Elmendorf Tearing Strength Tester - QualiELM™ 6400
Elmendorf Tearing Strength Testers are essential tools used to measure the force required to propagate a tear in materials like textiles, paper, and plastic films. By simulating the tearing action, these testers help determine the material’s resistance to tearing, which is a critical factor in ensuring durability and quality. The instrument operates by applying a pendulum force to the material sample, where the energy absorbed during tearing provides an accurate measure of the material's tear resistance. These testers are widely used in quality control and R&D laboratories to assess the toughness and tear strength of fabrics, packaging materials, and paper products.
In the textile and paper industries, Elmendorf Tearing Strength Testers adhere to various international standards to ensure consistent testing results. Common standards include ASTM D1424 for woven and non-woven textiles, and TAPPI T414 for paper. These standards provide guidelines on sample preparation, testing procedures, and data interpretation, ensuring the results are reliable and comparable across different labs and industries. By complying with these standards, manufacturers can ensure their products meet necessary strength and durability criteria, enhancing overall performance and consumer satisfaction.
QualiELM™ 6400 can be classified by different test strengths; it can test the tear strength of paper, fiber, and PVC material. Grip the specimen and use a cutter to make a notch. The falling pendulum will use its swing force to tear the specimen, and the change in elevation energy of the pendulum will indicate the specimen’s tear strength. Meanwhile, the scale will display the tearing force. The tearing force is adjustable according to the specimen’s strength.
