Methods of testing plastics. Other properties. Determination of coefficients of friction of plastics film

This specification outlines a standardized procedure for determining the coefficient of friction of plastic films. It serves as a specific methodological framework within a broader series dedicated to testing methods for plastic materials. The approach detailed in this document is designed to assess the surface interaction characteristics when two plastic films come into contact under controlled conditions. By adhering to the defined experimental setup and calculation parameters, manufacturers and quality control laboratories can obtain consistent and comparable data regarding the slip and grip properties of various film products. This facilitates better performance evaluation during processing and end-use applications where surface friction is a critical factor. The procedure ensures that measurements are taken using specific test equipment and environmental controls to minimize variability. Such data supports decision-making in product development and helps ensure that material suppliers meet the requirements set by various industry sectors. The method focuses specifically on the mechanical interaction between film surfaces without altering the material properties during the test process.
