Elmendorf Tearing Tester - TNG1022

The TNG1022 Elmendorf Tearing Tester is designed to determine tear strength according to ASTM D1424 and ISO 13937-1. The instrument operates by lifting one end of a pendulum to a defined height, allowing it to swing and tear a sample clamped between jaws. The energy required to tear the sample is calculated using the formula P = FS, based on the law of conservation of energy. The tester is suitable for materials such as woven fabrics, paper, plastic cloth, film, electrical tape, and sheet metal. It is not recommended for sparse fabrics or stretch materials, as tear direction may change during testing. The device features an LCD screen for displaying results and includes a microprocessor for automatic data analysis. The physical dimensions of the TNG1022 are 520 mm in length, 300 mm in width, and 530 mm in height.

The Elmendorf Tearing Strength Tester is used for the determination of the tear strength of various woven fabrics (Elmendorf method), and can also be used to determine the tear strength of paper, plastic cloth, film, electrical tape, sheet metal, and other materials. While, the Elmendorf tester does not apply to sparse fabric or stretch materials, as the tear direction may shift during testing.

An instrument for the LCD screen display, intuitive and simple operation.

Microprocessor, with automatic data detection and analysis functions, calculation, and display of experimental results.

High testing accuracy, and reliable performance.

The powerful function can determine the tearing strength of various woven fabrics, and also can determine the tearing strength of thick paper, plastic cloth, electrical tape, etc.

Test Principle of the Elmendorf Test

Lift one end of the pendulum to a certain height, so that it has a certain potential energy; when the clamp clamps the sample, release the pendulum, and the pendulum that is around the axis of natural gravity falls, with its own energy to tear the sample, according to the law of conservation of energy to measure the energy consumed by the tear, by P = FS formula to calculate the force required to tear the sample.
