本文件规定了设备可接受的最大外部气体泄漏率 用于焊接、切割和相关工艺，并提供测量程序。 它适用于从连接管道向吹管供气时使用的单个部件 软管的连接点（钢瓶阀门的出口或燃气供应装置的连接点）。这不适用 去煤气供应厂。 注意测试方法和条件/程序的具体要求，以测量 可在个别标准中给出最大外部泄漏量，例如ISO 9012中的吸气式手吹管。 关于应用的方法和条件，单独标准优先于本标准 文件本文件规定的最大外部泄漏适用。交叉引用:ISO 15296ISO 2503购买本文件时可获得的所有现行修订均包含在购买本文件中。

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.Cross References:ISO 15296ISO 2503All current amendments available at time of purchase are included with the purchase of this document.
