tests. | 0:16:12 | 0:16:15 | |
As a result, all new Asaki microwave ovens are to have a thermal cut out, | 0:16:15 | 0:16:19 | |
and they're still looking at the type of plastic they're using. | 0:16:19 | 0:16:22 | |
'A great result. And others soon followed.' | 0:16:22 | 0:16:25 | |
Since the 1980s, the microwave industry has made massive strides, | 0:16:27 | 0:16:32 | |
things like thermal cut outs, better materials, most ovens | 0:16:32 | 0:16:36 | |
have a stainless steel interior, and all the instructions | 0:16:36 | 0:16:40 | |
in the manuals are very clear these days, so they're easy to use. | 0:16:40 | 0:16:44 | |
'So, it just goes to show how, through a series of leaps in design, | 0:16:44 | 0:16:48 | |
'exhaustive testing and a fair amount of viewer pressure | 0:16:48 | 0:16:52 | |
'the microwave has become the product we know and use today. | 0:16:52 | 0:16:56 | |
What do you use to wash your hair? Is it worth spending more | 0:17:02 | 0:17:06 | |
for a salon formulated shampoo, | 0:17:06 | 0:17:09 | |
or will an own brand value product work just as well? | 0:17:09 | 0:17:13 | |
Well, to tell us all about it is hair specialist, | 0:17:13 | 0:17:16 | |
or consultant trichologist, Iain Sallis. | 0:17:16 | 0:17:18 | |
Do you actually need to use a shampoo? | 0:17:18 | 0:17:20 | |
Couldn't you just get away with using some sort of body wash? | 0:17:20 | 0:17:23 | |
Well, I suppose, yes, you could just use a body wash | 0:17:23 | 0:17:26 | |
but, for hair, it is better | 0:17:26 | 0:17:28 | |
if we have more acidic properties to detergents, | 0:17:28 | 0:17:33 | |
what we call shampoos, because it closes the cuticles down, | 0:17:33 | 0:17:37 | |
and it makes our hair nice and shiny. | 0:17:37 | 0:17:39 | |
If you spend more, is it better for your hair? | 0:17:39 | 0:17:42 | |
It's more to do with the ingredients that's in them. | 0:17:42 | 0:17:45 | |
If you take the basic shampoos, they will have the basic detergents, | 0:17:45 | 0:17:50 | |
a foaming agent, preservatives, and perfumes. | 0:17:50 | 0:17:54 | |
Then you go in to the second bracket, | 0:17:54 | 0:17:56 | |
which is the mid-range shampoos and they will have | 0:17:56 | 0:17:59 | |
all the proteins in it, they will have pearlisers | 0:17:59 | 0:18:03 | |
to make it look nice, it'll have nicer perfumes to make it smell nice. | 0:18:03 | 0:18:07 | |
The higher range high street brands and the salons | 0:18:07 | 0:18:10 | |
sort of fall in to that bracket. | 0:18:10 | 0:18:12 | |
But then you go into the super priced £20-£50 shampoos, | 0:18:12 | 0:18:18 | |
which really is more to do with marketing. | 0:18:18 | 0:18:20 | |
The amounts of things that are in there like white truffle oil, | 0:18:20 | 0:18:24 | |
and caviar, anything else that you can think of, | 0:18:24 | 0:18:27 | |
they are in such small amounts, it really doesn't make a difference. | 0:18:27 | 0:18:32 | |
But there are shampoos which are more expensive | 0:18:32 | 0:18:35 | |
because of the specific ingredient for specific treatments to the scalp. | 0:18:35 | 0:18:40 | |
So, is the bottom line, stick with what you know | 0:18:40 | 0:18:42 | |
and go for a mid-range shampoo? | 0:18:42 | 0:18:44 | |
I think if you avoid the really bargain basement ones, | 0:18:44 | 0:18:47 | |
if you can, mid-range shampoos are good, | 0:18:47 | 0:18:51 | |
but after you go up from the £15-£20 mark | 0:18:51 | 0:18:55 | |
those are the type of shampoos that you start paying for the name, | 0:18:55 | 0:18:59 | |
the brand. There is a psychosomatic element to this so people | 0:18:59 | 0:19:05 | |
who pay more expensive shampoos will obviously feel more because | 0:19:05 | 0:19:08 | |
they won't turn round and go, "That was rubbish," | 0:19:08 | 0:19:10 | |
-if they've paid 50 quid for it. -The feel good factor. | 0:19:10 | 0:19:13 | |
