Cylinder Test Standards

I've come across a pile of old cylinders, all outside test. They were
used by a diver who had access to his own compressor and blending kit,
for who test dates and relevant British Standards were of only
peripheral interest!

Can someone remind me of the relevant British Standards which cover
diving cylinders, so I can see if any of these can be tested and then
used underwater?

The ones I know of are:

BS 5054 Pt. 1 Steel
BS 5045 Pt.3 Al.

which I think have been superseded by:

BS EN 1968:2002 Steel
BS EN 1802:2002 Al

Are there any other standards which are valid for scuba cylinders?

I'm fairly certain the day of the week it was manufacturd on is relevent
provided that the week of manufacture is an even number (calculated
from the 4th full moon of the year(5th on leap years))and that the
original test stamp was done by a guy called Kevin.

Of course this applies only to Northern diveshops. It has to de an odd
numbered week for southern.

Seriously though. Try a quick check of the Google archives as I think
this
was covered earlier in the year, however IIRC it's a minefield.

The marking legislation's fairly convolouted as well.

Good luck.
