Hi I thought this might be of interest as this has been mentioned on another forum.
There is a proposal to introduce a new document- BS EN ISO 18119 Transportable gas cylinders – Periodic inspection and
testing of seamless cylinders- which would require scuba cylinders to be visually inspected and stamped annually between the 5 year hydraulic tests instead of at 2.5 years as present.
This will presumably affect all those who fill off scuba cylinders and perhaps others.
I am not a member of any other airgun forums but have not seen this discussed here
Are the airgunning community aware of this?
