SLY S1 Elmendorf Tearing Tester

SLY-S1 is based on Elmendorf method to measure tearing strength of plastic films, textile, woven and non-woven materials. Labthink tear tester is a user-friend instrument and test range is from 200gf to 6400gf with suitable pendulum.


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.


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