Folding endurance of paper and board

This test is used to determine the folding endurance of paper or board using the Köhler-Molin, Lhomargy, MIT, and Schopper testers. During the test, a narrow strip of paper is folded forwards and backward in a standardized manner, so that it is subjected to longitudinal stress until it breaks.
