标准范围
本文件规定了用于气体传输、分配和安装的高压控制装置（以下简称控制装置）的一般安全、结构、性能、测试和文件要求。本文件适用于操作压力大于500 kPa（5 bar）且不超过10 MPa（100 bar）且标称尺寸不超过DN 400的控制装置，用于商业、工业设施（包括燃气基础设施）中的天然气、人造气体、生物甲烷或液化石油气（LPG）等燃料气体。本文件中给出的试验方法旨在用于产品型式试验、常规试验和批次监督试验。本文件不适用于:-控制安装在家用燃气表下游的家用燃气器具的上游/上游/上游；-设计为申报的最大容量≤200立方米/小时（正常条件）和申报的最大入口压力≤500千帕（5巴）的控制装置，将被纳入服务管线（从气体基础设施中的主管道到气体输送点的管道）中使用的压力控制系统；-工业过程控制阀，例如IEC 60534；-在侵蚀性/酸性气体环境（含有水和H2S的气体环境被认为是酸性的）或严重腐蚀性条件下使用的控制；-如果未提供附加信息（例如污染物、液体等），则在使用可再生能源（例如氢气含量超过10%的H2NG）和/或废气（例如沼气等）的条件下进行控制。
This document specifies generic safety, constructional, performance, testing and documentation requirements for high pressure controls for use in gas transmission, distribution and installations (hereafter referred to as controls).This document is applicable to controls with operating pressures greater than 500 kPa (5 bar) and up to and including 10 MPa (100 bar) and nominal size up to DN 400 for use with fuel gases as natural gas, manufactured gas, biomethane or liquefied petroleum gas (LPG) in commercial, industrial installations, including fuel gas infrastructures.The test methods given in this document are intended for product type test, routine tests and batch surveillance tests.This document is not applicable to:— controls upstream from/on/in domestic gas-consuming appliances which are installed downstream of domestic gas meters;— controls designed with declared maximum capacity ≤200 m3/h (normal conditions) and declared maximum inlet pressure ≤500 kPa (5 bar), to be incorporated into pressure control systems used in service lines (pipework from the main pipework in a gas infrastructure to the point of delivery of the gas);— industrial process control valves, such as IEC 60534;— controls used in aggressive/sour gas environments (gas environments containing water and H2S are considered sour) or severely corrosive conditions;— controls in service conditions with renewables (e.g. H2NG with hydrogen more than 10 %) and/or waste gases (e.g. biogas, etc.), if additional information is not provided (e.g. contaminant, liquid, etc.).
