(Test Method)Standard Test Method for Extrudability of Oil- and Resin-Base Caulking Compounds
Standard Test Method for Extrudability of Oil- and Resin-Base Caulking Compounds
SIGNIFICANCE AND USE
The rate of extrusion determined by this test may be correlated with the rate of gunning of the compound.
SCOPE
1.1 This test method describes the laboratory procedure for determining the rate of extrusion of oil- and resin-base caulking compounds.
1.2 The values stated in metric (SI) units are to be regarded as the standard. The values given in parentheses are provided 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.
