Natural gas fuelling stations - CNG stations for fuelling vehicles (ISO/DIS 16923:2024)

Natural gas fuelling stations - CNG stations for fuelling vehicles (ISO/DIS 16923:2024)

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.

Stations-service de gaz naturel - Stations GNC pour le ravitaillement de véhicules (ISO/DIS 16923:2024)

L'ISO 16923:2016 traite de la conception, la construction, l'exploitation, l'inspection et la maintenance des stations de ravitaillement au gaz naturel comprimé (GNC) pour véhicules, dont les appareils et les dispositifs de sécurité et de contrôle.
L'ISO 16923:2016 s'applique également aux parties d'une station-service où le gaz naturel se trouve à l'état gazeux et où le GNC dérivé d'un gaz naturel liquéfié (GNCL) est distribué conformément à l'ISO 16924.
L'ISO 16923:2016 s'applique aux stations-service alimentées par gaz naturel tel que défini par les règlements locaux applicables relatifs à la composition des gaz ou par l'ISO 13686. Elle s'applique également à d'autres gaz satisfaisant à ces exigences tels que le biométhane, le méthane de houille (MH) valorisé et les gaz provenant de la vaporisation de GNL (sur ou hors site).
L'ISO 16923:2016 couvre tous les appareils en aval de la connexion d'alimentation en gaz (c'est-à-dire le point de séparation entre les conduites de la station-service GNC et le réseau de canalisations). Les pistolets de distribution des stations-service ne sont pas définis dans ce document.
L'ISO 16923:2016 comprend les stations-service avec les caractéristiques suivantes:
- remplissage lent;
- remplissage rapide;
- accès privé;
- accès public (self-service ou avec assistance);
- stations-service avec stockage fixe;
- stations-service avec stockage mobile (station secondaire);
- stations multi-carburants.
L'ISO 16923:2016 ne s'applique pas aux dispositifs domestiques de ravitaillement de GNC sans stockage tampon.
NOTE       L'ISO 16923:2016 repose sur la condition que les gaz fournis à la station-service sont odorisés. Pour les stations-service utilisant des gaz non odorisés, des exigences de sécurité supplémentaires sont spécifiées à l'Article 10.

Gas infrastructure - Pipelines for maximum operating pressure over 16 bar - Functional requirements
EN 1594:2024

This EU standard is applicable for transporting gas via onshore high pressure steel pipeline infrastructures where:
-   onshore: from the point where the pipeline first crosses what is normally accepted as battery limit between onshore and offshore and not located within commercial or industrial premises as an integral part of the industrial process on these premises except for any pipelines and facilities supplying such premises. This European Standard also applies to a pipeline system with a starting point onshore, also when parts of the pipeline system on the mainland subsequently cross fjords, lakes etc.
-   high pressure: gas with a maximum operating pressure over 16 bar and a design temperature between −40 °C and 120 °C
-   steel pipeline infrastructure: a steel pipeline infrastructure consists of pipeline components such as pipes, valves, couplings and other equipment. Pipeline components in scope are restricted to components made of unalloyed or low alloyed carbon steel and joined by welds, flanges or mechanical couplings.
-   gas: non-toxic and non-corrosive natural gas, biomethane gas, hydrogen gas and mixtures of these gasses where technical evaluation has ensured that operating conditions or constituents or properties of the gas do not affect the safe operation of the pipeline.
Gas infrastructures covered by this European Standard begin after the gas producer's metering station. The functional demarcation of the pipeline system within a plant area will be determined from case to case. Generally speaking, this will be directly after the first isolating valve of the metering installation.
This European Standard also describes the mechanical requirements for pipework in stations with a maximum operating pressure greater than 16 bar.
Welding requirements are described in EN 12732. Functional requirements for stations are given in EN 1776, EN 1918-5, EN 12186, and EN 12583. Requirements for safety management and pipeline integrity management are given in EN 17649.
This European Standard specifies common basic principles for gas infrastructures. Users of this European Standard should be aware that there may exist more detailed national standards and codes of practice in the CEN member countries.
This European Standard is intended to be applied in association with these national standards and/or codes of practice setting out the above mentioned principles.
This European Standard does not apply to existing pipelines, in use prior to the publication of this European Standard, nor to modifications to existing pipelines, except for the adaptation of the pipelines for the use of hydrogen and admixtures with hydrogen.
In the event of conflicts in terms of more restrictive requirements in the national legislation/regulation with the requirements of this European Standard, the national legislation/regulation takes precedence as illustrated in CEN/TR 13737 (all parts).
Reference is made in this European Standard to relevant European and other recognised standards for products used to construct and operate gas infrastructures.
