Historical Standard: ASTM D4525-90(2001) Standard Test Method for Permeability of Rocks by Flowing Air
SUPERSEDED (see Active link, below)
ASTM D4525
1. Scope
1.1 This test method covers the determination of the coefficient of specific permeability for the flow of air through rocks. The procedure is to establish 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 nm (1.0 microdarcy), 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.
1.4 This standard does not purport to address the safety problems 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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
