the 03/07 one, should need re-testing 2008 mate(5 yr). The Other one, not sure mate.

Your bottle needs testing before the end of July 2008 (2008/07). The testing happens every 5 years on your bottle, so you have one in 2008 and the other in 2013. The bottle has a working life of 15 years, so at the end of July 2018 it will become junk.
Don't know on the other one.

Do you have a pic of the other bottle

 

[***tom***]

yeah here it is

its not clear due to rubbish camra and light bit it says REHYROTEST BEFORE:

 

[Tom Allen]

can you take a pic of the whole label and a pic of any writing aroud the neck area of the bottle.

 

[***tom***]

you cant see whats written on the neck of the bottle because its indented and wont come up on a photo but heres what it says


15E USA (P) C247019 AA6061
6.46MM 1.23KG .72L PW207 PH311BAR
(SIGN 2 VIRTICAL LINES JOINED AT THE TOP WITH A WAVY LINE) EN1975 GB (A) 1266 2005/06

things in brackets may not be exact and as for the 2 lines joined at the top with a wavy line i cant find the symbol for

 

[Tom Allen]

That's the Pi symbol, and the 2005/06 is the born date of the bottle, which means the next test is in june 2010 if the same 5 year rule applies to ally bottles, if not it may be 3 year intervals which would be June 2008.

ok cheers guys for all your help

Make sure you are aware of the working pressures on each bottle. The black bottle i think is 3000psi, and the grey bottle may be 4500/5000psi but i can't see the markings well enough to say from the pic.
