标准摘要
[中文适用范围]： 本文件规定了用于焊接、切割和相关工艺的设备可接受的最大外部气体泄漏率，并提供了测量程序。 它适用于从软管连接点（钢瓶阀门出口或燃气供应设备的连接点）向吹管供气的单个组件。 本标准不适用于燃气供应厂。 注：关于最大外部泄漏测量的测试方法和条件/程序的具体要求可以在单独的标准中给出，例如用于吸气式吹管的 ISO 9012。 关于应用的方法和条件，单独的标准优先于本文件。 适用本文件中的最大外部泄漏。 [外文原描述]： This document specifies the maximum external gas leakage rates which are acceptable for equipment used for welding, cutting and allied processes and provides the procedures of measurement. It applies to individual components which are used in the gas supply to a blowpipe from the connecting point of the hose (outlet of the cylinder valve or connecting point to a gas supply plant). It does not apply to gas supply plant. NOTE Specific requirements on the test method and conditions/procedure for measurement of the maximum external leakages can be given in individual standards, e.g. ISO 9012 for air-aspirated hand blowpipes. Concerning the method and the conditions to be applied, the individual standard takes precedence over this document. The maximum external leakages according to this document apply.
