Thread: CE Mark - real and fake
19/01/2018 18:22:52

The CE mark is not meaningless, it signifies a declaration by a responsible individual who is resident within the EU that the apparatus complies with the relevant directives and EU standards. Most CE marked products are not a problem, most of the manufacturers, importers and retailers use the system responsibly because they don’t want to incur any liability for anything going wrong with the product. The problems occur when people import appliances often unaware of their responsibilities until either something goes wrong or Trading Standards become involved. They then go to an independent test house to get the OK on their products only to find, quite often, that they have several containers full of goods that cannot legally be sold in the EU.

The system is not foolproof because the requirements are not enforced until after the fact. Prior third party safety certification is not enforced anywhere in the world AFAIK. The USA has compulsory third party certification for apparatus used in the workplace, but this doesn’t apply to products for the domestic environment.

It’s illegal to sell a cord-connected appliance in the UK without a certified UK plug fitted. Reputable inporters either have certified UK plugs fitted or have certified adapters fitted to the European plug, which must not be removeable without the use of a tool. The dealer is breaking the law by selling an appliance in the UK in this condition. The appliance would have been useable in the rest of Europe, so the CE mark would appear to be valid.

You are confusing PAT testing with third party type testing which is carried out at accredited test houses. The test houses are audited by UKAS at least annually. The UKAS audit includes chucking that the testing engineers are sufficiently qualified and experienced to carry out the required testing. The tests will include (depending on the type of apparatus) heating, electric strength, insulation resistance, creepage distances and clearances, accessibility of live parts, earth bonding, internal wiring and connections,mechanical hazards, user Instructions, servicing instructions, connection to the mains supply, physical stability and more.

I bought a bench power supply from a UK dealer, although plainly of Chinese manufacture. It came with a moulded 3 pin plug which didn't have a fuse, or any means of fitting one, but the whole ting was CE marked. Trading Standards took it up but I never heard the outcome
Wire cutters and a new plug at least cured that, but it didn't last any time at all before the LED displays started playing up

If I bought something that was fitted with an illegal plug, I would return it immediately to the vendor and demand my money back. I certainly wouldn’t use it or modify it in any way.

With BREXIT, will the UK still use the CE mark or revert back to BS ?
BobH

The CE mark will continue to be used, the BSI mark was never mandatory.

Given that most of our electrical and electronic gear is made out there, warning that "marks are probably faked" is neither helpful or likely.

If you want to minimise the risk of dodgy gear, buy it from a reputable Western outfit. As Neil says, a failure to ensure stuff has been tested properly is a serious criminal offence. If you like fakery, want to electrocute yourself or burn down your property, you are free to buy from Aliepxpress, Banggood etc

It used to be a requirement to have equipment tested and certified by authorised 3rd parties (BSI etc) but the relaxation to allow "self certification" came out of Europe. This reduction in "red tape" and over regulation is something that many people are very enthusiastic about.

If you claim to have self certified, you need to be prepared to provide evidence, so you'd be pretty dumb to lie about it, particularly if you live here.

Before the Low Voltage Directive was enacted (which was EU legislation) there was no requirement to safety test any apparatus for domestic use in the UK.

Thread: Cubital tunnel sydrome or ulna nerve entrapment

Yes, totally, I certainly don't regret it. If you do a lot of typing on the PC an ergonomic mouse and keyboard is a great help, both before and after the operation.

The electrical tests show which nerve has the problem, they are essential because in most cases it's not clear which one it is. The carpal tunnel operation involves making an insiscion at the base of the palm in order to clear out the tunnel to relieve the pressure on the nerve. The operation is usually performed under local anaesthetic and takes about 25 minutes.

The Cubital tunnel operation is always performed under general anaesthetic because the nerve is quite long and has to checked at several points where it may be constricted.

I wouldn't trivialise your problems but your symptoms sound fairly mild, and I would wait a while before going ahead. These procedures are painful during the recovery period and it's often some time before resuming normal activities.

Bert

I have have both carpal tunnels and cubital tunnnels done, the former with local and the latter with general anaesthetic. I advise you to have a private electrical test done to establish which operation is required. The NHS electrical tests are notoriously unreliable, you can have the operation done on the NHS later, that will probably be ok. Any more information, please ask.

Best regards

They are worth the visit, the car parking has been better lately because they have used the field on the other side of the road.

There are bargains to be had, particularly machine stands and cabinets.

They also do drinks and burgers on their open days.

Neil.

Back in the early 80's we used to be able to buy a water injection unit that added a small amount of water to the air/petrol mixture from the carburetor. Supposedly to cause a better fuel burn. I also remember something about a similar system being used in early fighter plane engines.

Paul.

The Focke Wulfe 190 used water injection to achieve 'emergency power' for short periods of time, I'm sure other planes did as well.

The Harrier used a lot of water injection to boost the power as you will be able to see when you go to Brooklands

There is also Mercedes Benz World opposite Brooklands which is free to enter. Brooklands is well worth a visit, I go five or six times a year.
