标准摘要
[中文适用范围]： 本文件规定了燃气和氧气或压缩空气安全装置的一般要求和测试，该安全装置包含用于歧管、钢瓶和/或管道出口调节器下游以及用于焊接、切割和相关工艺的吹管上游的阻火器。 本文件没有指定这些设备在气体系统中的位置。 本文件不适用于未包含阻火器的安全装置，涵盖范围 本文件不适用于将包含阻火器的安全装置用于预混合氧气/燃料或空气/燃气供应系统的应用，例如气体混合器的下游或通过电解水分解产生氢气/氧气混合物的发生器。 [外文原描述]： ISO 5175-1:2017 specifies the general requirements and tests for safety devices for fuel gases and oxygen or compressed air incorporating a flame (flashback) arrestor used downstream of manifold, cylinder and/or pipeline outlet regulators, and upstream of blowpipes for welding, cutting and allied processes. ISO 5175-1:2017 does not specify the location of these devices in the gas system. ISO 5175-1:2017 is not applicable to safety devices not incorporating a flame arrestor, covered by ISO 5175‑2. ISO 5175-1:2017 does not apply to the use of safety devices incorporating flame arrestors for applications with premixed oxy/fuel or air/fuel gas supply systems, e.g. downstream of gas mixers or a generator to produce hydrogen/oxygen mixture by electrolytic decomposition of water.
