1、Designation: C 910 06Standard Test Method forBond and Cohesion of One-Part Elastomeric SolventRelease-Type Sealants1This standard is issued under the fixed designation C 910; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year
2、 of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method determines the bond and cohesion ofone-part, elastomeric, solvent release-type sealants after hi
3、gh-and low-temperature aging.1.2 The subcommittee with jurisdiction is not aware of anysimilar ISO standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety
4、and health practices and determine the applica-bility of regulatory limitations prior to use.NOTE 1Currently there is no ISO standard similar to this test method.2.
