ASTM D6325-98(2019)
(Test Method)Standard Test Method for Determining Open Assembly Time of Carpet Mastic Adhesives
Standard Test Method for Determining Open Assembly Time of Carpet Mastic Adhesives
SIGNIFICANCE AND USE
4.1 The ability to have a sufficient open assembly time is critical when bonding a carpet. An adhesive with too short an open assembly time will not allow the installer enough time to position the carpet before the adhesive is dried beyond use. A product with too long an open assembly time will not provide enough dry time for the carpet to bond to the intended substrate without movement of the carpet.
4.2 The test method provides a means of measuring the open assembly time for an adhesive. Use of such a test method can aid both the manufacturer to develop and the user to select the appropriate adhesive for the installation of carpet.
4.3 Test Method C679 was used as a model for this test method.
SCOPE
1.1 This test method describes a procedure to measure open assembly time for a troweled carpet adhesive.
1.2 This test method provides an evaluation of the ability of an adhesive to effectively wet out the intended carpet backing.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
