Natural gas fuelling stations - LNG stations for fuelling vehicles (ISO/DIS 16924:2024)

ISO 16924:2016 specifies the design, construction, operation, maintenance and inspection of stations for fuelling liquefied natural gas (LNG) to vehicles, including equipment, safety and control devices.
ISO 16924:2016 also specifies the design, construction, operation, maintenance and inspection of fuelling stations for using LNG as an onsite source for fuelling CNG to vehicles (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.
ISO 16924:2016 is applicable to fuelling stations receiving LNG and other liquefied methane-rich gases that comply with local applicable gas composition regulation or with the gas quality requirements of ISO 13686.
ISO 16924:2016 includes all equipment from the LNG storage tank filling connection up to the fuelling nozzle on the vehicle. The LNG storage tank filling connection itself and the vehicle fuelling nozzle are not covered in this document.
ISO 16924:2016 includes 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.

Stations-service de gaz naturel - Stations GNL pour le ravitaillement de véhicules (ISO/DIS 16924:2024)

L'ISO 16924:2016 spécifie la conception, la construction, l'exploitation, la maintenance et l'inspection des stations-service de gaz naturel liquéfié (GNL) pour véhicules, dont les équipements et les dispositifs de sécurité et de contrôle.
L'ISO 16924:2016 spécifie également la conception, la construction, l'exploitation, la maintenance et l'inspection des stations-service de gaz naturel liquéfié (GNL) servant également de site de ravitaillement des véhicules en gaz naturel comprimé (GNC), appelées stations-service de GNLC (gaz naturel liquéfié/comprimé), en couvrant les dispositifs de sécurité et de contrôle des stations et les équipements propres aux stations-service GNLC.
NOTE       Les équipements propres aux stations de GNC sont couverts par l'ISO 16923.
L'ISO 16924:2016 s'applique aux stations-service ravitaillées en GNL et autres gaz liquéfiés riches en méthane conformes à la réglementation locale applicable aux compositions gazeuses ou aux exigences en matière de qualité des gaz de l'ISO 13686.
L'ISO 16924:2016 couvre tous les équipements, du connecteur pour le dépotage de GNL dans réservoir de stockage GNL au pistolet de ravitaillement destiné aux réservoirs des véhicules. Le connecteur de ravitaillement du réservoir et le pistolet de ravitaillement des véhicules à proprement dits ne sont pas couverts par ce document.
L'ISO 16924:2016 couvre toutes les stations-service présentant les caractéristiques suivantes:
-      accès privé;
-      accès public (self-service ou avec assistance);
-      borne de distribution de carburant avec ou sans compteur;
-      stations-service avec stockage de GNL fixe;
-      stations-service avec stockage mobile de GNL;
-      stations-service transportables;
-      stations-service mobiles;
-      stations-service multi-carburants.
