TAPPI T815

Test Materials: TAPPI T815 specifies that the primary test materials include various types of paper and paperboard. The samples should be conditioned at a standard temperature and humidity to ensure consistent testing conditions. Additionally, a suitable testing surface, typically a polished metal or glass surface, is used to measure the coefficient of friction accurately.

Test Process: The test process involves placing a standardized weight on the test material and sliding it across the testing surface. The force required to initiate and maintain the sliding motion is measured, allowing for the calculation of static and kinetic coefficients of friction. Care must be taken to maintain consistent speed and environmental conditions during the test.

Test Result Interpretation: Results from TAPPI T815 are interpreted by comparing the measured coefficients of friction against industry standards. High coefficients indicate better slip resistance, while lower values suggest higher friction. These results inform packaging design and performance, ensuring materials meet the necessary requirements for their intended application.
