1.1These test methods cover procedures for testing electrical insulating sleeving comprising a flexible tubular product made from a woven textile fibre base, such as cotton, rayon, nylon, or glass, thereafter impregnated, or coated, or impregnated and coated, with a suitable dielectric material.
1.2The procedures appear in the following sections:
Procedures | Section(s) |
Selection of Test Material | 5 |
Conditioning | 6 |
Dimensions | 7 to 11 |
Dielectric Breakdown Voltage | 12 to 17 |
Brittleness Temperature | 18 to 21 |
Flammability (See Test Methods D8355) | 22 to 23 |
Dielectric Breakdown Voltage After Short-Time Aging | 24 to 28 |
Oil Resistance | 29 to 32 |
Thermal Endurance | 33 to 39 |
Compatibility of Sleeving with Magnet Wire Insulation | 40 to 54 |
Solvent Resistance | 55 to 60 |
Hydrolytic Stability | 61 to 67 |
Effect of Push-Back After Heat Aging | 68 to 73 |
1.3The values stated in inch-pound units, except for °C, are to be regarded as the standard. The values in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4This is a fire-test-response standard. See Test Methods D8355, which contains procedures for flammability tests.
1.5This 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. For specific hazard statements, see 40.2 and 58.1.1.
Note 1:This standard resembles IEC 60684-2, Specification for Flexible Insulating Sleeving—Part 2 Methods of Test, in a number of ways, but is not consistently similar throughout. The data obtained using either standard are not necessarily technically equivalent.
1.6This 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.
