1.1 This test method covers the determination of the coefficient of specific permeability for the flow of air through rocks. The procedure establishes representative values of the coefficient of permeability of rocks or well-indurated soils.
1.2 This test method is limited to permeability values greater than 0.9869 pm2 (1.0 picodarcy), and is limited to rocks free of oil or unctuous matter.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.4 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.
