ASTM E2485/E2485M-13(2018)

Standard Test Method for Freeze/Thaw Resistance of Exterior Insulation and Finish Systems (EIFS) and Water Resistive Barrier Coatings

SIGNIFICANCE AND USE
5.1 Resistance to freezing and thawing is a factor when determining the durability of EIFS, an EIFS with water-resistive barrier coatings, and water-resistive barrier coatings by itself.
SCOPE
1.1 This test method covers procedures for determining the effect of freezing and thawing of exterior insulation and finish systems (EIFS), an EIFS with water-resistive barrier coatings, and water-resistive barrier coatings by itself.  
1.2 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.  
1.3 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 to 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.
