Description of ASTM-D7634 2024

ASTM D7634-24

Active Standard: Standard Practice for Visualizing Particulate Sizes and Morphology of Particles Contained in Hydrogen Fuel by Microscopy




ASTM D7634

Scope

1.1 This practice is intended for visualizing and measuring the sizes and morphology of particulates in hydrogen used as a fuel for fuel cell or internal combustion engine powered vehicles. This test method describes procedures required to obtain size and morphology data of known quality. This test method can be applied to other gaseous samples requiring determination of particulate sizes and morphology provided the user’s data quality objectives are satisfied.

1.2 This practice describes procedures required to obtain size and morphology data of known quality.

1.3 This practice may be applied to other gaseous samples requiring the determination of particulate sizes and morphology provided the user’s data quality objectives are satisfied.

1.4 Mention of trade names in the standard does not constitute endorsement or recommendation. Other manufacturers of equipment, software or equipment models may be used.

1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.6 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.

1.7 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.
