Scope of standard 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: '' Section Axial Stability (Longitudinal Change) After Thermal Exposure 21 Bondability of Insulation to Potting Compounds 19 Capacitance 9 to 12 Cold Bend Test 26 Concentricity 26 Crush Resistance 20 Dielectric Breakdown Voltage 5 Dimensions 15 Dry-arc Tracking 29 Dynamic Cut-through 22 Fluid Immersion 23 High Temperature Shock 24 Insulation-Continuity Proof Tests 13 Insulation Resistance 6 Partial Discharge (Corona) Inception and Extinction Voltage 25 Relative Thermal Life and Temperature Index 14 Strip Force 27 Surface Resistance 27 Tensile Properties 17 Vertical Flame 18 Vertical Flame Test A 18.5 (Test Method D8354) Vertical Flame Test B 18.6 ''' 18.11.4 Voltage Rating of Hook-Up Wire Annex A1 Voltage Withstand Test 8 Wet Arc-tracking 28 1.4''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 12.2.1, 12.4.1.8, 18.1.3, 25.4, and Note 19. 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.
