2、or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method evaluates the tensile-adhesion perfor-mance of an exterior i
3、nsulation and finish System (EIFS) or itsindividual components by two different procedures: ProcedureA, Dry Conditioning and Testing of Specimens; and ProcedureB, Wet Conditioning and Testing of Specimens.1.2 The values stated in either SI units or inch-pound unitsare to be regarded separately as st

Combiningvalues from the two systems may result in non-conformancewith the standard.1.3 This standard does not purport to address all of thesafety concerns, if any, a

It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Significance and Use5.1 Maintenance of adequate tensile adhesion of EIFScomponents to each other, and
10、 to the substrate are essential forlong term performance of the system.5.2 The tensile-adhesion properties obtained by this testmethod are not purported to be representative of wind load orother structural and moisture related properties of the EIFSwall assembly.

Samples maybe cut from larger sheets for ease of system fabrication.NOTE 1As required above, test specimen size shall not be smaller than50 by 50 mm 2 by 2 in. However, as test specimen size increases, axialloading eccentricities becom

To limit the effect of eccentricities, maximum test samplesize should be limited to about 76 by 76 mm 3 by 3 in.7.2 Apply the adhesive in a uniform, continuous layer, suchthat the measured tensile load is representative of a fullybonded 5
