If the closure (lid) on an IBC is designed to function as a non-reclosing pressure reliet device with a burst pressure of 20 PSIG, then per 49 CFR 178.814(b) the 20 PSIG rupture disc may be replaced with a rupture disc that has a minimum burst pressure of 29 PSIG when conducting the hydrostatic pressure test. Please advise if Hercules' interpreiation of this regulation is correct. Also, must the 20 PSIG burst pressure be marked on the container and/or closure? Thank you for your time and cooperation.
