(Test Method)Standard Test Method for Shrinkage and Tenacity of Oil- and Resin-Base Caulking Compounds
Standard Test Method for Shrinkage and Tenacity of Oil- and Resin-Base Caulking Compounds
SIGNIFICANCE AND USE
5.1 Shrinkage is a measure of the nonvolatile solids of an oil- or resin-base compound. A compound that exhibits excessive shrinkage may have a tendency to crack or shink from the sides of a joint when in service.
5.2 Tenacity is the measure of the flexibility of an oil- or resin-base caulking compound. Oil- or resin-base caulking compounds that cure excessively hard and do not remain flexible may fail prematurely because of the inability to absorb movement.
SCOPE
1.1 This test method describes a laboratory procedure for determining the shrinkage of oil- and resin-base (Note) caulking compounds, as well as the evaluation of the tenacity property of such compounds. This test method is applicable to both gun (Type I) and knife (Type II) grades.
Note 1: This is not a suitable test method for water-base products.
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 The subcommittee with jurisdiction is not aware of any similar ISO standard.
1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
