Overview - ISO 16924:2016 (ISO 16924:2016)
ISO 16924:2016 (identical to ISO 16924:2016) is the international standard for natural gas fuelling stations that use liquefied natural gas (LNG) to fuel vehicles. It specifies requirements for the design, construction, operation, maintenance and inspection of LNG fuelling stations and of LCNG fuelling stations (where LNG is used onsite to produce compressed natural gas). The standard covers equipment, safety and control devices from the LNG storage tank filling connection up to the vehicle fuelling nozzle (the tank filling connection itself and the vehicle nozzle are excluded). It applies to LNG and other liquefied methane‑rich gases that comply with local gas composition regulations or the gas quality requirements of ISO 13686.
Key Topics and Technical Requirements
ISO 16924 organizes technical content around safe, operational and environmental aspects of LNG fuelling stations. Major topics include:
- Risk management: hazard and risk assessment, protection against overpressure and static electricity.
- Fire and explosion protection: hazardous area classification, ignition source control and fire‑fighting arrangements.
- General design requirements: design philosophy, buildings and civil works, installation and construction practices.
- Site layout and security: separation distances, traffic management, access (private/public), and security measures.
- Fuel supply systems: requirements for filling connectors, prevention of overfilling and backflow, bleed and drain connections, and LNG tanker interfaces.
- Storage: LNG storage tank design, safety requirements and installation guidance for fixed and mobile storage.
- Pumps, compressors and dispensers: selection, installation and safety for centrifugal/reciprocating pumps, dispensers, hoses, breakaway systems and metering.
- Vaporizers and heaters: vaporization options (ambient air, electric, water bath, fired) and design considerations.
- Odorization, instrumentation and control: monitoring, alarms and station control systems.
- Maintenance and inspection: operational checks, inspection intervals and documentation.
Practical Applications & Who Uses ISO 16924
This standard is used by professionals involved in the lifecycle of LNG and LCNG vehicle fuelling infrastructure:
- Station designers and engineering consultancies
- Equipment manufacturers (pumps, dispensers, vaporizers)
- Fuel station operators and fleet owners (public, private, mobile/movable)
- Safety and compliance managers, inspectors and regulators
- Contractors for construction, commissioning and maintenance
ISO 16924 helps ensure safe, compliant LNG refuelling stations that support fleet electrification alternatives, heavy vehicle decarbonization and multi‑fuel station deployments.

ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

nationaux de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est
en général confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l’ISO participent également aux travaux.
L’ISO collabore étroitement avec la Commission électrotechnique internationale (IEC) en ce qui
concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier de prendre note des différents
critères d’approbation requis pour les différents types de documents ISO. Le présent document a été
rédigé conformément aux règles de rédaction données dans les Directives ISO/IEC, Partie 2 (voir www.
