As per ASTM D - 1894 to determine the coefficients of friction of plastic films and sheeting.
Additionally in Computerized model Digital Controller would change with Micro-controller with RS 232 communication andInterface software would be offered to be installed in user PC. Through this Load Vs travel graph along with result storage & Printout is possible. Also there would be provision to merge 10 samples at a time with single printout showing mean value & Standard deviation.
As per Tappy T - 815 standard to determine the coefficients of friction between film to film, film to metal and film to glass.
