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:—1). 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.Cross References:ISO 14687ASTM D7652JIS K 0512ISO 12963JIS B 7956ASTM D7649ISO 19880-8ASTM D7941ISO 6143ISO 19880-1JIS K 0114JIS K 0303ISO 3534 (all parts)ISO 21748JIS K 0127ISO/IEC 17025:2017ISO 6142-1ASTM D7653ISO 19229ISO 6145 (all parts)ASTM D7675ASTM D7892ISO 5725 (all parts)ISO/TR 15916ASTM D7607All current amendments available at time of purchase are included with the purchase of this document.
