ASTM C736-12 (R2017) PDF Download

The ASTM C736-12 (R2017) standard outlines a laboratory procedure for evaluating the extension-recovery and adhesion properties of latex sealants. The purpose of this test method is to determine how well a latex sealant performs when subjected to limited amounts of extension. It provides guidelines for assessing the ability of the sealant to stretch and recover without losing its adhesion properties.

The values stated in this standard are in SI (metric) units and should be considered as the standard. Any values given in parentheses are provided for informational purposes only. It is also noted that there is an ISO standard, ISO 7389, that is related to this test method. Users are encouraged to compare the ASTM standard with the ISO standard to understand any differences between the two.
