Standard Practice for Resistance of Adhesive Bonds to Chemical Reagents

Fecha:
2017-11-08 /Active
Significance and Use:

5.1 This practice is designed to determine the general effects of chemical reagents on the strength of the bonded system. It cannot distinguish between adsorption in the bulk adhesive or penetration at the adhesive/substrate interface.

Scope:

1.1 This practice provides a uniform procedure for the exposure of adhesively bonded substrates to selected environments. This practice also provides for a qualitative measure of the adhesive bond strength using existing standard methods after exposure.

1.2 The values stated in SI units are to be regarded as the standard. The values 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warnings, see Section 8.

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.
