4.1 Excessive sealant slump or sag in a vertical joint may cause improper bead shape or inadequate sealant thickness in the completed joint. Slump measurements, as described in this test method, serve to evaluate only this application characteristic; they do not predict the performance capability of the sealant after installation.

1.1 This test method covers a laboratory procedure for the determination of the degree of slump of a sealant when used in a vertical joint in a structure.

1.2 The values stated in either inch-pound or SI (metric) units are to be separately regarded as the standard. Within the text, the inch-pound units are shown in parentheses.

1.3 This 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.

Note 1: A related ISO standard is ISO 7390. The user should compare to determine how it differs from this test method.
