scope:

1.1 This test method covers a procedure for determining the water permeability of coarse granular materials used in the drainage layers of vegetative (green) roof systems.

1.2 This test method addresses water permeability under the low-head conditions that typify horizontal flow in vegetative (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.
