New Test Method for Standard Test Method for Determining the Drainage Rate of a Rainscreen Assembly using a Spacer Material
1. Scope
1. Scope
1.1 This test method determines the drainage rate of materials used to create a space when subjected to a water spray rate in accordance with Test Method E 331.
1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for
information only.
1.3 This standard may involve hazardous materials, operations, and equipment. 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 determine the applicability of regulatory limitations before use.

Rationale
When ASTM E2925 was balloted and approve as a material specification, there were two test methods embedded in the standard (Annex A and Annex B). It was agreed during the voting process to split the test methods off and make them stand alone standards. This proposed new test method is to address this commitment and deals with Annex B of ASTM E2925. Once this test method is approved, a proposal will be made to E2925 to reference this test method rather than Annex B.
