JIS-P8125, TAPPI-T489, ISO-2493

This tester is used to evaluate the stiffness of paper, plastic film, and textile according to the Clark’s method. The operator is to clip the test specimen between the 2 rolls and rotate it left and right until the test specimen falls over 90°. When the test specimen falls over 90° the operator is to measure the brattish length to calculate the stiffness.
