What standards / tests does a new manufacturer have to...

Chris1234567

I'm wondering what standards a small scale parts manufacturer has to adhere to, and what test should be carried out?
Does anyone know of the relevant document?

Thanks in advance.

Depends but basically nothing, unless the buyer wants something.
Or you could be more specific.

This. So very much this.

Think what you need to get tested and you may find Google a good friend.

None at all.
However there are many, many relevant standards and documents.

Not corrent, I'm afraid. Certain parts may need to adhere to certain key standards in order to attain relevent safety marks/ certification.

We have no idea what these 'small parts' the OP is talking about may be.

Ok yeah safety critical parts will have to adhere to standards, but generally, you don't HAVE to adhere to standards. It does depend entirely what the parts are though, what you're trying to achieve etc etc.
I've no idea about bike component specific standards, however there are plenty of quality management standards and certification bodies out there that cover pretty much anything.

Thanks for the replys.
At the moment we are making mainly small parts such as lock-rings, aheadset rings, bolt caps etc not the most safety related parts.
But thinking to move onto cranks, stems etc. I thought I had read that products make in the UK had to be CE approved?
I can't find anything on it now though! I was up Untill 4:30am this morning searching but couldnt really find anything.

Thanks.

Nope. But out of curiosity I checked four boxes lying around - Deore crankset, KCNC stem, Bontrager tyre and Planet X tubes. None have any safety or other standard printed on them.

There are standards for importing whole bikes and probably standards for components. They are to do with safety. contact Intertek - I know they do testing for imported Taiwanese bikes - I used to work for them!

Thanks for that, I'll look into it.

Considering the drek sold by Toys r Us etc, the standards can't be very high. Or the testers are doing a really sh1t job.

The four different CEN standards that were published in the EU Official Journal are:

EN 14764 for City and Trekking bicycles
EN 14766 for Mountain bicycles
EN 14781 for Racing bicycles
EN 14872 for Bicycles – Accessories for bicycles – Luggage carriers.

EN 14765 for childrens bikes has not yet been published.

And your point is?

All the above are correct, however are for whole bikes (the last published one is for accessories such as bags etc but not parts) that are sold in the UK or imported into the UK. There is nothing to state that you can not change components who do not have to comply with the above rules.

Standards are obviously lower than Crudcatcher.

Those EN standards may be only a specification for the bikes or components or they could include or refer to tests in other standards. The last section in the standard (known as Annex ZA) gives the "level of attestation of conformity" which sets out which tests must be done, if the manufacturer can do them themselves or use an independent test house and the frequency of factory production control inspections.

And yes, this rubbish is part of my job, albeit in a different industry. After reading a few ENs, watching paint dry seems action-packed...
