Posted By Ian Futcher I'll get the hang of these posts eventually!! forgot to paste the link http://www.bcga.co.uk/preview/cylinder_testing.php

Posted By Brian Hagyard Darren Don’t know if this link is of any use, but try www.hse.gov.uk/foi/inter...fod/oc/300-399/307_5.pdf have not had much dealing with oxy-acetylene cylinders but have some experience of other types of gas cylinders and on these the test date is usualy stamped on the neck or collar of the cylinder. I don’t think the regulations cover the guages – if part of a fixed system then may be subject to the pressure systems safety regulatins 2000, but I suspect you are refering to the mobile systems I have seen in garages etc. In these cases I belive you should apply the Provosion and Use of Work equipment Regulations and hence have a servicing/maitance regime. I would ask the guage manufacture for advice. Good Luck. Brian.

Posted By Brian Hagyard Jane You are quite correct and my apologies for a quick response that could have been misleading. What I meant was the regulations do not usually apply to portable cylinders that are filled elsewhere (such as those used in SCUBA) as they are covered by different regulations. Brian.

Posted By MP The criteria is for them to be within test when they are filled. The cylinders will be inspected at every fill by the gas company and re-tested every 10 years, for example, for Oxygen, Nitrogen, Argon, etc. There is usually nothing regarding test status for the user to be concerned about. There will be a date stamp on the shoulder. These cylinders can still be safely used if they go out of test when on-site as the view is taken that the pressure in the cylinder will be reducing all the time as the gas is used.
