PCP cylinder testing

[RobF]

In the rules for testing compressed gas pressure vessels.

As hareng above has put, there might even be a link in the stickies.

Which rules are they then?

Here's the rules. TPED.

Here's the UK law carrying out the EU directive

http://www.legislation.gov.uk/uksi/2.../contents/made

It makes reference to the directive, which in turn defines what is covered in section 2. There's some exceptions in section 6 from here.

So you'll have to do some cross referencing.

No where does it say under 500cc doesn't need a test. Well not that I can find.

What it says is that if it's manufactured to spec it should carry markings which should cover you for 10 years. Like Pi for instance (which is on at least one of my Walther tubes). This is why ISSF don't allow cylinders over 10 years in their competitions because presumably there's no way to remark thin walled cylinders even if they're tested, or perhaps because they're deemed to be industrial cylinders (pi) there isn't a established test method.

Industrial cylinders are covered by different tests to scuba cylinders designed to be used for breathing air... assuming they have the correct markings.

Does anyone know if PCP cylinders can be pressure tested and if so, who might do it ?
On a related issue, if a cylinder was to fail would it likely be a split in the steel rather than a full on explosion ?
Thanks

HW 100 cylinder that is made of stainless steel has a stamp asking fo rthe cylinder to be tested after 10 years from the date of manufacture. Who does it in the UK , I don't know.

Does it ask for a Pressure test or a visual inspection??
