标准摘要
[中文适用范围]： 本文件规定了与工业气体分配管道连接的线压力调节器的要求，包括：压缩气体和二氧化碳（最大6 MPa (60 bar)）；乙炔（150 kPa (1.5 bar)）；液化石油气；以及甲基丙烯-丁二烯混合物。这些设备用于焊接、切割和其他相关工艺。 本文件不适用于直接连接到气瓶或捆绑装置上的压力调节器，此类调节器分别在ISO 2503和ISO 7291中规定。 [外文原描述]： This document specifies requirements for line pressure regulators and line pressure regulators with flow-metering devices to be connected to industrial gas distribution pipelines of: — compressed gases and carbon dioxide up to 6 MPa (60 bar); — acetylene up to 150 kPa (1,5 bar); — liquefied petroleum gases (LPG); — methylacetylene-propadiene mixtures (MPS); for use in welding, cutting and allied processes. This document does not apply to pressure regulators intended for direct use on cylinders or bundles, such regulators are addressed in ISO 2503 or ISO 7291, respectively. NOTE Where there is no risk of ambiguity, both line pressure regulators and line pressure regulators with flow-metering devices are addressed with the collective term ‘pressure regulators’.
