Universal Wear Tester(UWT)/Stoll Quartermaster

Application:

Universal Wear Tester (UWT) is used to determines the wear and abrasion resistance of fabric used in clothing, footwear and industrials. Supplied with surface abrasion head (inflated diaphragm method, flex abrasion head, depth abrasion test device, flat abrasion (frosting) and pilling test device as well as necessary weights and initial supply of abrasive. Fitted with built-in timer and mechanical cycle counter. 

Standard

• ASTM Standards: D3514, D3885, D3886 (textile, coating, and plastic wear resistance)
• AATCC Standards: 119, 120 (fabric abrasion and pilling resistance)
• FTMS Standards: 191/5300/5302 (federal textile durability protocols)
• FORD Standards: EFB 15J2, BN 112-01 (automotive interior material testing)
• JIS L1096-1999(A)
• CNS 12915-1991

Product Advantages:

• Multi-Functional Testing: Conducts flat, curved, edge, and fold abrasion tests, as well as frosting, pilling, and gigging resistance evaluations.
• Versatile Material Compatibility: Suitable for woven/knitted fabrics, coated textiles, plastics, leather, rubber, paper, and more.
• Consistent Performance: Built-in timer and mechanical cycle counter ensure repeatable results with 120 double strokes per minute (25mm stroke).
• Precision Engineering: Improved air injection system for uniform diaphragm inflation; superior clamping mechanism maintains sample tension.
• Customizable Testing: Optional accessories available for specialized applications (e.g., liquid immersion tests in water, oil, or solvents).
• Robust Construction: Durable design withstands heavy industrial use, while compact dimensions optimize lab space.

Product Features:

• Dual Abrasion Heads: Includes surface abrasion head (inflated diaphragm method) and flex abrasion head for diverse testing modes.
• Interchangeable Accessories: Compatible with weights, blades, and sample holders to simulate real-world wear scenarios.
• Advanced Control System: LCD interface with programmable cycles, stroke length, and speed settings; real-time progress display.
• Uniform Testing Conditions: Motor-driven 120 RPM speed and 25mm stroke length guarantee standardized results across operators.
• Enhanced Clamping Mechanism: Securely tensions samples to prevent slippage during high-speed reciprocation.
• Liquid Immersion Capability: Test samples under wet conditions (water, oil, solvents) to simulate extreme environments.

Work Principle of Universal Wear Tester：

This instrument mainly consists of a control system and a friction system. Mount the specimen on the fixture and tighten it. Put down the upper jig with sandpaper, adjust the position of the weight to make the sandpaper contact with the surface of the specimen, set the friction times of the specimen through the control system, and start the instrument. The base of the lower fixture moves back and forth, so that the specimen and sandpaper rub against each other, and the instrument stops when the number of movements reaches the set value, and the specimen is removed to observe its wear degree.
