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

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
