SIGNIFICANCE AND USE
5.1 This test method is a standard procedure for determining the drainage efficiency of an EIFS clad wall assembly.
SCOPE
1.1 This test method determines the drainage efficiency of EIFS clad wall assemblies when subjected to a water spray rate in accordance with Test Method E331.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
