What is Elmendorf Tear Test Machine ?

Tearing Strength Tester is the tensile force required to rupture a pre-slitsample under controlled test conditions.
This tearing strength tester is designed for tearing resistance of textile, non-woven fabrics, paper, paper board, thin film, ventilation tape, metal sheet materials and etc.

Elmendorf tear astm d1922 machine works on the principle of measuring the Internal tearing resistance, which isthe force perpendicular to the plane of the fabric required to propagate a single-rip or tear of a definedlength from a cut in the fabric when a sudden force is applied.The force required to continue a slitpreviously cut in a fabric is determined by measuring the work done in tearing the fabric through a fixeddistance.

Tear Testing Feature
1.Advanced calculation methods make sure precision test & good repetition.
2.Microcomputer system, can do auto test, calculate, analysis result, print test report.
3.Elmendorf tearing strength tester upload the test data.
4.Humanity operation system, Chinese and English operation interface with easy & convenience methods.
5.Elmendorf Tearing Tester Can look up all the datum & statistical result in mainframe freely.
6.Fabric tearing strength tester test unit can convention between N, gf, cN and ibs, suitable for differents standards requirements automatically.
7.Pneumatic sample grips and pendulum bob released to make sure equal clamping force.
8.Elmendorf Tearing Tester Cut sample automatically, making sure same shape of notch, reducing operation strength.
