Manufacturing standard for diving cylinders

[Sarah Gauci Carlton]

Can anyone tell me the current manufacturing standard for diving cylinders, that has replaced BS5045/1/3. I know the current test standard, but not the manufacturing standard.
I know I've got it somewhere - just can't find it.
Thanks,
Sarah
