Coefficient of friction (COF) is the maximum value of the frictional force divided by the normal force. Coefficient of friction (COF) testing is used for a variety of materials from lubricants, to films to household items (ceramic tiles) to determine the frictional characteristics of a material.

There are two primary types of CoF tests: static and kinetic. The static CoF test measures the force required to initiate movement (overcoming static friction), while the kinetic CoF test measures the force needed to maintain motion (overcoming kinetic friction).

COF tester and test fixture: The test to determine the coefficient of friction according to ISO 8295 can be easily performed on a static zwickiLine testing machine with an additional ZwickRoell test fixture.

Feb 13, 2024 · Coefficient of friction (CoF) testing is a means of quantifying the resistance to sliding between two surfaces. This testing is commonly carried out in a multitude of industries including textiles, coatings, flooring, and automotive.

Jun 20, 2024 · The Coefficient of Friction (COF) test outcomes have many practical applications across different sectors. In manufacturing industry, these results help to select materials that offer suitable friction levels thus guaranteeing product safety and functionality.

Coefficient of friction (COF) testing is widely valued for its important role in the processes of production, transportation and marketing. Coefficient of Friction tester conforms to the multiple national and international standards: ASTM D1894 - Standard Test Method for Static and Kinetic Coefficients of Friction of Plastic Film and Sheeting

COF is defined as the force required to move one surface over another, divided by the total force applied normal to those surfaces. The values are between zero and one and are dimensionless. There are two common basic COF testers — sliding plane and incline plane.

With CoF testing, a coefficient of friction tester measures both static and kinetic friction, showing how a material will perform in different conditions. A low CoF indicates a smoother, low-resistance interaction, while a higher CoF suggests more grip between surfaces.

The coefficient of friction (COF) test measures static and kinetic friction. FUTEK LSB206 load cell can accurately measure friction forces maintaining a nonlinearity of ±0.1%. When performing coefficient of friction testing to ASTM D1894 standard it is essential to use a high precision force sensor and high sampling rate instrument.

The coefficient of friction, or COF, is determined by the ease with which two surfaces slide against each other. The dimensionless value of the coefficient of friction is the ratio of the force required to slide the surfaces to the force perpendicular to the surfaces.
