Applications:

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.

Product Information:

The universal wear testing machine features a fully automatic testing mode with automatic counting, automatic stop upon test completion, and a buzzer alert function.  The clamp-type sample fixing method allows for quick sample replacement, improving testing efficiency.  Its compact design makes it easy to move and offers flexibility to meet various practical application requirements.

Test Procedures

1. Preparation Phase

Equipment and Accessory Inspection

Ensure the instrument's power connection is secure, and all components (fixtures, abrasives, weights, diaphragms, etc.) are intact and clean, free from oil stains or debris.

Prepare test samples (cut to standard dimensions) and prepare tools such as sample mounting wrenches.

2. Sample and Abrasive Installation

Sample Mounting

Use the sample mounting wrench to open the fixture, place the diaphragm and sample into the fixture, and tighten the fixture knob to secure the sample.

Abrasive and Weight Installation

Fix the abrasive to the upper fixture, and then install the corresponding weight (select according to the test load requirements).

3. Parameter Settings

Power On and Interface Access

Turn on the instrument's power switch and access the operation display screen interface.

Setting Test Parameters

Set the number of test cycles (such as the number of friction cycles required by the standard);

Adjust the air pressure value (the sample will expand to a preset height with the air pressure, adapting to flat grinding/curved grinding and other test modes).

4. Starting the Test

Adjusting the Contact Position

Lower the upper fixture to ensure close contact between the abrasive and the sample surface.

Starting the Test

Press the "Start" button, and the instrument enters the automatic friction mode (the abrasive and the sample continuously rub against each other).

The test status can be monitored through the display screen during the test.

5. Test Completion and Subsequent Operations

Automatic Shutdown

When the sample is worn through or the set number of cycles is reached, the instrument automatically stops and beeps.

Sample Processing and Analysis

Turn off the instrument's power, remove the sample, check the degree of wear, and record the data (such as wear area, weight change, etc.).

Cleaning and Maintenance

Clean up any remaining debris inside the instrument and keep the equipment clean for future use.

FAQ

1.What is the Universal Wear Tester (UWT) used for?

The UWT is used to evaluate the wear resistance and friction performance of textiles, coatings, and other materials under controlled conditions, simulating real-world usage.

2.Which materials can be tested with this machine?

It can test fabrics, leather, coated textiles, plastic films, and other materials that require abrasion or friction resistance assessment.

3.How does the UWT operate?

The tester applies a controlled load while moving the specimen against a standard abrasive surface or counter material, measuring wear and friction over a set number of cycles.

4.Can the testing parameters be adjusted?

Yes, the UWT allows adjustment of load, speed, stroke length, and number of cycles to meet different testing standards and research requirements.

5.What standards does the UWT comply with?

It is designed to meet international standards such as ASTM D4966. ISO 12947. and related textile and material wear testing guidelines.