-Iain Sallis, thank you very much. -You're welcome. | 0:19:13 | 0:19:15 | |
Back now to the headphones that claim to block out | 0:19:20 | 0:19:23 | |
the irritating sounds of the outside world that might otherwise | 0:19:23 | 0:19:26 | |
spoil your musical enjoyment. | 0:19:26 | 0:19:28 | |
Earlier, we asked three music buffs to rate the performance and | 0:19:28 | 0:19:32 | |
quality of three different sets of headphones currently on the market. | 0:19:32 | 0:19:36 | |
Their first test took place amid the incessant din of busy traffic. | 0:19:36 | 0:19:40 | |
This time, the headphones have something even louder | 0:19:40 | 0:19:43 | |
to compete with - roadworks. | 0:19:43 | 0:19:45 | |
First, a quick reminder of the products in our test. | 0:19:47 | 0:19:50 | |
The cheapest set of headphones is the JVC HA-NC80. | 0:19:50 | 0:19:55 | |
These cost just £30 | 0:19:55 | 0:19:57 | |
and, unsurprisingly, performed the worst in our first test. | 0:19:57 | 0:20:00 | |
I thought the JVC headphones were the most disappointing, definitely. | 0:20:00 | 0:20:04 | |
The sound was just a bit general, quite hazy. | 0:20:04 | 0:20:06 | |
Not much definition, not much clarity to it. | 0:20:06 | 0:20:09 | |
In second place, however, | 0:20:09 | 0:20:10 | |
were the top of the range product, the Sennheiser MM550-X costing £350. | 0:20:10 | 0:20:16 | |
But by far the best performer | 0:20:17 | 0:20:19 | |
when it came to both noise cancelling and sound quality on this test | 0:20:19 | 0:20:22 | |
was in fact the mid-range headphones, the AKG K490 NC at £150. | 0:20:22 | 0:20:28 | |
The AKGs were by far the best, the most effective noise reduction. | 0:20:28 | 0:20:32 | |
Overall, a very impressive sound. | 0:20:32 | 0:20:35 | |
But now it's time to give them something else to deal with. | 0:20:35 | 0:20:37 | |
The dulcet tones of major road works. | 0:20:39 | 0:20:43 | |
Because these headphones are actively cancelling the sound, | 0:20:43 | 0:20:46 | |
it'll be interesting to see how well they do with | 0:20:46 | 0:20:49 | |
a sudden change in the outside sound levels. | 0:20:49 | 0:20:52 | |
For this test we're going to need a workman... | 0:20:52 | 0:20:54 | |
..and some roadwork sounds. | 0:20:56 | 0:20:57 | |
PNEUMATIC DRILL ROARS | 0:20:57 | 0:20:59 | |
We, once again, sit each of our volunteers next to a busy road | 0:20:59 | 0:21:02 | |
and ask them to mark each set of headphones | 0:21:02 | 0:21:05 | |
out of five, for sound quality and how well they cancel out the noise. | 0:21:05 | 0:21:09 | |
Again, a possible 30 points up for grabs. | 0:21:09 | 0:21:11 | |
Already it's looking like our drilling is proving | 0:21:12 | 0:21:14 | |
a much tougher challenge. | 0:21:14 | 0:21:16 | |
The roadworks test was interesting | 0:21:16 | 0:21:18 | |
because there was an extreme difference in the three headphones. | 0:21:18 | 0:21:21 | |
Overall, once more, everyone agreed that the mid-range AKG coped | 0:21:21 | 0:21:25 | |
the best with both noise cancelling and sound quality. | 0:21:25 | 0:21:28 | |
The AKG headphones seemed to do the best job of | 0:21:28 | 0:21:32 | |
separating the drill sound from the music. | 0:21:32 | 0:21:35 | |
Again, the most expensive product did a good job of cutting out | 0:21:35 | 0:21:38 | |
the noise, but it was at the expense of sound quality, | 0:21:38 | 0:21:41 | |
with the cheapest, the JVC, | 0:21:41 | 0:21:43 | |
performing the worst in both categories. | 0:21:43 | 0:21:46 | |
The JVC seemed to take the bass off but you got this pinging drill noise | 0:21:46 | 0:21:50 | |
at the top which was, actually, even worse than | 0:21:50 | 0:21:53 | |
the drill sound in its entirety. | 0:21:53 | 0:21:56 | |
JVC told us that the headphones we tested, the HA-NC80, | 0:21:56 | 0:22:01 | |
are their entry level product, | 0:22:01 | 0:22:03 | |
