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

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Part 9:
Sampling for fuel quality analysis
WARNING — The use of sampling apparatuses, such as those described in the annexes to this
document, is associated with the safety risks associated with high pressure flammable gases. This
document explains the general concepts of how gaseous and particulate samples may be taken.
Sampling should be performed only by highly trained technicians experienced with the hazards of
high-pressure hydrogen.
1 Scope
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.

3.6
connector
matching parts (such as male and female parts) that can be put together to form a "connection" which
permits the transfer of fluids, electric power, or control signals
Note 1 to entry: Fitting (3.12) are a type of connector used in piping systems.
Note 2 to entry: Examples of connectors commonly used in hydrogen systems are as follows:
a) The fuelling nozzle (3.28) “connector” mates with the receptacle (3.36) “connector” on the vehicle to form the
connection for transfer of compressed hydrogen between the dispenser (3.7) and the vehicle, as defined in
ISO 17268 for this specific application;
b) The hose assemblies have connectors on each end that allow coupling to the hoses and connection to the piping
