ASTM D202

Test Materials: ASTM D202 specifies the use of various plastic films, paper, and surface materials to evaluate the coefficient of friction. A standardized frictional surface with defined roughness is essential for consistent measurements.
Test Process: The test involves placing the specimen on a horizontal plane and applying a controlled weight to measure the frictional force as the specimen slides across the surface. Conditions like temperature and humidity must be controlled to ensure valid results.
Test Result Interpretation: Results are calculated by determining the ratio of the frictional force to the weight of the specimen, yielding the coefficient of friction. A higher value indicates greater slip resistance, vital for applications in packaging and product design.
