    Significance and Use

    5.1 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 D217 and D937. Test Method D2451 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 standard. Temperature values are also provided (in parentheses) in degrees Fahrenheit.

    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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
