    Significance and Use

       Hydrogen is delivered to fuel cell powered automotive vehicles and stationary appliances at pressures up to 87.5 MPa. The quality of hydrogen delivered is a significant factor in maximizing fuel cell efficiency and life span. Contamination can arise during the production of fuel cell feed gases, storage containers, station tubing and fuel lines up to the nozzle used for fuel delivery. Collection of a representative fuel sample without the introduction of contamination even as low as parts-per-billion (ppb) per contaminant during collection is crucial for assessing the quality of fuel in real world applications.

    This practice is intended for application to high pressure, high purity hydrogen; however, the apparatus design and sampling techniques may be applicable to collection of other fuel cell supply gases. Many of the techniques used in this practice can be applied to lower pressure/lower purity gas streams.

    1. Scope

    1.1 This practice describes a hydrogen quality sampling apparatus (HQSA) and a procedure for the sampling of high pressure hydrogen at fueling nozzles of 35 or 70 Mega Pascal (MPa) fueling stations.

    1.2 This practice does not include the analysis of the acquired sample. Applicable ASTM standards include but are not limited to test methods referenced in Section 2 of this practice.

    1.3 This practice is not intended for sampling and measuring particulate matter in high pressure hydrogen. For procedures on sampling and measuring particulate matter see ASTM D7650 and D7651.

    1.4 The values stated in SI units are standard. The values stated in inch-pounds are for information only.

    1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
