ASTM C603-14
(Test Method)Standard Test Method for Extrusion Rate and Application Life of Elastomeric Sealants
Standard Test Method for Extrusion Rate and Application Life of Elastomeric Sealants
SIGNIFICANCE AND USE
4.1 The results obtained by this test method are simply a measure of the time required to extrude a known volume of sealant through a known orifice under a predetermined pressure.
4.2 This test method is not considered a measure of cure rate.
SCOPE
1.1 This test method covers two laboratory procedures for determining the extrusion rate and application life (or “pot life”) of elastomeric chemically curing sealants for use in building construction.
Note 1: These sealants are supplied with various rheological properties ranging from pourable liquids to nonsagging pastes. Single-component sealants are supplied ready for use upon opening the container, and their rate of cure is determined by the climatic conditions to which they are exposed. Multicomponent sealants are supplied as a base component and a curing agent separately packaged. After mixing the two parts, the sealant is ready for application, and curing begins immediately.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
1.3 There is no known ISO equivalent to this test method.
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.
