Coefficient of Friction Tester

Model: UT2049E; ISO 8295, ASTM D1894

UT2049E Coefficient of Friction Tester is Based on the ISO 8295 standard. It is professionally suitable for measuring the static friction coefficient and dynamic friction coefficient when plastic film and sheet, rubber, paper, cardboard, woven bag, fabric style, metal material composite belt, conveyor belt, wood, coating, brake pad, wiper, shoe material, tire and other materials slide. By measuring the slip properties of the material, the quality and process indicators of the material production can be controlled and adjusted to meet the requirements of product use. In addition, it can also be used to measure the slip properties of cosmetics, eye drops and other daily chemical products. 


Standards: ISO 8295 | ASTM D1894: Coefficient of Friction Static and kinetic, or dynamic, coefficient of friction of plastic films, GB/T 10006. TAPPI T816.

Key Features

  • Features
  • How it works
  • Standard

1. The equipment is controlled by microcomputer, the test process is automated, with menu-type operation interface, PVC control panel and LCD screen, which is convenient for users to carry out test operation and data viewing.

2. The system accessories are all made of well-known manufacturer components, with stable and reliable performance, high-precision force sensor, and the highest test accuracy in China: 0.01N 

3. No mechanical knob, full digital system, digital correction and zeroing.

4. Specially designed drive system, smooth operation, more accurate test results.

5. The system can measure the static friction coefficient and dynamic friction coefficient of the sample at the same time.

6. Equipped with a micro printer to automatically print the test report of a single piece or a group of samples.

7. The instrument test table and test slider have undergone degaussing treatment and remanence detection, which effectively reduces the system test error.

8. Group data, embedded data statistical analysis function.

9. The interface design of the instrument is simple, the operation is simpler, and the use is convenient.


The two specimen surfaces are laid flat together, and under a certain contact pressure, the two surfaces are moved relative to each other, and the required force is recorded.

ISO 8295 Coefficient of Friction Testing Plastic Film Sheeting

ISO 8295 specifies a standardized laboratory method to determine the static (starting) coefficient of friction and the dynamic (sliding) coefficient of friction of plastic films and sheeting — most commonly when the film slides over itself (film/ film) or over another substance (film/ metal, film/ other plastic surface, etc.).

ASTM D1894 coefficient of friction plastic film

ASTM D1894 quantifies surface slip resistance of plastic films and thin sheets sliding against identical film, metal, glass or other flat substrates, generating empirical friction data for production quality control and material performance evaluation. Test static (starting) and kinetic (continuous sliding) friction coefficients of plastic film & thin sheeting; primary for flexible packaging materials.

ISO 21182 coefficient of friction for light conveyor belts

ISO 21182 specifies test procedures to measure static coefficient of friction (μs) and dynamic coefficient of friction (μD) for light conveyor belts. Quantify how "grippy" or "slippery" a belt cover surface is when sliding against a standardized steel panel under a defined normal load.
