The proposed standard test method will ensure that building sealants provide durability and air tightness.

Sep 23, 2025

ASTM International’s building seals and sealants committee (C24) is developing a proposed standard that will help provide details to users and manufacturers on how sealant products perform as installed.

According to ASTM member Melissa Grant, the proposed standard (WK96116) will simulate the installation of aerosol foam sealants in conjunction with air barrier materials used in construction. Testing described in the proposed standard would help to ensure that air tightness is maintained during the designated life of construction. 

“This proposed test method would provide assurance to users that sealants are durable and can be used to provide air tightness,” says Grant.

Grant notes that the proposed standard will be used by manufacturers to demonstrate, through testing compliance, that their products are durable and recommended for installation. Laboratories will be able to test products as installed and provide feedback that can lead to educated decisions for ensuring an airtight, durable air sealant barrier. Finally, the proposed standard will provide assurance to consumers that products tested to the standard will be durable.   

“The proposed standard will help to ensure sealant is installed correctly and lasts to provide long term energy savings,” says Grant.
