ASTM D1894 Coefficient of Friction Plastic Films

ASTM D1894 describes a standard test method for determination of the static and dynamic coefficients of friction (initial and sliding friction coefficients) of plastic film and sheeting when sliding them over themselves or other materials under specified test conditions.

The coefficients of friction provide information about the sliding properties of plastic films and play an important role in the packaging industry in particular and are relevant both in quality control during film production and in the development of film material for technical design. They also play an important role in EV battery testing in the form of separator film.

ASTM D1894 is not technically equivalent to its ISO counterpart ISO 8295, so the results of the two methods cannot be directly compared.
