标准范围

规定了使用K？hler Molin、Lhomargy、MIT和Schopper测试仪测定纸张耐折性的方法。这些方法的原理是以一种标准化的方式前后折叠一张受到纵向应力的窄带纸，直到它断裂。K？hler-Molin、Lhomargy和Schopper方法适用于厚度不超过0.25 mm且抗拉强度大于1.33 kN/m的纸张。MIT测试仪具有可互换的折叠头，允许厚度不超过1.25 mm。

Specifies the methods for the determination of folding endurance of paper using K？hler-Molin, Lhomargy, MIT and Schopper testers. The principle of the methods is folding backwards and forwards in a standardized manner of a narrow strip of paper subjected to a longitudinal stress, until it breaks. The K？hler-Molin, Lhomargy and Schopper methods are applicable to paper of thicknesses up to 0,25 mm thick and having a tensile strength greater than 1,33 kN/m. The MIT tester has interchangeable folding heads allowing a range of thicknesses up to 1,25 mm.
