ASTM C 1642 : 2014

1.1This practice is intended to determine the air leakage rate of aerosol foam sealants as measured in a standardized jig. This practice provides a procedure for preparing the test apparatus and further describes the application of aerosol foam sealant and other joint fillers to the apparatus prior to conducting Test Method E283.

1.2This practice allows testing laboratories to quantify the air leakage rate of aerosol foam sealants or joint filling products using Test Method E283 and reporting the data in L/(s · m²) according to Practice E29.

1.3This practice is used in conjunction with Test Method E283. Although Test Method E283 is a laboratory test method used with fenestration products, individuals interested in performing field air leakage tests on installed units should reference Test Method E783 and AAMA 502.

1.4Aerosol foam sealants are used for a variety of end use applications generally intended to reduce air leakage in the building envelope.

1.5Insulating type materials also will be found suitable for evaluation with this practice.

1.6There are no other known practices or test methods that specify the preparation of the assemblies used to determine the air leakage rate of gap filling sealants, dry preformed foams or insulations.

1.7The values given in SI units are the standard. The inch-pound units in parentheses are for information only.

1.8This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
