ISO 15996:2017规定了包含残余压力装置的气瓶阀（以下简称残余压力阀）的设计、型式试验和标记要求。本文件适用于以下类型的RPV: a） 拟安装在可再充装运输气瓶上的气瓶阀； b） 气缸组的主阀（不包括球阀）； c） 带集成压力调节器（VIPR）的气缸阀或主阀； d） 压力桶和压力管的阀门； 输送压缩或液化气体的容器。 注:如果不存在模棱两可的风险，则本文件中的气瓶、压力桶、管道和气瓶组均使用“气瓶”一词。 这些要求是对ISO 10297中要求的补充。 对于RPD单机设备，也可以使用本文档。 ISO 15996:2017不适用于便携式灭火器、低温设备、低压制冷剂气体（气瓶试验压力小于50 bar）、溶解气体或液化石油气（LPG）的RPV。

ISO 15996:2017 specifies design, type testing and marking requirements for cylinder valves incorporating residual pressure devices, hereinafter referred to as residual pressure valves (RPVs). This document applies to the following types of RPVs: a) cylinder valves intended to be fitted to refillable transportable gas cylinders; b) main valves (excluding ball valves) for cylinder bundles; c) cylinder valves or main valves with integrated pressure regulator (VIPR); d) valves for pressure drums and tubes; which convey compressed or liquefied gases. NOTE Where there is no risk of ambiguity, cylinders, pressure drums, tubes and cylinder bundles are addressed with the collective term "cylinder" within this document. These requirements are in addition to those in ISO 10297. For RPD stand-alone devices this document can also be applied. ISO 15996:2017 does not apply to RPVs for portable fire extinguishers, cryogenic equipment, low pressure refrigerant gases (cylinder test pressure less than 50 bar), dissolved gases or liquefied petroleum gas (LPG).
