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