ISO 16923:2016涵盖了向车辆（包括设备，安全和控制设备）供应压缩天然气（CNG）的车站的设计，建造，操作，检查和维护。 根据ISO 16924，ISO 16923:2016也适用于天然气处于气态的加气站的一部分，并分配来自液化天然气（LCNG）的CNG。 ISO 16923:2016适用于按照当地适用的气体成分法规或ISO 13686定义的供应天然气的加气站。它也适用于其他符合这些要求的气体，包括生物甲烷，升级的煤层气（CBM）和来自LNG的天然气供应汽化（现场或非现场）。 ISO 16923:2016包括下游供气连接的所有设备（即CNG加油站管道和管网之间的分离点）。本文档中未定义加油站喷嘴。 ISO 16923:2016涵盖了具有以下特征的加油站: - 缓慢填充; - 快速填充; - 私人访问; - 公共访问（自助服务或辅助）; - 具有固定存储的加油站; - 带移动存储的加油站（女儿站）; - 多燃料站。 ISO 16923:2016不适用于国内CNG加油设备无缓冲存储。 注:ISO 16923:2016是基于进入加油站的气体被加臭的条件。对于无味的气体加气站，第10章包括附加的安全要求。

ISO 16923:2016 covers the design, construction, operation, inspection and maintenance of stations for fuelling compressed natural gas (CNG) to vehicles, including equipment, safety and control devices. ISO 16923:2016 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. ISO 16923:2016 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 including biomethane, upgraded coal-bed methane (CBM) and gas supplies coming from LNG vaporization (on-site or off-site). ISO 16923:2016 includes all equipment for downstream gas supply connection (i.e. point of separation between the CNG fuelling station piping and the pipeline network). Fuelling station nozzles are not defined in this document. ISO 16923:2016 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. ISO 16923:2016 is not applicable to domestic CNG fuelling devices without buffer storage. NOTE ISO 16923:2016 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.
