Cardboard Stiffness Tester GT-N40 Product Introduction Application: Cardboard stiffness is the test of cardboard bending strength, the use of TABER (TABER) type stiffness tester. Suitable for determining the stiffness of paper and cardboard of low weight and thickness less than 1mm, the cardboard stiffness tester is the international standard common Taber (Taber) type stiffness tester. The instrument is suitable for paper and cardboard bending strength indicators, is the determination of cardboard stiffness of the special instrument. Standards: ISO 5628, ISO 2493-2, GB2679.3, QB/T 1051, GB/T 22364, TAPPI T489 Principle Designed according to the principle of equilibrium of the moment against the center of the rotating axis. The moment required for a piece of specimen, which is clamped vertically to the free end of the specimen, to be bent at an angle of 15° under the set conditions is the degree of the specimen, in units of MN, M. Feature The instrument adopts bilateral measurement and calculates the average value for more accurate data. Equipped with precision bearings to reduce friction. Mechanical structure, economical and practical.
