Tearing strength tester is a free-falling pendulum structure designed to perform an Elmendorf type tearing test. It helps evaluate the ballistic tearing strength of textiles, plastics, paper or board by applying sudden load to a half section of the material and ripping the sample apart. With the application of distinct weights, users can evaluate the exact amount of force required to tear the sample and which further defines its tearing strength.

Real-World Applications and Importance
The Tearing Strength Tester is pivotal in quality assurance, product development, and research across diverse industries. Its application extends from evaluating the tear resistance of fabric bags used in packaging to ensuring the structural integrity of aerospace and automotive components. The ability to accurately measure tearing strength aids in selecting the right materials for specific applications, enhancing product safety, performance, and customer satisfaction.
Material like textile or paper are highly sensitive to external pull or push forces. While in the production line, they tend to experience sharing forces like - being stretched, pulled, pressed, dropped, pulled or under vertical load. To survive all of that the material’s tearing strength must be as per industry standards. The tearing strength of material decides the amount of force it can take until it tears and fail in performance. It is very important that before taking the raw textile or paper material in use to deliver the end product, they are tested thoroughly for their strength capacity. In absence of a quality evaluation beforehand, the material may lead to the production of low-strength products hampering client user experience along with pulling the brand reputation down.
Tearing strength tester is a high-end quality testing equipment used to evaluate the resistance strength of textile, plastic or paper material against free-falling pendulum. The test sample is clamped using sample holding fixtures. One can tighten the sample as per their test requirement. Once the sample is fixed the pendulum can be loaded with a defined weight required for the test and the pendulum is pulled at a fixed height and held with at a point. The pendulum is raised to the maximum possible height to gain the maximum potential energy. Then the pendulum is released on the specimen free falling on the sample tearing it apart. The same procedure can be repeated with distinct weight to calculate the point at which it fails to perform. While conducting the test, the force applied on the specimen must be applied in the direction perpendicular to the plane of the specimen. The force applied to the specimen is computed with the help of readings on the scale provided with the instrument. The force can also be calculated with the relation to the pendulum capacity.

A Tearing Strength Tester, specifically the Elmendorf model offered by Pacorr, is a precision instrument used to determine the tearing strength of various materials such as textiles, paper, plastics, and cardboard. It operates based on a free-falling pendulum mechanism to apply a sudden force to the material, measuring the resistance to tearing.
Tearing strength is crucial for assessing the durability and performance of materials under stress or strain. It indicates how well a material can withstand external forces without failing, which is essential for ensuring the quality and longevity of the final product. High tearing strength is particularly important in industries such as textiles, packaging, aerospace, and automotive, where materials are often subjected to harsh conditions.
The Tearing Strength Tester works by clamping a sample of the material to be tested into the device. A pendulum is then loaded with a defined weight, pulled to a certain height, and released, allowing it to fall freely and tear through the sample. The energy lost by the pendulum, which correlates with the force required to tear the material, is measured to determine the material's tearing strength.
Yes, the Tearing Strength Tester by Pacorr is designed for a wide range of materials, including textiles, plastics, paper, and cardboard. It is versatile enough to accommodate different thicknesses and strengths by adjusting the pendulum weights, making it suitable for various industry applications.
Pacorr's Tearing Strength Tester is designed to provide highly accurate and repeatable test results. It achieves accuracy and repeatability of up to +/- 2% within its entire testing range. This precision is ensured through features like inbuilt calibration weights and a robust, corrosion-resistant structure for consistent performance.
