significance And Use:

12.1 The dielectric breakdown voltage of the sleeving is of importance as a measure of its ability to withstand electrical stress without failure. This value does not correspond to the dielectric... View More

scope:

1.1 These 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.

1.2 The procedures appear in the following sections:

Procedures	Sections

Brittleness Temperature	18 to 21
Compatibility of Sleeving with Magnet Wire Insulation	45 to 59
Conditioning	6
Dielectric Breakdown Voltage	12 to 17
Dielectric Breakdown Voltage After Short-Time Aging	29 to 33
Dimensions	7 to 11
Effect of Push-Back After Heat Aging	73 to 78
Flammability	22 to 28
Hydrolytic Stability	66 to 72
Oil Resistance	34 to 37
Selection of Test Material	5
Solvent Resistance	60 to 65
Thermal Endurance	38 to 44

1.3 The 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.

1.4 This is a fire-test-response standard. See Sections 22 through 28, which are the procedures for flammability tests.

1.5 This standard measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions.

1.6 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 hazard statements, see 45.2 and 63.1.1.

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.

1.7 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.
