APPLICATION

This procedure is used for measuring the tear strength of the thermoplastic films or non-rigid sheet. By this test method, we determine the average force to propagate tearing through a specified length of plastic film or non-rigid sheeting. This test method is of value in ranking relative tearing resistance of various plastic film and this sheeting of comparable thickness.

USP

• It consists of stationary & movable clamp.
• Stopper for holding the pendulum in a raised position & releasing it instantaneously.
• Indicating device for taking the reading of pendulum swings when released.
• Template die or shear type cutter for cutting specimen.
