Information on the most widely used ASTM standards within the materials testing industry
Model: UT2089A, ASTM D1922
Elmendorf Tearing Tester is designed for the tearing test of films, sheets, flexible PVC, PVDC, waterproof films, woven materials, polypropylene, polyester, paper, cardboard, textiles and nonwovens.
What is Elmendorf Tear testing?
Elmendorf Tear testing determines the force required to continue the tearing of an initial cut in sheet materials such as paper, plastic film, textile and non-woven.

Key Features
2.1. Automatic release of pendulum, high test efficiency
2.2. Sudden power-off data saving function, after power-on, the data before power-off can be retained and the test can be continued.
2.3. Cooperate with microcomputer software to communicate (separately purchased) ARM processor, integrated control board design, reduce the failure rate.
2.4. 7-inch color touch screen, Chinese and English operation, easy to understand and easy to operate.
Lift the pendulum up to a certain height to give it an initial potential energy. The pendulum tears the specimen while swinging down. Computer calculates the decreased energy caused by tearing to obtain the required force for tearing.
