Principle and Standards


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 reduced energy caused by tearing to attain the required force for tearing.


SLY-S1 Elmendorf Tearing Tester complies with various international and national standards:
ISO 6383-1-1983, ISO 1974, ISO 6383-2-1983, ASTM D1922, ASTM D689, ASTM D1424, TAPPI T414, GB/T 455,GB/T16578.2-2009
