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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee TC 197, Hydrogen technologies.
This second edition cancels and replaces the first edition (ISO 19880-8:2019), which has been technically
revised. It also incorporates the Amendment ISO 19880-8:2019/AMD 1:2021.
The main changes are as follows:
— aligned with the revision of ISO 14687, in particular the change in the specifications of Grade D, the
indicators required for risk assessment have been mainly changed;
— due to the change in the document structure of ISO 14687, the rationale for each of the ISO 14687, Grade
D specifications has been moved to ISO 14687.

Introduction
This document was developed to specify how the quality of gaseous hydrogen fuel for road vehicles which
use proton exchange membrane (PEM) fuel cells can be assured to meet the impurity levels in Grade D of
ISO 14687. The document discusses hydrogen quality control approaches for routine and non-routine
conditions, as well as quality assurance plans. It is based upon best practices and experience from the
gaseous fuels and automotive industry. ISO 21087 describes the requirements for analytical methods to
[1]
measure the level of contaminants in ISO 14687, Grade D. ISO 19880-9 outlines requirements for sampling
from hydrogen refuelling stations for samples taken at the dispenser.
