Standard Test Methods for Multi-Modal Strength Testing of Autohesives (Contact Adhesives)
|Publication Date:||15 July 1992|
|ICS Code (Adhesives):||83.180|
These test methods cover procedures by which autohesives can be tested in four commonly practiced stressing modes, namely: compression shear, cleavage, climbing drum peel, and T-peel, and in various combinations of rigid-to-rigid, flexible-to-rigid, and flexible-to-flexible
The bond-formation process used with autohesives is unlike that of all other adhesives and in consequence, testing of autohesives requires methods that are unlike those provided by other ASTM standards. See Annex A1.
A choice of adherends is available in each test mode. The combination of adherends that can be bonded together is limited to those shown in Appendix X1.
Methods for application of pressure are available in each test mode. For a particular combination of substrates, the means available for application of pressure are limited to those shown in Appendix X2.
The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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. Specific precautionary statements are given in 7.5.
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
