Description

Significance and Use

Preformed tape sealants are tacky, deformable solids that are used under compression between two substrates in a variety of sealing applications. This procedure measures the softness of a preformed tape sealant and gives an indication of the preformed tape sealant’s ease of compression during installation. The resistance to penetration may also give an indication of the toughness of the preformed tape sealant.

1. Scope

1.1 This test method describes a laboratory procedure for determining the softness of preformed tape sealants.

Note 1—Cone penetration methods applicable to greases and to petrolatum are described in Test Methods D 217 and D 937. Test Method D 2451 also uses a penetration technique for determining the degree of set in sash glazing compounds.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parenthesis are for information only.

1.3 The subcommittee with jurisdiction is not aware of any similar ISO standard.

1.4 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
