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 documents 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).

Introduction
This document was developed to specify how the quality of gaseous hydrogen fuel for road vehicles
which use PEM fuel cells can be assured. 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 measure the level of contaminants found in the gaseous hydrogen fuel.
