Résumé
ISO 23551-4:2005 specifies safety, constructional and performance requirements of valve-proving systems, hereafter referred to as VPS, intended for use with gas burners and gas-burning appliances. It also describes the test procedures for checking compliance with these requirements and provides information necessary for the purchaser and user. ISO 23551-4:2005 applies to all types of VPS which are used for the automatic detection of leakage in a gas burner section having at least two valves designed in accordance with ISO 23551-1 and which give a signal if the leakage of one of the valves exceeds the detection limit.
ISO 23551-4:2005 applies to VPSs with a declared maximum working pressure up to and including 500 kPa for use in systems using fuel gases.
ISO 23551-4:2005 does not apply to VPSs for use in explosive atmospheres.
