Tearing Strength Tester

Presto Stantest Private Limited offers Tearing Strength Tester. This method covers the determination of the average force in grams per specimen required to propagate tearing through a specified length of plastic film or no rigid Sheeting. Two specimen are cited, a rectangular type and one with a constant radius testing length. The company also offers Salt Spray Chamber, Scratch Hardness Tester, Erichsen Cupping Test Machine, Bursting Strength Tester, Ozone Chamber, etc.
Significance: This method is of value in ranking relative tearing resistance of various plastic films and thin sheeting of comparable thickness. Experience has shown the test to have its best reliability on relatively less extensible films and sheeting. Variable elongation and oblique tearing effects on the more extensible films preclude its use as a precise production control tool for these types of plastic.
Standards: D-689 ;BS 4153; ASTM D1424; DIN 53862; M&S 29.
