ASTM D350 : 21

Standard Test Methods for Flexible Treated Sleeving Used for Electrical Insulation

Standard Details

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

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

1.3 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 Test Methods D8355, which contains procedures for flammability tests.

1.5 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, 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.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International StandardDetails, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
