Elmendorf Tear Tester for Paper and Cardboard Tear Strength Test

Elmendorf tearing tester is used to test the tear strength of paper and cardboard, and can also be used to test the tear resistance of laminate composites such as textiles, leather and film. Further more, the machine is also suitable for thin film, waterproof, coils, woven materials, paper, paperboard, textiles and non-woven fabrics and other tear resistance detection. The tear tester complies with ISO 6383, ISO 1974, GB 11999, GB/T 455.1, GB/T 455.2, ASTM D1922 and other standard test requirements.

Scope of Aapplication of Elmendorf Tear Tester: The machine used for the determination of the tear resistance of various woven fabrics (Elmendorf method), It is used to test the burst strength test of textiles, woven fabrics, non-woven fabrics, coated fabrics for impact tearing silk, cotton cloth, various papers, cardboards and single-layer and multi-layer corrugated cardboard.

Elmendorf Tearing Tester’s Test Principle: Lift the pendulum to a certain height, so that it has a certain potential energy. When the pendulum swings freely, it uses its own stored energy to tear the sample. The energy consumed by the tear sample is measured by the sensor, and the force required by the tear sample is obtained
