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?
