GBD-S Tear Tester

Function and usage
Mainly test the tear property of paper , mainly using for tearing strength of not more than 1000mN quantitative paper, plastic and foil.

Standards

ISO 6383,ISO 1974,GB 11999,GB/T 455.1,GB/T 455.2,ASTM D1922,ASTM D1424,ASTM D689,TAPPI T414

Test principle

Lift the pendulum up to certain height, enable it to have a certain potential energy, pendulum tears the specimen while swinging down, computer calculates the decreasing energy caused by tearing.

Unit construction principle

Tearing tester elmendorf method is made up with pendulum bracket, pendulum, shaft, stationary clamp, movable clamp, augmenting weights, knife, pendulum releasing system, and computer.
