ASTM C1183-04(2008)
(Test Method)Standard Test Method for Extrusion Rate of Elastomeric Sealants
Standard Test Method for Extrusion Rate of Elastomeric Sealants
SIGNIFICANCE AND USE
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. Multicomponent sealants are supplied as a base component(s) and a curing agent separately packaged. After mixing the two or more parts, the sealant is ready for application. This test method is intended to provide a means to measure the extrusion rate spanning the range of rheological properties.
This test method also covers the option of measuring the freeze-thaw and heat stability of such sealants.
This test method provides for an option of either a metal or plastic nozzle. It is intended that the metal nozzle be used when greater precision is required, such as in ASTM specifications. The plastic nozzle may be used for general screening of sealant properties or for developmental purposes when a large number of test specimens are being tested.
This test method measures the volume of sealant extruded in 1 min at a given pressure (kPa or psi).
SCOPE
1.1 This test method covers two laboratory procedures for determining the extrusion rate of elastomeric sealants for use in building construction.
1.2 The values states in metric units are to be regarded as the standard. The values in parentheses are for information only.
1.3 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.
1.4 There is no known ISO equivalent to this test method.
