ASTM D7532-09(2021)

5.1?Selection of or development of a carpet adhesive, for direct glue or adhered applications requires knowledge of the adhesive's ability to perform adequately when it is found necessary to correct an installation concern, such as bubbles or wrinkles, by re-rolling or application of dead weight to the affected area without the application or injection of additional adhesive.

5.2?Adhesive bonding of some carpet backings to substrates and the adhesive bonding of carpet backings to a pad foundation, double stick or glue application, require that prior to bonding the adhesive is to be dried sufficiently to allow for no transfer of adhesive as a result of slight finger pressure.

1.1?This practice will provide a protocol for determining the effect of extended drying (open time) periods on the shear and peel strength performance of a carpet adhesive when bonding a carpet backing or standard duck cloth material to a substrate.

1.2?The values stated in SI units are to be regarded as the standard. The values given 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4?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.
