Significance and Use

5.1  Hydrogen is delivered to mobile and stationary applications at maximum allowable working (MAWP) pressures up to 87.5 MPag (875 barg, 12 700 psig). The quality of hydrogen delivered is a significant factor in maximizing fuel cell efficiency and life span. Contamination can occur during the production of fuel cell feed gases, contaminating storage containers, station tubing, and fuel lines used for fuel delivery. Collection of a representative fuel sample without the introduction of contaminants even as low as parts per billion by volume (ppb(v)) per contaminant during collection is crucial for assessing the quality of fuel in real world applications and ensuring excessive fuel contaminants will not damage fuel cells or internal combustion engines.

5.2 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 feed gases. Many of the techniques used in this practice can be applied to lower pressure/lower purity gas streams.

Scope

1.1 This standard practice describes a sampling procedure of high pressure hydrogen at fueling stations operating at nominal working pressures (NWP) up to 70 megapascals (MPag) using a hydrogen quality sampling apparatus (HQSA).

1.2 This practice does not include the analysis of the acquired sample.

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 Practice D7650 and Test Method 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
