Standard Test Method for Extrudability of Oil- and Resin-Base Caulking Compounds
SIGNIFICANCE AND USE
4.1 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.

7. Sampling
7.1 The compound to be tested shall be taken from a previously unopened container and thoroughly mixed before using.
8. Conditioning
8.1 After thoroughly cleaning the press-flow rheometer with solvent, condition the compound and the rheometer in the
laboratory for at least 5 h at 23 6 2°C (73.4 6 3.6°F).standard conditions.
9. Procedure
9.1 Remove the orifice holder from the rheometer cylinder and hold the open end up, making sure that the follower plate
remains inside.
9.2 Fill the cylinder with compound, avoiding air pockets. Strike off the filled cylinder with a spatula and replace the bottom
orifice cap. Connect the tube to an air supply and fix it to a support stand above the balance.
9.3 Adjust the air pressure to 207 kPa (30 psi) and open the air valve. If the pressure drops, readjust to 207 kPa while extrusion
is in progress. Close the air valve and discard this extruded compound. The apparatus is now ready for testing.
