及以下气体输送、分配和安装用气体压力安全和控制装置第2部分:气体压力调节器

[中文适用范围]： 本文件规定了气体压力调节器的安全、构造、性能、测试和文件要求，用于燃气输配和分配装置（以下简称调节器）。本文件适用于额定工作压力大于500 kPa且不超过10 MPa（100 bar）且公称直径DN 400及以下的用于燃料气体（如天然气、人工煤气、生物甲烷或液化石油气（LPG））的压力调节器。本文件适用于：——旨在用于产品型测试、常规测试和产品质量监控测试的方法；——不依赖任何外部电源作为控制能源，以管道气体为控制能量来源的调节器；——集成在同一主体上的第二个调节器，用作监控装置，符合本文件要求；——集成安全关闭装置（SSD）的调节器，符合ISO 23555-3的要求；——包含蠕变（排气） relief装置和/或排气限制器的调节器，符合本文件要求。本文件不适用于：——安装在家庭用气设备之前的调节器，安装在家庭煤气表之后；——设计用于服务于服务管道（从燃气基础设施的主要管道到供气点的管道系统）的压力控制系统的调节器，其 declared 流量 ≤ 200 m3/h，在正常条件下 declared 进口压力 ≤ 500 kPa（5 bar）；——工业过程控制阀，如IEC 60534（所有部分）；——在含水和 H2S（酸性气体环境）或严重腐蚀条件下使用的调节器；——用于可再生资源（例如H2NG中氢含量超过10%）和/或废气（例如生物气等）的运行条件下的调节器，如果未提供额外信息（例如污染物、液体等）。 [外文原描述]： This document specifies safety, constructional, performance, testing and documentation requirements for gas pressure regulators for use in gas transmission and distribution installations (hereafter referred to as regulators). This document is applicable to regulators with operating pressures greater than 500 kPa and up to and including 10 MPa (100 bar) and nominal diameters up to DN 400 for use with fuel gases as natural gas, manufactured gas, biomethane or liquefied petroleum gas (LPG). This document is applicable to: — test methods which are intended for product type test, routine tests and product surveillance tests; — regulators which use the pipeline gas as a source of control energy unassisted by any external power source; — regulators integrating on the same body a second regulator, used as monitor, complying with the requirements in this document; — regulators integrating a safety shut off device (SSD) according to ISO 23555-3; — regulators incorporating a creep (venting) relief device and/or a vent limiter complying with the requirements in this document. This document does not apply to: — regulators upstream from/on/in domestic gas‑consuming appliances which are installed downstream of domestic gas meters; — regulators designed 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) with declared volumetric flow rate ≤ 200 m 3 /h at normal conditions and declared inlet pressure ≤ 500 kPa (5 bar); — industrial process control valves, such as IEC 60534 (all parts); — regulators used in aggressive/sour gas environments (gas environments containing water and H2S are considered sour) or severely corrosive conditions; — regulators 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.).
