Sealants

The Liquid Sealant Validation Program was established to validate the published test results of the various sealant products on the market. The intent of the program is to provide specifiers and end-users of sealant products an unbiased method to judge whether sealant products will perform at the levels of the manufacturer's published data sheet for that particular product.

Performance Properties Profile

Validation of the SWR Institute Performance Properties Profile shall include the following ASTM tests:

►C 719 (Canada - Method 14.4 - Can 2-19.0-M77) Adhesion and Cohesion of Elastomeric Joint Sealants Under Cyclic Movement (Hockman Cycle). Test must be performed to validate the greatest joint movement capability claimed on the Manufacturer's data sheet.****As of September 2012, ASTM C 661 is no longer required under SWR Institute's Sealant Validation Program.

Please note: All ASTM tests performed shall be the latest or current edition. All tests performed shall NOT be modified in any way. Sealant color for testing shall be selected from manufacturer's standard color chart.

Validation shall remain in effect for five years from the date of the validation testing. In the event the sealant product is re-formulated by the manufacturer, the product must be re-tested and re-validated. Upon expiration of the validated product, it must be re-submitted for testing even if no changes have been made to the product.
