Full title and description

ISO 16924:2016 — Natural gas fuelling stations — LNG stations for fuelling vehicles. This International Standard specifies requirements for the design, construction, operation, maintenance and inspection of stations that fuel road vehicles with liquefied natural gas (LNG), including stations that use LNG onsite to produce compressed natural gas (LCNG).

Abstract

ISO 16924:2016 sets out safety, equipment and control requirements covering LNG and liquefied methane‑rich gases at fuelling stations. It addresses design, construction, operation, maintenance and inspection of LNG fuelling stations and LCNG fuelling stations and identifies the parts of the fuelling system that are within its scope.

General information

• Status: Withdrawn (was published as an International Standard; later revised).
• Publication date: December 2016 (Edition 1, 2016-12).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: Petroleum products and natural gas handling equipment — ICS 75.200.
• Edition / version: Edition 1 (2016).
• Number of pages: 77 pages (as published in 2016; subsequent national/adopted versions may show slightly different pagination).

Scope

ISO 16924:2016 applies to fuelling stations receiving LNG (and other liquefied methane‑rich gases that meet local composition or ISO 13686 requirements) with private or public access, metered or non‑metered dispensing, fixed or mobile storage, movable or mobile fuelling stations and multi‑fuel stations. The standard covers equipment from the LNG storage tank filling/unloading connection up to the vehicle fuelling nozzle, but the storage tank filling/unloading connection itself and the vehicle fuelling nozzle are excluded from the document's technical requirements.

Key topics and requirements

• Design principles and layout for LNG fuelling stations (including site equipment and segregation of hazardous areas).
• Safety systems and protection measures (overpressure protection, electrical safety, static electricity control, emergency shutdowns and leak detection).
• Operational requirements: procedures for filling, dispensing, monitoring and control systems for safe station operation.
• Maintenance and inspection: routine and periodic inspection, testing and maintenance regimes to ensure continuing safe operation.
• Requirements for LCNG stations (where LNG is used onsite to supply compressed natural gas), and interfaces with dedicated CNG requirements (note: ISO 16923 addresses specific CNG equipment).
• Environmental and operability considerations relevant to LNG handling and vapour management.

Typical use and users

Used by designers and engineers of alternative‑fuel infrastructure, LNG station owners and operators, site safety and maintenance teams, fuel equipment manufacturers, certification and inspection bodies, and regulators setting national or regional requirements for LNG fuelling stations. National standards bodies and industry stakeholders also use the standard when adopting or harmonizing regional versions (for example EN/BSI adoptions).

Related standards

Key related documents include ISO 16923 (natural gas fuelling stations — CNG stations) and ISO 13686 (gas quality requirements referenced for methane‑rich gases). Regional/adopted versions and companion standards for alternative fuels infrastructure and equipment safety are commonly referenced alongside ISO 16924.

FAQ

Q: What is this standard?

A: ISO 16924:2016 is an ISO International Standard that defined requirements for the design, construction, operation, maintenance and inspection of LNG fuelling stations for road vehicles (including LCNG configurations).

Q: What does it cover?

A: It covers station design and equipment, safety and control devices, operational procedures and maintenance/inspection regimes for LNG (and liquefied methane‑rich gases) fuelling stations from the station storage tank filling/unloading connection up to the vehicle fuelling nozzle (with the tank filling connection and vehicle nozzle themselves excluded).

Q: Who typically uses it?

A: Engineers and designers of fuelling stations, station owners and operators, equipment manufacturers, inspection and certification bodies, and regulators or standards adopters are the primary users.

Q: Is it current or superseded?

A: ISO 16924:2016 has been withdrawn and replaced by a later edition, ISO 16924:2026 (Edition 2, published January 2026). For current requirements users should refer to the 2026 edition or their national/adopted version.

Q: Is it part of a series?

A: It is part of a family of ISO standards on natural‑gas fuelling stations; most notably ISO 16923 (CNG stations) covers complementary CNG equipment and requirements referenced by ISO 16924. The standards are developed under ISO/TC 340 (natural gas and hydrogen fuelling stations).

Q: What are the key keywords?

A: LNG, LCNG, natural gas fuelling stations, safety, dispensing, maintenance, inspection, ISO 16924, alternative fuels infrastructure.
