ASTM D 350:2021

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 Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
