Two proposed standards concerning properties of aerosol foam
sealants are currently under development by ASTM International
committee C24 on building seals and sealants.
Both proposed standards, WK6156, Practice for Specimen Preparation
for Determining Rate of Air Leakage for Aerosol Foam Sealant Insulating
Materials and Other Joint Insulating Materials, and WK6328, Test
Method for Determining the Post Expansion for Aerosol Foam Sealants,
are under the jurisdiction of subcommittee C24.61 on aerosol foam
According to an ASTM news release, the purpose of standard WK6156
is to create a simplified means of measuring air permeance for
aerosol foam sealants used in building construction to reduce
energy-wasting air leakage in and out of the building envelope.
WK6328 is intended to provide uniform product label information
to the consumer concerning the amount of post-cure expansion of
an aerosol foam sealant to expect after initial dispensing. Subcommittee
C24.61 is actively seeking participation from any parties interested
in the development of either standard.
