Adhesives.org Standard Test Method to Measuring the Post Dispensing Volumetric Expansion of Aerosol Foam Sealants ASTM C1643 -08

This test method measures the volumetric expansion of aerosol foam sealants after dispensing. This test method provides a means for estimating the quantity of initial material required to dispense in order to fill a cavity. Aerosol foam sealants are used for a variety of applications intended to reduce airflow through the building envelope. This test method applies to two types of single component aerosol foam sealants: polyurethane and latex.
