(Test Method)Standard Test Method for Evaluating the Tensile-Adhesion Performance of an Exterior Insulation and Finish System (EIFS)
Standard Test Method for Evaluating the Tensile-Adhesion Performance of an Exterior Insulation and Finish System (EIFS)
SCOPE
1.1 This test method evaluates the tensile-adhesion performance of an exterior insulation and finish System (EIFS) or its individual components by two different procedures: Procedure A, Dry Conditioning and Testing of Specimens; and Procedure B, Wet Conditioning and Testing of Specimens.
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 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 prior to use.
