scope:
1.1 These test methods cover procedures for testing crosslinked insulations and jackets for wire and cable. To determine the test to be made on the particular insulation or jacket, refer to the product specification for that type. These test methods do not apply to the class of products known as flexible cords.
1.2 In many instances the insulation or jacket cannot be tested unless it has been formed around a conductor or cable. Therefore, tests are done on insulated or jacketed wire or cable in these test methods solely to determine the relevant property of the insulation or jacket and not to test the conductor or completed cable.
1.3 The procedures appear in the following sections:
| Sections | |
| AC and DC Voltage Withstand Tests | 22 to 29 |
| Capacitance and Dissipation Factor Tests | 38 to 44 |
| Cold Bend | 128 |
| Cold Bend, Long-Time Voltage Test on Short Specimens | 51 to 57 |
| Double AC Voltage Test on Short Specimens | 45 to 50 |
| Electrical Tests of Insulation | 17 to 64 |
| Heat Distortion Test | 127 |
| Horizontal Flame Test | 100 to 104 |
| Insulation Resistance Tests on Completed Cable | 30 to 37 |
| Mineral Filler Content, Determination of | 111 to 115 |
| Ozone Resistance Test | 87 to 99 |
| Partial-Discharge Test | 58 to 64 |
| Physical Tests of Insulation and Jacket Compounds | 5 to 16 |
| Surface Resistivity Test | 116 to 120 |
| Track Resistance Test | 129 to 132 |
| U-Bend Discharge Test | 121 to 125 |
| Water Absorption Test | 65 to 71 |
| Water Absorption Test, Accelerated | 72 to 86 |
| Water Absorption Test on Fibrous Coverings | 105 to 110 |
1.4 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in the parentheses are for information only.
1.5 This standard does not purport to address all of the safety problems, 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 hazards see Section 4.
