Standard Test Method for Saturated Water Permeability of Granular Drainage Media [Falling-Head Method] for Green Roof Systems
standard by ASTM International, 08/15/2005
1.1 This test method covers a procedure for determining the water permeability of coarse granular materials used in the drainage layers of green roof systems.
1.2 This test method addresses water permeability under the low-head conditions that typify horizontal flow in green roof applications.
1.3 This test method is suitable for coarse-grained materials with 100 % of the material retained on the U.S. #8 (2.25 mm) sieve. It is not suitable for finer-grained materials.
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 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 to determine the applicability of regulatory limitations prior to use.
