The maximum media density measured in this procedure approaches the density at the theoretical saturation point. (astm.org)
5.4 The value of this test method to the green roof designer is that it provides an objective measure of maximum probable media density (under drained conditions) for estimating structural loads. (astm.org)
1.3 The maximum media density and associated moisture content measured in this procedure applies to drained conditions near the saturation point. (astm.org)
