Objective Quality Evidence.
Maximum Operating Pressure. The highest pressure that can exist
in a system or subsystem under normal operating conditions.
This pressure is determined by such influences as pump or
component shutoff pressures, pressure regulating valve lockup
(no flow) pressure, and maximum pressure at the system source.
Maximum System Pressure. Maximum system pressure is the highest
pressure that can exist in a system or subsystem during any
Normal, abnormal, and emergency operation and
casualty conditions shall be considered in determining the
maximum system pressure.
In any system with relief valve
protection, the nominal setting of the relief valve shall be
taken as the maximum system pressure. (Relief Valve
accumulation may be ignored.)
