適用范圍：This part of ISO 4126 covers the application and installations of safety devices such as safety valves, safetyvalves and bursting disc safety devices in combination, pilot-operated safety valves and controlled safetypressure-relief systems for the protection of pressure equipment. ISO 4126-6 covers the selection, applicationand installation of bursting disc safety devices.This part of ISO 4126 describes the normative requirements for applications and installations of safety devicesto protect static pressure equipment. The information contained in this part of ISO 4126 assumes single-phaseflow of the fluid discharged from the safety device. ISO 4126-10 provides guidance specific to two-phase flowconditions.Equipment connected together in a system by piping of adequate capacity, which is free from potentialblockages and does not contain any valve that can isolate any part, can be considered to be a safety systemfor the application of pressure relief.This part of ISO 4126 does not deal with other safety devices, such as safety related monitoring, control andregulation devices and other limiting devices allowed by some national regulations.
