Test Method Title

Standard Test Method for Permeability of Rocks by Flowing Air

Reference Number

ASTM D4525

Material

Rock

Test Property

Coefficient of Permeability

Description of Test

This test method is designed to measure the permeability to air of a small sample of rock. By extrapolation, this test method also determines an equivalent of the liquid permeability. This parameter is used to calculate the flow through rock of fluids subjected to a pressure differential.

Preferred Test Sample Size

Rock core specimens in the orientations dictated by the insitu conditions and test goals, for example, parallel and perpendicular to the bedding planes.

Number of Test Specimens

3 or more for each orientation

Test Specimen Size

Cylindrical specimens with length between 1.3 and 1.7 times the diameter.

Keywords
