The ISO 15359-1999 standard specifies a test method for the determination of the static and dynamic coefficients of friction of paper and Cardboard by the horizontal method. The standard describes in detail the test conditions and procedures required during the measurement process, including how to accurately measure the friction performance of paper at a specified degree of abrasion. The test involves sliding the paper on a horizontal surface and measurement of the horizontal force required to initiate and maintain the sliding. The static coefficient of friction represents the friction force at the beginning of the sliding, while the dynamic coefficient of friction represents the friction force at the continuous sliding. This standard applies to various paper and Cardboard types to help evaluate the friction characteristics of paper in practical applications. The standard appendix provides the recommended symbols and test conditions to ensure the accuracy and conformity of the test results.
