The Automotive Wire Scratch Resistance Tester is designed to evaluate the abrasion resistance and durability of automotive wire insulation under mechanical wear conditions. You can use this device to simulate long-term friction, vibration, and contact stress, ensuring that wire coatings maintain integrity and prevent conductor exposure during service life.

Application

This tester is suitable for:

(1) Abrasion resistance testing of automotive wires and cables.

(2) Evaluation of insulation durability in wire harness systems.

(3) Quality control of cable coatings and insulation materials.

(4) R&D validation of wiring systems for automotive, aerospace, and electronics applications.

Standards

The tester adheres to global standards for material abrasion testing, including:

ISO 6722-1(Road vehicles – Electrical cables – Test methods for abrasion resistance)

SAE J2394(Standard test for electrical resistance of automotive wire insulation under abrasion)

LV 112(Volkswagen standard for automotive cable durability)

GB/T 5023(China’s national standard for electric cables – Abrasion tests)

UL 758(Appliance Wiring Material standard for insulation integrity)

These standards ensure consistent evaluation of wire insulation durability, coating adhesion, and resistance to mechanical wear.

Working Principle

The tester operates bycontrolled mechanical abrasion:

Sample Mounting: Automotive wires or cables are clamped between two moving jaws.

Abrasion Cycle: A weighted abrasive head (e.g., tungsten carbide) moves back and forth across the wire surface at a preset load (e.g., 20 N) and speed (e.g., 30 cycles/min).

Cycle Execution: The test runs until insulation breach or a predefined cycle count (e.g., 10.000 cycles) is reached.

Performance Assessment: Post-test, samples are evaluated for insulation damage, conductor exposure, or coating wear using microscopy or electrical continuity tests.

Test Principle & Applications

Abrasion Resistance Testing (ISO 6722-1/SAE J2394):

Wires are subjected to 5.000–20.000 cycles to simulate years of vibration and friction.

Pass/fail criteria: No conductor exposure or insulation breach (e.g.,
