ASTM - E2396/E2396M

Standard Test Method for Saturated Water Permeability of Granular Drainage Media [Falling-Head Method] for Vegetative (Green) Roof Systems

inactive
Organization: ASTM
Publication Date: 1 June 2015
Status: inactive
Page Count: 3
ICS Code (Roofs): 91.060.20
ICS Code (Plant growing): 65.020.20
scope:

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.

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

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.

The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

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.
