Coefficient of friction testing measures the ease with which two surfaces in contact are able to slide past one another. There are two different values associated with the coefficient of friction – static and kinetic. Static friction must be overcome in order to initialize motion between the two surfaces, and kinetic friction is the resistance to sliding once the surfaces are in relative motion.
Because substrate cleanliness is so important to gathering reliable data, appropriate measures must be taken to ensure freedom from dirt, grease, and other contaminants. |
Shown below are the standards that are applicable to Coefficient of frictionCoefficient of Friction Testing:
| ASTM D1894 |
Static and Kinetic Coefficients of Friction of Plastic Film and Sheeting is the most common standard DDL tests to involving coefficient of friction.
