This document specifies the validation protocol of analytical methods used for ensuring the quality
of the gaseous hydrogen (H2 ) at hydrogen distribution bases and hydrogen fuelling stations for road
vehicles using proton exchange membrane (PEM) fuel cells. It also gives recommendations on the
calculation of an uncertainty budget for the amount fraction.
This document is established mainly for analysis done in laboratories after the sampling of hydrogen
either at hydrogen distribution bases or at hydrogen refuelling stations. The specific requirements for
on-line monitoring are not covered by this document.
This document gives a list of suitable analytical techniques used to measure each impurity in hydrogen,
according to the specification of hydrogen grade D defined by ISO 14687:— .
Moreover, recommendations for keeping the integrity of the sample are also given in order to ensure
the quality of the measurement. It also includes the requirements for reporting the analytical results.
