Does anyone know if NHRA requires the bottles to be hyrdro-tested every 5 years? 1 of the speed shops in the area requires this for filling, but the other 2 do not. I know my bottles do not leak (I used them last year, the last year of their certs). It's 45 a bottle to have them tested...really don't feel like throwing away the money if I don't have to.
If it's required, I'll probably just test 1 bottle as my 'track' bottle, and keep the other 2 (or 3 or 4) for 'street' use.
Also...does anyone know how to read the certs? I just purchased a new bottle, and do not know the date on it. It says "TC-3ALM124" on the top line, "DOT-3AL1800 W52581 LUXFER 07A97" on bottom line
