I wonder if anyone can help me please? I am working along side an mechanical engineer who has been building/repairing machines all his life in the working environment.
My question is - both he and I would like to build a machine to sell to a client.

How can we apply a CE registration to it? I appreciate all materials have to be up to standards and that workmanship must not leave the machine in a dangerous condition of any shape or form.

Any guidance would be much appreciated!

Thank you.

Hi sparkyaj, not got the link to hand but I looked it up before and I was under the impression that a CE marking was basically a self-certification system, ie. anyone can put the sticker on anything!

That would seem to be the case Weirdbeard, judging by some of the carp we see with CE markings on!

OK, thank you for the link - but how can we find out what rules apply to the build? I spoke to the ECA today, but they advised that it is more technical...

Thank you for your thoughts so far.

What kind of machine is it? Have you looked at the Machinery Directive? Have a look at http://ec.europa.eu/enterprise...machinery/index_en.htm and at the Commission Guide referred to on that page.

This is the guidance notes document on the UK regulations that implement the Machinery directive: http://www.bis.gov.uk/files/file52968.pdf

Greg Kervill's 'Practical Guide to the Low Voltage Directive' is a useful guide to CE compliance though it focuses on EN 60950 (IT equipment) and is now rather dated. It's still worth a read (but maybe not worth £50).

The CE mark is a wide ranging thing, it encompasses safety (Low Voltage Directive), the Machinery Directive, Electromagnetic Compatability etc. You cannot just stick a CE sticker on your equipment without good grounds to expect your equipment to pass. If you do you are on extremely dodgy ground.

Firstly carry out an assessment on the machine you are proposing to build and find out what parts of the standard are applicable, probably LVD and EMC. As you are building the machine document everything, ensure that the parts you buy are CE marked (a common mistake to buy cheap parts that have not been tested), finally remember CE + CE does not equal pass, just because you have built your machine using CE tested parts does not mean that it will pass...
It sounds daunting but it does not have to be. With good engineering paractice, a dollop of common sense and reference to the applicable standards you should not have a real problem.
Look up a Technical Construction File on the net..

If you need some further help, PM me

If it's a machine, it needs to comply with the Machinery Directve!
More accurately, if you're in the UK, the Supply of Machinery Safety Regulations 2008.

A CE mark is a certificate from the manufacturer (signed by the responsible person representing the company) which certifies that the item meets all of the applicable legislation relevant to it. CE marking is necessary for items put on general sale, and may not be necessary for custom items, where the purchaser and manufacturer agree a specification together and accept joint responsibility. For example ships and power stations are not CE marked as such, although they meet many varied pieces of legislation. The greatest difficulty you may face is the EMC directive, because testing is difficult and expensive for one offs, and simply using compliant parts is a long way from ensuring compliance. That said there are actually few problems with much imported stuff, lots of which is not compliant with EMC regs. The document you need to make is called a Technical Construction File, where you keep information as to how the machine is made and how you expect to achieve compliance with the regulations, which may be simple by using other CE marked parts, or complex by testing as appropriate along with the measured results.

I hope that helps a little.
