Gaseous hydrogen — Fuelling stations — Part 9: Sampling for fuel quality analysis

ISO 19880-9:2024(Main)

This document outlines requirements for sampling from hydrogen fuelling stations for samples taken at the dispenser. The document defines the best practice for sampling at the nozzle of a hydrogen fuelling station as part of the fuelling station acceptance testing, and ongoing operation. Further, the document describes the minimum safety requirements for sampling. This document is targeted for the sampling from the hydrogen fuelling station dispenser. Many of the generic requirements within this document are applicable to sampling at other locations within the hydrogen fuelling station, which can be carried out for hydrogen quality assurance, see ISO 19880-8, however, further specific requirements that can be necessary for safe sampling are not addressed in this document. The intention of sampling hydrogen is to enable analysis against the requirements of ISO 14687, and by analytical methods validated by protocols described in ISO 21087. This document supersedes, and is an extension to, the guidance published in ISO 19880-1:2020, Annex K. NOTE Analytical methods are divided into on-line analyses and off-line analyses. On-line analysis allows for real time analysis at hydrogen stations and is not covered in this document.

Gaseous hydrogen — Fuelling protocols for hydrogen-fuelled vehicles — Part 1: Design and development process for fuelling protocols

ISO 19885-1:2024(Main)

This document addresses the design and development of fuelling protocols for compressed hydrogen gas dispensing to vehicles with compressed hydrogen storage of fuel. The document does not address dispensing of compressed hydrogen gas to vehicles with hydride-based hydrogen storage systems as well as the dispensing of liquefied or cryo-compressed hydrogen. This document is intended to be used for a wide range of applications including, but not limited to, the following: — light, medium, and heavy-duty road vehicles, — motor bicycles and tricycles, carts, and trailers, — off-road vehicles, — fork-lift and other industrial trucks, — rail locomotives and powered cars, — airplanes and drones, and — maritime ships, boats, and barges. This document applies to a wide spectrum of development situations ranging from companies developing a fuelling protocol for their specific products or applications to standards development organizations (SDOs) developing a consensus-based fuelling protocol for a broad segment of the industrial or commercial market. Additionally, combinations between the two extremes are possible, where, for example, companies start design and development as a way of defining a proposal for new work by an SDO to complete development and publish the document as a consensus-based standard (including technical justification for compliance to this document). This document defines requirements for the design and development of the fuelling protocols. These requirements can be integrated into the existing design and development processes to ensure that the fuelling protocol is fully verified and that the generated documentation is sufficient for the proper implementation and safe use of the fuelling protocols in dispensing systems for the targeted application. In addition to addressing the design and development of fuelling protocols for general applications, Annex A provides specific requirements and information relative to fuelling protocols for road vehicles at public fuelling stations based on ISO 19880-1.

Natural gas vehicles - Vehicle fuelling appliances

SIST EN 17278:2021(Main)

EN 17278:2021

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.
