6.5 Time of Inspection 6.5.1 Inspection on New Installations; • spring adjustment pressure-relief valves should be field inspected and tested before they are installed on process equipment. • If the factory setting is done in a nearby shop, this additional testing may be unnecessary. • Pressure- and/or vacuum-vent valves on atmospheric storage tanks should also be inspected after installation but before the tank is hydrostatically tested or put into service. should also be inspected whenever the tank is taken out of service.

Routine • inspection least interferes with the process and maintenance manpower is readily available. Unscheduled Inspection • If a valve fails to open within the set pressure tolerance, it requires immediate attention. Inspection After Extended Shutdowns • On extended shutdown should be inspected and tested before the resumption of operations. • On change in operating conditions is to follow the shutdown.
