Standard Test Methods for Flexible Treated Sleeving Used for Electrical Insulation
|Publication Date:||10 September 2001|
|ICS Code (Plastics and rubber insulating materials):||29.035.20|
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:
|Brittleness Temperature||18 to 22|
|Compatibility of Sleeving with Magnet Wire Insulation||45 to 59|
|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 55|
|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 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.