and they are confident the higher spec products in their range | 0:22:03 | 0:22:05 | |
would perform better against the other headphones featured in Our test. | 0:22:05 | 0:22:09 | |
But none of our three products managed to cut out the drilling sound completely. | 0:22:09 | 0:22:13 | |
So, why did they struggle? | 0:22:13 | 0:22:15 | |
So sound is made up of waves. A simple sound wave might look... | 0:22:15 | 0:22:19 | |
something like this. | 0:22:19 | 0:22:21 | |
What these headphones are trying to do is to cancel that wave | 0:22:24 | 0:22:28 | |
by generating the opposite wave within your ear. | 0:22:28 | 0:22:32 | |
So the opposite wave would look just like this. | 0:22:32 | 0:22:36 | |
And if the headphones get it right, and they generate the opposite wave | 0:22:38 | 0:22:42 | |
to be perfectly opposite to the original one, | 0:22:42 | 0:22:45 | |
then what we end up with is a nice, flat, silent sound level. | 0:22:45 | 0:22:50 | |
When we get a sudden sharp noise, like a roadworks, or similar, | 0:22:50 | 0:22:55 | |
what happens is, instead of this wave form being nice | 0:22:55 | 0:22:59 | |
and predictable and steady, the wave form will be going up | 0:22:59 | 0:23:01 | |
and down very quickly and expanding in and out very quickly. | 0:23:01 | 0:23:05 | |
And that's much, much harder for the headphones to track | 0:23:05 | 0:23:08 | |
and to generate the opposite sound. | 0:23:08 | 0:23:10 | |
But, all in all, it's not a bad attempt | 0:23:10 | 0:23:13 | |
when you consider all that the modern world has to throw at them. | 0:23:13 | 0:23:16 | |
I think they're wonderful pieces of equipment. | 0:23:16 | 0:23:19 | |
It's staggering, in fact, that they can achieve what they do | 0:23:19 | 0:23:22 | |
if used in the right environment, | 0:23:22 | 0:23:24 | |
and, as we've seen, that's particularly good | 0:23:24 | 0:23:26 | |
where there's a nice, constant source of noise. | 0:23:26 | 0:23:28 | |
We return now to home security. | 0:23:32 | 0:23:34 | |
and the problems caused by criminals lock snapping. The good news? | 0:23:34 | 0:23:39 | |
Manufacturers and industry experts | 0:23:39 | 0:23:41 | |
have been working hard to come up with a solution to reduce the risk | 0:23:41 | 0:23:45 | |
and to bring greater security to our homes. We've been taking a look. | 0:23:45 | 0:23:50 | |
The British Standards Institution. | 0:23:52 | 0:23:54 | |
Here, they test doors and locks on behalf of manufacturers | 0:23:54 | 0:23:57 | |
to standards way above those that are required by law. | 0:23:57 | 0:24:00 | |
In fact, they test them | 0:24:00 | 0:24:02 | |
to their own Kitemark standard, something they call PAS 24. | 0:24:02 | 0:24:06 | |
It actually takes two days to carry out the full tests. | 0:24:06 | 0:24:10 | |
So, today Kevin, or Kitemark Kev as he's fondly known, is going | 0:24:10 | 0:24:14 | |
to take us through some of the highlights, | 0:24:14 | 0:24:16 | |
on a door we know already meets the all the requirements. | 0:24:16 | 0:24:19 | |
One of the tests that we have in PAS 24 is the endurance test. | 0:24:21 | 0:24:24 | |
The endurance test simulates somebody coming in | 0:24:24 | 0:24:27 | |
and going out of their front door or back door. | 0:24:27 | 0:24:29 | |
Let me introduce Jeff. | 0:24:29 | 0:24:31 | |
Jeff is our robot. | 0:24:45 | 0:24:47 | |
Jeff does all the testing for us. Jeff does 50,000 cycles. | 0:24:47 | 0:24:51 | |
That's the equivalent of you opening and closing your door | 0:24:52 | 0:24:55 | |
ten times a day for 14 years. | 0:24:55 | 0:24:58 | |
Jeff's on...oh, 49,000 cycles so we should probably leave him to it. | 0:24:58 | 0:25:05 | |
In addition to the endurance test | 0:25:12 | 0:25:14 | |
we also subject the door to an air test, a rain test, | 0:25:14 | 0:25:18 | |
and to a wind gusting test. | 0:25:18 | 0:25:20 | |
