ASTM D470-2013標(biāo)準(zhǔn)介紹
ASTM D470-13是關(guān)于《電線和電纜用交聯(lián)絕緣材料與套管的標(biāo)準(zhǔn)試驗方法 》現(xiàn)行版本標(biāo)準(zhǔn)修訂于2013年，替代原ASTM D470-99版本使用。
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, refer to the product specification for that type. These test methods do not apply to the class of products known as flexible cords.
1.2 In many instances the insulation or jacket cannot be tested unless it has been formed around a conductor or cable. Therefore, tests are done on insulated or jacketed wire or cable in these test methods solely to determine the relevant property of the insulation or jacket and not to test the conductor or completed cable.
1.3 The procedures appear in the following sections:
Sections
AC and DC Voltage Withstand Tests22 to 29
Capacitance and Dissipation Factor Tests38 to 44
Cold Bend128
Cold Bend, Long-Time Voltage Test on Short Specimens51 to 57

Partial-Discharge Test58 to 64
Physical Tests of Insulation and Jacket Compounds 5 to 16
Surface Resistivity Test116 to 120
Track Resistance Test129 to 132
U-Bend Discharge Test121 to 125
Water Absorption Test65 to 71
Water Absorption Test, Accelerated72 to 86
Water Absorption Test on Fibrous Coverings 105 to 110
1.4 Whenever two sets of values are presented, in different units, the values in the first set are the standard, while those in the parentheses are for information only.
1.5 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.
