标准范围

本文件规定了以下阀门[包括球阀和带集成压力调节器（VIPRs）的阀门]的检查和维护要求:a） 可重复充装的可运输气瓶；b） 气缸组；c） 压力桶和压力管；输送压缩的、液化的或溶解的气体。本文件不适用于液化石油气（LPG）阀门。注:如果不存在模棱两可的风险，则本文件中的气瓶、气瓶组、压力桶和管道均使用“气瓶”这一统称。本文件适用于定期检查气瓶、气瓶组、压力桶和管道时重复使用的阀门，也可在任何其他时间使用，例如在更换气体服务时（见ISO？11621）。本文件不适用于阀门的常规检查，例如在气瓶充气时进行的检查。

This document specifies requirements for the inspection and maintenance of valves [including ball valves and valves with integrated pressure regulator (VIPRs)] for:a) refillable transportable gas cylinders;b) cylinder bundles;c) pressure drums and tubes;which convey compressed, liquefied or dissolved gases.This document does not apply to valves for liquefied petroleum gas (LPG).NOTE       Where there is no risk of ambiguity, gas cylinders, cylinder bundles, pressure drums and tubes are addressed with the collective term “gas cylinders” within this document.This document is applicable to valves reused at the time of the periodic inspection of gas cylinders, cylinder bundles, pressure drums and tubes, and can be applied at any other time, e.g. at a change of gas service (see ISO 11621).This document does not apply to the routine inspection of valves, e.g. carried out at the time of a gas cylinder filling.
