1、Designation: C910 16Standard Test Method forBond and Cohesion of One-Part Elastomeric SolventRelease-Type Sealants1This standard is issued under the fixed designation C910; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year o
2、f last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () 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 high-
3、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 and
4、 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.

Prepare the six mortar blocks asdescribed in 4.5.7.2 Precondition the unopened containers of sealant atstandard conditions for a minimum of 24 h.7.3 Prepare three test specimens for each substrate to

17、specimens by allowing them to set for24 h at standard conditions, then drying them in a convectionoven for 7 days at 50 6 1C (122 6 2F).7.5 Place the specimens in freezer for 24 h at 23 6 3C(10 6 5F). Dislodge spacer bars from sealant, but do notremove spacer bars from assembled specimens.7.6 Remove
18、 specimens from the freezer and condition themfor1hatstandard conditions.7.7 Place the specimens in a forced-draft oven for 7 days at70 6 2C (158 6 3.6F).7.8 Remove the specimens from the oven. Place them in afreezer for 24 h at 23 6 3C (10 6 5F).7.9 Place the specimens, while frozen, in the grips o
