Product Description

Tearing Strength Tester is a consistent tool useful to determine the tearing strength of fabrics, plastic films, and similar materials. Tearing Strength Tester is the tensile force required to rupture a pre-slit sample under controlled test conditions.

The Tearing Strength Tester works on the principle of measuring the Internal tearing resistance, which is the force perpendicular to the plane of the fabric required to propagate a single-rip or tear of a defined length from a cut in the fabric when a sudden force is applied. The force required to continue a slit previously cut in a fabric is determined by measuring the work done in tearing the fabric through a fixed distance.

The apparatus consists of a pendulum carrying a clamp which is in alignment with a fixed clamp. The pendulum is in raised, starting position with maximum potential energy. The tear force is computed from scale reading and pendulum capacity.

Tearing Strength Tester is used to determine the average force in grams per sample required to propagate tearing through a specified length of textile or non – rigid cloth. Two sample are cited, a rectangular type and one with a constant radius testing length. The tester is equipped with a pendulum that applies the force. The test involves measuring the loss in the potential energy of the pendulum equating to the work done in tearing the test specimen

The tearing strength of the fabrics is essential to measure for best strength delivery. The testing strength tester of Presto has helped me a lot in ensuring the best quality and strength of fabrics delivered to my customers.

The strength of suture is very important for the success of a surgery. Being a manufacturer of suture I need to test the tensile strength of my products and ensure their best strength. The suture tensile strength tester has helped me in testing the products with great precision and accuracy.
