ASTM D470-99
Historical Standard: ASTM D470-99 Standard Test Methods for Crosslinked Insulations and Jackets for Wire and Cable
SUPERSEDED (see Active link, below)
ASTM D470
1. Scope
1.1 These test methods cover procedures for testing crosslinked insulations and jackets for wire and cable. To determine the test to be made on the particular insulation or jacket, reference should be made to the product specification for that type. These test methods do not apply to the class of products known as flexible cords.
1.2 This standard does not purport to address all of the safety problems, 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 hazards see Section 4.
1.3. In this standard the temperature appearing first is the commonly used temperature.
1.4 The values stated in inch-pound units are standard. The values given in parentheses are provided for informational purposes only. See 1.3 for temperatures.
1.5 The procedures appear in the following sections:
Sections AC and DC Voltage Withstand Tests 23 to 30 Capacitance and Dissipation Factor Tests 83 to 88 Cold Bend 107 Cold Bend, Long-Time Voltage Test on Short Specimens 41 to 44 Double AC Voltage Test on Short Specimens 39 to 40 Electrical Tests of Insulation 18 to 22 Heat Distortion Test 106 Horizontal Flame Test 89 to 93 Insulation Resistance Tests on Completed Cable 31 to 38 Mineral Filler Content, Determination of 99 to 101 Ozone Resistance Test 71 to 82 Partial-Discharge Test 45 to 51 Physical Tests of Insulation and Jacket Compounds 5 to 17 Surface Resistivity Test 102 to 104 Track Resistance Test 109 to 111 U-Bend Discharge Test 102 to 104 Water Absorption Test 52 to 57 Water Absorption Tests, Accelerated 58 to 60 Water Absorption Test on Fibrous Coverings 94 to 98
