Falling pendulum Paper Testing Equipments / Tear Strength Tester
Specifications
Tear Strength Tester
1 . Accurate , low-cost and high quality
2 . Suitable for fabrics and textile
3 . ASTM D 1424
The Usage
Tear Strength Tester are accurate , low-cost and high quality falling pendulum tear testing Instruments with analog display for the determination of the average force required to propagate a single-rip tongue-type tear starting from a cut in paper , cardboard , plastics , non-woven and woven fabrics , with proper configuration .
Tear Strength Tester meeting ASTM standards is suitable for most fabrics including woven , layered blankets , napped pile , blanket , and air bag fabrics , and provided the fabric does not tear in the direction crosswise to the direction of the force application during the test . The fabrics may be untreated , heavily sized , coated , resin-treated , or otherwise treated . This test method covers the measurement of the average force required to propagate a single-rip tear starting from a cut in a non-woven fabric using a falling-pendulum (Elmendorf) apparatus .
