2-Station Seatbelt Webbing Abrasion Tester，belt friction tester，belt friction tester

The 2-Station Seatbelt Webbing Abrasion Tester is designed to evaluate the abrasion resistance of seatbelt webbing materials used in lap belts, shoulder straps, and similar safety restraint systems. It simulates the wear and tear that occurs during long-term use, ensuring that seatbelt materials maintain their performance and durability.

Application

This benchtop-style tester allows operators to assess the decrease in webbing strength after repeated abrasion cycles. During the test, the webbing specimen is scraped against a coarse material for a specified number of cycles—typically 2.500 or more—and then examined for visible damage and tensile strength reduction.

The tester is ideal for automotive manufacturers, component suppliers, and research laboratories for quality control, product certification, and safety verification of webbing materials.

Standards

The tester complies with major international and automotive standards for seatbelt and webbing testing, including:

FMVSS 209 — Federal Motor Vehicle Safety Standard for Seatbelt Assemblies

ASTM D6770 — Standard Test Method for Abrasion Resistance of Textile Webbing

FED STD 191 — Federal Standard Test Methods for Textile Fabrics

MIL-232223B / MIL-T8363B — Military Standard for Webbing Materials

SAE J339 — Automotive Seatbelt Performance Standard

S5 1(d) — Durability Test Requirement

Designed specifically to meet FMVSS 209 requirements, this tester addresses the three core criteria of strength, performance, and durability for seatbelt components.

Features

Dual-Station Design for Higher Efficiency – Enables simultaneous testing of two specimens, improving productivity.

Automatic Cycle Control – User-defined test cycles with automatic stop function for accurate, repeatable results.

Precision Engineering – Durable mechanical components and low-friction bearings ensure long-term reliability.

Multi-Standard Compatibility – Supports ASTM, FMVSS, SAE, and MIL standards for versatile use.

Visual and Quantitative Evaluation – Allows both visual inspection and strength measurement after testing.

Compact Benchtop Configuration – Space-saving, easy to operate, ideal for laboratory environments.

Test Procedures

Install the seat belt fabric sample in the fixture and ensure it is securely fixed.

Adjust the friction device so that it contacts the fabric properly.

Set the desired cycle count and start the automated test program.

The test stops automatically when the cycle count is reached.

Inspect the sample visually and perform strength tests to evaluate abrasion performance.

Compare pre- and post-test results to assess material durability.

Maintenance Information

Keep friction surfaces clean and free from debris.

Inspect fixtures and moving parts for wear regularly.

Calibrate electronic counter periodically to ensure accuracy.

Ensure safe operation and avoid contact with moving components during testing.

Store the tester in a dry, dust-free environment to prolong lifespan.
