【国外标准】 Standard Test Methods for Hookup Wire Insulation

AbstractThese test methods detail the standard procedures for testing hookup wire insulations including all components of the insulation system used on single insulated conductors or an assembly of single insulated conductors such as a cable bundle and harness or flat ribbon cable. The insulating materials include not only the primary insulation over the conductor, but also insulating jackets over shielded constructions. The test procedures covered here shall be performed in the conditions or shall determine the properties, as follows: axial stability (longitudinal change) after thermal exposure; bondability to potting compounds; capacitance; cold bend test; concentricity; crush resistance; dielectric breakdown voltage; dimensions; dry-arc tracking; dynamic cut-through; fluid immersion; high temperature shock; insulation-continuity proof tests; insulation resistance; partial discharge (corona) inception and extinction voltage; relative thermal life and temperature index; strip force; surface resistance; tensile properties; vertical flame test; voltage rating of hook-up wire; voltage withstand test; and wet arc-tracking.1.1 These test methods cover procedures for testing hookup wire.1.2 For the purposes of these test methods, hookup wire insulation includes all components of the insulation system used on single insulated conductors or an assembly of single insulated conductors such as a cable bundle and harness or flat ribbon cable. The insulating materials include not only the primary insulation over the conductor, but also insulating jackets over shielded constructions.1.3 These test methods and their locations are as follows:  SectionAxial Stability (Longitudinal Change) After Thermal Exposure 20Bondability of Insulation to Potting Compounds 18Capacitance 9 to 11Cold Bend Test 25Concentricity 25Crush Resistance 19Dielectric Breakdown Voltage 5Dimensions 14Dry-arc Tracking 28Dynamic Cut-through 21Fluid Immersion 22High Temperature Shock 23Insulation-Continuity Proof Tests 12Insulation Resistance 6Partial Discharge (Corona) Inception and Extinction Voltage 24Relative Thermal Life and Temperature Index 13Strip Force 26Surface Resistance 26Tensile Properties 16Vertical Flame 17Vertical Flame Test A 18.5(Test Method D8354)Vertical Flame Test B 17.6 – 17.11.4Voltage Rating of Hook-Up Wire Annex A1Voltage Withstand Test 8Wet Arc-tracking 271.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.1.5 This standard measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not, by itself, incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.1.6 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.1.7 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 warning statements, see 17.1.3, 24.4, and Note 18.1.8 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.
