Digital film coefficient of friction tester which easy to operate to test material friction coefficient.
Introduction
As digital film coefficient of friction tester manufacturer, we know that the coefficient of friction is very important in all industries.
Coefficient of friction means, the friction between the surfaces of objects is proportional to the positive pressure. It is one of the fundamental properties of materials and is related to the roughness of the paper and film surface and not to the size of the contact area. The coefficient of friction can be classified into dynamic and static coefficients by which the frictional properties of a material can be assessed.
In various industries, the coefficient of friction is an important index for evaluating the slippery performance of materials, especially in high-speed production lines, by testing the coefficient of friction, it can ensure that the materials can be transported, processed and packaged smoothly, and meet the needs of efficient production. Therefore, testing and controlling the coefficient of friction of materials is very necessary.
Common test standards are ASTM D1894, for digital film coefficient of friction tester measurement.
Test Purpose
The purpose of the coefficient of friction test is to evaluate the friction properties between materials, as well as the slip properties of materials.

Test Procedure
Digital Film Coefficient of Friction Tester COF Tester
1) Prepare the test sample: First, cut the digital film coefficient of friction tester into the desired size and shape for testing. Make sure the sample is clean and free of any contaminants. This can be achieved by using clean cutting tools and cleaning agents. Ensure that you avoid touching the surface of the sample when cutting and handling it to prevent contamination.
2)Place the test sample on the instrument: Secure the digital film coefficient of friction tester sample to the test surface of the instrument. This can be achieved by using a fixing method such as clamps or tape. In addition, ensure that another specimen is in contact with the felt side of the slide and secure it with. This will ensure the accuracy and consistency of the test.
3)Perform the test: Start the test on the instrument. During the test, the two specimens are moved relative to each other and the instrument measures the friction between the test specimens. The instrument calculates and displays the static and dynamic friction coefficients. Test parameters can be set according to the test requirements, such as movement speed, pressure, etc. Ensure the accuracy and stability of the testing process.
4)Repeat testing: Repeat testing is performed on multiple samples to ensure consistency and accuracy of results. This can be achieved by using the same test conditions and methods. Ensure that the instrument and samples are in the same condition prior to each test. Multiple tests may be performed as needed.
