Publication date:   Mar 17, 2026

Scope

This document specifies requirements for the design, construction, operation, maintenance and inspection of stations for fuelling liquefied natural gas (LNG) to vehicles, including equipment, safety and control devices. This document also specifies the design, construction, operation, maintenance and inspection of fuelling stations using LNG as an onsite source for supplying compressed natural gas (CNG) to vehicles, commonly referred to as liquefied-to-compressed natural gas (LCNG) fuelling stations, including safety and control devices of the station and specific LCNG fuelling station equipment.
NOTE            Specific CNG equipment is dealt with in ISO 16923.
This document is applicable to fuelling stations receiving LNG and other liquefied methane-rich gases such as bio LNG which comply with local applicable gas composition regulations or with the gas quality requirements of ISO 13686.
This document covers all equipment from the LNG storage tank unloading connection up to (but not including) the fuelling nozzle on the vehicle. The LNG storage tank unloading connection itself and the vehicle fuelling nozzle are not covered in this document.
This document applies to fuelling stations having the following characteristics:

private access;
public access (self-service or assisted);
metered dispensing and non-metered dispensing;
fuelling stations with fixed LNG storage;
fuelling stations with mobile LNG storage;
movable fuelling stations;
mobile fuelling stations;
multi-fuel stations.

This document does not apply to:
