ASTM D1894

Standard Test Method for Static and Kinetic Coefficients of Friction of Plastic Film and Sheeting

ASTM D1894 Test Materials

ASTM D1894 specifies using thin plastic films or sheeting, typically cut to 250 mm x 130 mm for the base and approximately 120 mm x 120 mm for the sled, with a maximum thickness of 0.254 mm.

ASTM D1894 Test Process

The test uses a coefficient of friction tester, where a sled covered with film is pulled across a film-coated surface at a constant speed. Forces are measured to calculate static (force to start motion) and kinetic (force during motion) coefficients​.

ASTM D1894 Test Result Interpretation

The coefficients of friction are derived as the ratio of the pulling force to the sled’s weight, providing insights into the material’s surface interactions and suitability for applications​.
