标准摘要
[中文适用范围]: 本国际标准规定了焊接、切割和相关工艺中使用的歧管系统压力调节器的要求和测试方法: a) 压缩气体高达 30 MPa1) (300 bar); b) 溶解乙炔; c) 液化石油气(LPG); d) 甲基乙炔-丙二烯混合物(MPS); e) 二氧化碳(CO2)。 它不适用于 ISO 2503[2] 中定义的直接安装在气瓶上的压力调节器。 [外文原描述]: ISO 7291:2010 specifies requirements and test methods for pressure regulators in manifold systems used in welding, cutting, and allied processes for: a) compressed gases up to 30 MPa (300 bar); b) dissolved acetylene; c) liquefied petroleum gases (LPG); d) methylacetylene‑propadiene‑mixtures (MPS); e) carbon dioxide (CO 2 ). It is not applicable to pressure regulators fitted directly to the gas cylinders, as defined in ISO 2503.
