This document covers the design and manufacturing, installation and testing, operation and maintenance for vehicle fuelling appliances (VFAs) – the assemblies of the pressure equipment with limited technical parameters, intended for the non-commercial fuelling of natural gas vehicles (NGVs) with compressed natural gas (CNG).
This document is applicable to VFAs supplied with natural gas as defined in local applicable gas composition regulations or EN 16723-2, or with other gases meeting these requirements including biomethane, upgraded coal-bed methane (CBM) and gas from liquefied natural gas (LNG) vaporizer (on-site or off-site).
In case of combination of the certified VFA assembly with additional equipment, such as external storage and/or dispenser, EN ISO 16923 applies to the new assembly - the certified VFA assembly with added external equipment.
In case of combinations of interconnected VFA assemblies, EN ISO 16923 applies to the whole new assembly of the certified VFA assemblies.

This document specifies cleanliness assessment procedures for evaluating the amount of debris found within the clean side of diesel fuel injection assemblies, which could lead to a reduction in the system’s operational effectiveness. While other International Standards, e.g. ISO 16232, relate to cleanliness of components used in road vehicle fluid circuits, this document is focused on diesel fuel injection assemblies as supplied to diesel engine manufacturers or the service market.

This document specifies tests and requirements for the differential pressure fuel content gauge, a liquefied natural gas fuel system component intended for use on the types of motor vehicles defined in ISOÂ 3833. This document is not applicable to the following: a) fuel containers; b) stationary gas engines; c) container mounting hardware; d) electronic fuel management; e) refuelling receptacles. It is recognized that miscellaneous components not specifically covered herein can be examined to meet the criteria of this document and tested according to the appropriate functional tests. All references to pressure in this document are to be considered gauge pressures unless otherwise specified. This document is based upon a maximum working pressure for natural gas as fuel of 1,6 MPa (16 bar1). Â Other working pressures can be accommodated by adjusting the pressure by the appropriate factor (ratio). For example, a 2 MPa (20 bar) working pressure system will require pressures to be multiplied by 1,25. Â 11 bar = 0,1 MPa = 105 Pa; 1 MPa = 1 N/mm2.

This document specifies cleanliness assessment procedures for evaluating the amount of debris present on the clean side of the constituent parts of high-pressure gasoline direct fuel injection systems. The presence of such debris could lead to a reduction in the system's operational performance. While other International Standards (e.g. ISO 16232) relate to the cleanliness of different types of components used in road vehicle fluid circuits, this document focuses on the special procedures applied for the components of gasoline direct fuel injection systems.

This document defines the minimum design, installation, commissioning, operation, inspection and maintenance requirements, for the safety, and, where appropriate, for the performance of public and non-public fuelling stations that dispense gaseous hydrogen to light duty road vehicles (e.g. fuel cell electric vehicles). This document is not applicable to the dispensing of cryogenic hydrogen, or hydrogen to metal hydride applications. Since this document is intended to provide minimum requirements for fuelling stations, manufacturers can take additional safety precautions as determined by a risk management methodology to address potential safety risks of specific designs and applications. While this document is targeted for the fuelling of light duty hydrogen road vehicles, requirements and guidance for fuelling medium and heavy duty road vehicles (e.g. buses, trucks) are also covered. Many of the generic requirements within this document are applicable to fuelling stations for other hydrogen applications, including but not limited to the following: — fuelling stations for motorcycles, fork-lift trucks, trams, trains, fluvial and marine applications; — fuelling stations with indoor dispensing; — residential applications to fuel land vehicles; — mobile fuelling stations; and — non-public demonstration fuelling stations. However, further specific requirements that can be necessary for the safe operation of such fuelling stations are not addressed in this document. This document provides requirements for and guidance on the following elements of a fuelling station (see Figure 1 and Figure 2): — hydrogen production/delivery system: — delivery of hydrogen by pipeline, trucked in gaseous and/or liquid hydrogen, or metal hydride storage trailers; — on-site hydrogen generators using water electrolysis process or hydrogen generators using fuel processing technologies; — liquid hydrogen storage; — hydrogen purification systems, as applicable; — compression: — gaseous hydrogen compression; — pumps and vaporizers; — gaseous hydrogen buffer storage; — pre-cooling device; — gaseous hydrogen dispensing systems.

This document specifies the requirements for wire or textile reinforced hoses and hose assemblies suitable for dispensing hydrogen up to 70 MPa nominal working pressure, in the operating temperature range of −40 °C to 65 °C. This document contains safety requirements for material, design, manufacture and testing of gaseous hydrogen hose and hose assemblies for hydrogen fuelling stations. Hoses and hose assemblies excluded from the scope of this document are the following: 1) those used as part of a vehicle high pressure on-board fuel storage system, 2) those used as part of a vehicle low pressure fuel delivery system, and 3) flexible metal hoses. NOTE 1 This document was developed primarily for hoses and hose assemblies for dispensing high pressure hydrogen from refuelling dispensers to hydrogen vehicles. Requirements for hoses used to deliver hydrogen from a transportable vessel (e.g. trailer) into a buffer storage of a station are addressed in ISO 16964. NOTE 2 Hose assemblies include the hose with connectors on each end (see Figure 1). Each connector has two basic functional elements that are addressed as described below: 1) Coupling to hose. This function is defined by requirements and verified (along with the hose itself) by performance-based tests in this document. 2) Fitting for transition and connection to the piping system or equipment. This function is addressed by reference to appropriate hydrogen equipment standards and piping codes.