We've placed the door into our special weathering test rig | 0:25:20 | 0:25:23 | |
and we're just about to do an air test on the product. | 0:25:23 | 0:25:26 | |
In order to pass this test, the door needs to be able to | 0:25:28 | 0:25:31 | |
withstand 300 pascals, a measure of air pressure, | 0:25:31 | 0:25:34 | |
on the outside without too much leaking through to the inside. | 0:25:34 | 0:25:38 | |
This one's passed with ease. So it's onto the rain test. | 0:25:38 | 0:25:41 | |
We have simulated rain pouring on the outside of the door, | 0:25:53 | 0:25:56 | |
and we're going to slowly increase the pressure in our test rig | 0:25:56 | 0:25:59 | |
to simulate lighter winds, and then we're going to look for leakage. | 0:25:59 | 0:26:03 | |
So far, so good. | 0:26:04 | 0:26:06 | |
The door's already survived some pretty extreme weather conditions. | 0:26:07 | 0:26:11 | |
Meanwhile, Jeff's still doing his thing. | 0:26:11 | 0:26:14 | |
Now it's time for the security tests. | 0:26:14 | 0:26:17 | |
What we're going to do is a number of different tests on the door | 0:26:17 | 0:26:20 | |
to simulate an opportunist burglar attacking the door, | 0:26:20 | 0:26:22 | |
attacking your home. | 0:26:22 | 0:26:23 | |
The tests range from trying to lever the door open, to smashing it | 0:26:26 | 0:26:29 | |
with a battering ram. | 0:26:29 | 0:26:31 | |
All designed to simulate the pressure a burglar might | 0:26:31 | 0:26:33 | |
put on your door when trying to break in. | 0:26:33 | 0:26:36 | |
Most of the tests we've done so far have been based on machines. | 0:26:36 | 0:26:38 | |
The next test is a manual attack test. We're going to attack | 0:26:38 | 0:26:42 | |
the door using another one of our members of the team. | 0:26:42 | 0:26:44 | |
You've met Jeff, now meet Dave. | 0:26:44 | 0:26:46 | |
Dave, you have three minutes, do your best. | 0:26:47 | 0:26:50 | |
Or your worst. | 0:26:50 | 0:26:51 | |
We can't show you exactly what Dave is up to, | 0:26:53 | 0:26:55 | |
safe to say though, he's really going for it. | 0:26:55 | 0:26:58 | |
But the door is up to the challenge. | 0:26:58 | 0:27:00 | |
OK, so this test has now been completed, | 0:27:00 | 0:27:03 | |
and Dave is still on the outside of the door, | 0:27:03 | 0:27:05 | |
so on the outside of the house, | 0:27:05 | 0:27:07 | |
so this door has passed this particular test. | 0:27:07 | 0:27:09 | |
The door is doing well so far. | 0:27:09 | 0:27:11 | |
But, as we saw earlier, there is one way a burglar can get through | 0:27:11 | 0:27:15 | |
some UPVC doors in just eight seconds - lock snapping. | 0:27:15 | 0:27:19 | |
As easy as that. | 0:27:20 | 0:27:22 | |
So after manufacturers developed a new type of lock designed | 0:27:22 | 0:27:25 | |
to withstand this kind of attack, the police asked Kevin and his team | 0:27:25 | 0:27:28 | |
to help devise a new standard in order to test it. | 0:27:28 | 0:27:32 | |
We've written a standard called TS007, | 0:27:32 | 0:27:34 | |
and what you're going to see in a few moments is one of our guys | 0:27:34 | 0:27:38 | |
using those attack methods to demonstrate the product | 0:27:38 | 0:27:41 | |
that meets those requirements actually will keep the burglar out. | 0:27:41 | 0:27:45 | |
Dave, have a go. | 0:27:45 | 0:27:47 | |
And it's clear, this lock is more than up to the job. | 0:27:51 | 0:27:55 | |
No way. | 0:27:55 | 0:27:57 | |
There are locks that comply to this new standard currently | 0:27:57 | 0:28:00 | |
on the market, but if you wish to keep your home safe in the meantime, | 0:28:00 | 0:28:04 | |
make sure you put bolts down, if you've got them, | 0:28:04 | 0:28:07 | |
double lock, if you can, and, when leaving the house, | 0:28:07 | 0:28:10 | |
make sure it looks like someone's at home. | 0:28:10 | 0:28:13 | |
Security lights or a timer are a good way to do this. | 0:28:13 | 0:28:16 | |
