This tester is used to measure the tear force of woven fabrics and non-woven fabric with special regulations in tearing direction.It also can be applied to determine the paper marking industry etc.
Standards: GB/T3917.1,GB3919.1,FZ/T75001,ASTM D1424,ISO13937.1,ISO4674.2 etc.
Basically used for testing the force value of (Elmendorf) drop hammer is the specialized appliance to test whether the value of the tearing tester is accurate.
The principle is to put the weight on the testing clamp, then turn on the tester, with the sector plate swing, the weight rise. Test the highest height; calculate the increased potential energy, compare the standard tearing length with the value on the indicator, calculate the error.
The weight is configurable for any needed force value, so it is easy to use. It is also precision, easy operation, easy to carry.
Suitable instrument: drop-hammer type and electronic drop hammer tearing tester for fabric, paper making and plastic industry.
