I think they're both 5 year tests, and it's only bottles "born" in 2003 that need testing after 3 years.which bottles need a testing after five years and which after three?
as ive got two bottles both fibre wrap with the "born" date on them both have a 15Yr life but one says 2004/05 07
the other 2004/05 09
does one need testing every 3 and the other 5 ? if you see what i meen.
thanks
