(Test Method)Standard Test Methods for Nonmetallic Semi-Conducting and Electrically Insulating Rubber Tapes
Standard Test Methods for Nonmetallic Semi-Conducting and Electrically Insulating Rubber Tapes
SIGNIFICANCE AND USE
5.1 The physical and electrical properties, including break strength, elongation, dielectric strength, dissipation factor, permittivity, fusion, etc., will vary with temperature and moisture content. Control the temperature and moisture content of the sample for these test methods to yield consistent and reproducible results.
SCOPE
1.1 These test methods cover the methods and procedures for testing electrically insulating and semi-nonmetallic conducting rubber tapes designed for splicing, terminating, and sheath repair of electrical wire and cable.
1.2 The test methods appear in the following sections:

1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.Note 1—There is no IEC equivalent to these methods.
1.4 Unless otherwise stated, measurements are made on tapes from which the removable separator has been removed.
1.5 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. For specific precaution statements see 43.1.
1.6 This is a fire-test response standard.
