Standard Test Methods for Nonmetallic Semi-Conducting and Electrically Insulating Rubber Tapes


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:

Referenced Documents2
Dielectric Strength33-40
Dissipation Factor22-26
Heat Exposure46-49
Ozone Resistance41-45
Sample Requirements4
Tensile Strength17-21
Volume Resistivity27-34
Ultraviolet and Weather Resistance50-54

1.3 The SI values are the standard. The inch-pound values given in parentheses are for information purposes only.

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.

Significance and Use

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.
