Tear strength tester is an instrument used to test the tear strength of textile fabrics. The tear strength defined as the force required to start or continue a tear in a fabric under specified conditions. Determining the tear strength of fabric is very important.

Salient Features

• The equipment consist of a falling pendulums to cover various measuring ranges.
• Provided with cutting templates, cutting knife and board for preparing sample for the test.
• There are start and stop safety solenoids to hold the pendulum at the beginning and end of each test.
• The tear test parameters include tearing strength, peak load and median load.

The test method for determining tear strength involves imparting a cut in the center. There is an opposing tail, also called tongue, which is clamped in the instrument and pulled apart.

Applications
The tear strength tester is widely used in many areas. Some of the areas where it finds application are:

• Textile Industry
• Plastic Industry
• Paper Industry
