Introduction
Product Introduction
The Scratch-Resistance Testing Machine is specifically designed to evaluate the wear resistance of low-voltage wires and cables used in road vehicles.
The instrument scratches the insulating surface of automotive wires under controlled conditions to determine their durability and resistance to abrasion.
This device ensures the safety and reliability of vehicle wiring by accurately identifying insulation vulnerabilities during mechanical stress tests.
Applicable Standards
JB/T 8139-1999 — Road Vehicle Wire Scratch-Resistance Test Method
JIS C3046 — Test Methods for Electrical Insulation of Cables
JASO D 611 — Japanese Automotive Standard for Wire Insulation Abrasion Resistance
Product Advantages
Provides accurate and repeatable evaluation of wire and cable insulation wear.
Automatically stops the test if the needle penetrates the insulation and contacts the conductor, ensuring safe operation.
Supports multiple test weights for adjustable force application.
Bidirectional scraping simulates realistic wear conditions on automotive wires.
Compact design with easy sample mounting for laboratory and quality control use.
Product Features
Bidirectional scraping device ensures uniform wear along the wire axis.

FAQ
1. What type of wires can be tested with this machine?
It is designed for low-voltage automotive wires and cables but can be adapted for other insulated wires requiring scratch-resistance testing.
2. How is the test conducted?
The scraping needle moves bidirectionally along the wire under specified weight, stroke, and frequency to simulate wear conditions.
3. What happens if the needle penetrates the insulation?
The machine automatically stops to prevent damage to the tester and ensure safety.
4. Can different test weights be applied?
Yes, the machine supports 500 g, 750 g, 1000 g, and 1250 g weights to simulate different abrasion forces.
5. How is the sample mounted?
The wire is firmly fixed on a steel anvil, with a minimum distance of 10 mm from the test points to the sample ends.
