This document specifies the validation protocol of analytical methods used for ensuring the quality of the gaseous hydrogen quality at hydrogen distribution bases and hydrogen fueling stations for PEM fuel cells for road vehicles. Recommendation on calculation of uncertainty budget is also given in this document.

This protocol is established mainly for analysis done in laboratories after the sampling of hydrogen either at hydrogen distribution bases or at hydrogen refueling stations. The specific requirements for on-line monitoring are not covered by this document.

A list of suitable analytical techniques used to measure each impurity in hydrogen, according to the specification defined by ISO 14687, is also given in this standard.

Moreover, recommendations for keeping the integrity of the sample are also given in order to ensure the quality of the measurement.

Guideline for reporting the analytical results is also included in this standard.
