ASTM D896-97

Standard Test Method for Resistance of Adhesive Bonds to Chemical Reagents

SCOPE
1.1 This test method provides a uniform procedure for the exposure of adhesively bonded substrates to selected environments. This test method also provides for a qualitative measure of the adhesive bond strength using existing standard methods after exposure.
1.2 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. For specific precautions, see Section 8.
1.3 Values stated in SI units are to be regarded as the standard.
