ASTM D4325 – Standard Test Methods for Nonmetallic Semi-Conducting and Electrically Insulating Rubber Tapes
Description:
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-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:
| Section | |
| Referenced Documents | 2 |
| Conditioning | 5 – 6 |
| Dielectric Strength | 35 – 40 |
| Dimensions | 11 – 16 |
| Dissipation Factor | 22 – 26 |
| Elongation | 17 – 21 |
| Heat Exposure | 46 – 49 |
| Fusion | 7 – 10 |
| Ozone Resistance | 41 – 45 |
| Permittivity | 22 – 26 |
| Sample Requirements | 4 |
| Tensile Strength | 17 – 21 |
| Volume Resistivity | 27 – 34 |
| Ultraviolet and Weather Resistance | 50 – 54 |
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.
