Dear Experts,
I've a concern regarding , valves.
our client is insisting to submit individual pressure test certificates of control valves , for 6" & above lines.
but the valve supplier's provided certificate showing,it is for 60 valves of same kind.
Is each valve no need to pressure tested at manufacturer's premise before delivery? which code / std refers individual/random pressure test criteria of valves?
