    1. 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:

    ProceduresSections
    Brittleness Temperature18 to 22
    Compatibility of Sleeving with Magnet Wire Insulation45 to 59
    Conditioning6
    Dielectric Breakdown Voltage12 to 17
    Dielectric Breakdown Voltage After Short-Time Aging29 to 33
    Dimensions7 to 11
    Effect of Push-Back After Heat Aging73 to 78
    Flammability22 to 28
    Hydrolytic Stability 66 to 72
    Oil Resistance34 to 37
    Selection of Test Material5
    Solvent Resistance 60 to 55
    Thermal Endurance38 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 provided for information only.

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

    1.5 These test methods can be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory conditions, but should not be used to describe or appraise the fire hazard or fire risk of materials, products, or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which take into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use.

    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 may not be technically equivalent.
