标准范围

ISO 23551-4:2005规定了用于燃气燃烧器和燃气设备的阀门验证系统（以下简称VPS）的安全、结构和性能要求。它还描述了检查是否符合这些要求的测试程序，并为买方和用户提供了必要的信息。ISO 23551-4:2005适用于所有类型的VP，用于自动检测燃气燃烧器部分的泄漏，该部分至少有两个阀门按照ISO 23551-1设计，如果其中一个阀门的泄漏超过检测限值，则会发出信号。ISO 23551-4:2005适用于在使用燃气的系统中使用的最大工作压力不超过500 kPa的VPS。ISO 23551-4:2005不适用于爆炸性环境中使用的VPS。

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.
