Significance and Use
5.1 This sampling procedure is used to collect a particulate filter sample containing particulates 0.2 µm or larger in size to be used to measure the size and concentration of particulates in a gaseous fuel stream.
Scope
1.1 This practice is primarily for sampling particulates in gaseous fuels up to a nominal working pressure (NWP) of 70 MPa (10 152 psi) using an in-stream filter. This practice describes sampling apparatus design, operating procedures, and quality control procedures required to obtain the stated levels of precision and accuracy.
1.2 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
