天然气加气站-为车辆加气的压缩天然气(CNG)站

[中文适用范围]： 本文件规定了为车辆加注压缩天然气（CNG）的加气站的设计、建造、运行、维护和检查的要求，包括设备、安全和控制装置，直至车辆的加注喷嘴。 本文件适用于根据当地适用的气体成分法规或ISO 13686定义的天然气供应的加气站。它也适用于满足这些要求的其他气体。 本文件也适用于加气站中天然气处于气态状态的部分，以及根据ISO 16924从液化天然气（LCNG）衍生并加注CNG的部分。 本文件涵盖了下游气体供应连接点（即CNG加气站管道与管网之间的分离点）的所有设备。本文件未定义加气站喷嘴。 本文件涵盖具有以下特征的加气站： — 慢充； — 快充； — 私人通道； — 公共通道（自助或辅助）； — 带有固定储气的加气站； — 带有移动储气（子站）的加气站； — 多燃料站。 本文件不适用于车对车传输或车辆加注设备（VRA）。 注：本文件基于进入加气站的气体已加臭的条件。对于未加臭的气体加气站，第10条包含了额外的安全要求。 [外文原描述]： This document specifies requirements for the design, construction, operation, maintenance and inspection of stations for fuelling compressed natural gas (CNG) to vehicles, including equipment, safety and control devices up to the fuelling nozzle to the vehicle. This document applies to fuelling stations supplied with natural gas as defined in local applicable gas composition regulations or ISO 13686. It also applies to other gases meeting these requirements. This document also applies to portions of a fuelling station where natural gas is in a gaseous state and dispensing CNG derived from liquefied natural gas (LCNG) according to ISO 16924. This document covers all equipment for downstream gas supply connection (i.e. point of separation between the CNG fuelling station piping and the pipeline network). Fuelling station nozzle are not defined in this document. This document covers fuelling stations with the following characteristics: — slow fill; — fast fill; — private access; — public access (self-service or assisted); — fuelling stations with fixed storage; — fuelling stations with mobile storage (daughter station); — multi-fuel stations. This document is not applicable to vehicle to vehicle transfer or vehicle refuelling appliances (VRA). NOTE This document is based on the condition that the gas entering the fuelling station is odorized. For unodorized gas fuelling stations, additional safety requirements are included in Clause 10.
