ASTM D2202-00 (R2019) PDF Download

The ASTM D2202-00 (R2019) standard provides a laboratory procedure for determining the degree of slump of a sealant when used in a vertical joint in a structure. The degree of slump refers to the amount of deformation or sagging that occurs in the sealant when it is applied vertically.

Excessive sealant slump or sag in a vertical joint can lead to problems such as improper bead shape or inadequate sealant thickness in the completed joint. Therefore, this test method aims to evaluate this specific application characteristic but does not predict the performance capability of the sealant after installation.

The standard presents the option to use either inch-pound or SI (metric) units for measurement, and both sets of values are provided. It is important to note that the standard does not specify the performance criteria for the sealant based on the slump measurement. Thus, the user should compare this test method to the related ISO standard (ISO 7390) to understand any differences between the two.
