【国外标准】 Standard Test Method for Bond and Cohesion of One-Part Elastomeric Solvent Release-Type Sealants

This test method details the standard procedures for the determination of the bond and cohesion of one-part elastomeric solvent release-type sealants after high- and low-temperature aging. The materials and apparatuses needed for this test procedure are an extension machine, a forced-draft type oven, a convection type oven, a freezer chest or cold box, mortar blocks, glass plates, aluminum alloy plates, and polyethylene spacer bars. This test method also requires the use of the following reagents: acetone or methyl ethyl ketone solvents; detergent solution; and distilled water.1.1 This test method determines the bond and cohesion of one-part, elastomeric, solvent release-type sealants after high- and low-temperature aging.1.2 The subcommittee with jurisdiction is not aware of any similar ISO standard.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.NOTE 1: Currently there is no ISO standard similar to this test method.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.
