Description / Abstract:

These test methods cover procedures for testing hookup wire.

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.

The test procedures and their locations are as follows:


Axial Stability (Longitudinal Change) After Thermal Exposure                   21

Bondability of Insulation to Potting Compounds                                      19

Capacitance                                                                                      9 to 12

Cold Bend Test                                                                                    26

Concentricity                                                                                       16

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                                                                              7

Tensile Properties                                                                               17

Vertical Flame Test                                                                             18

Voltage Rating of Hook-Up Wire A2 Voltage Withstand Test                     8

Wet Arc-Tracking                                                                                28
