Tearing Strength Tester is the tensile force required to rupture a pre-slit sample under controlled test conditions. PRESTO Tearing Strength Tester is designed as per standards ASTM D1424-09(2013), ASTM D624-00(2012), ASTM D1776, ASTM D689. • High Quality rugged structure with corrosion resistant main body
Tearing strength testing is a vital aspect of assessing the quality and durability of fabrics. It aids manufacturers, designers and consumers in order to comprehend how well a material can withstand tearing focuses. Of course, this is needed to identify the suitability of various applications. There are various methods employed for tearing . Fig: Elmendorf Tear Strength Tester. Formula of tear strength test: Mean tearing strength (gf) = K × mean value of scale reading / n. Where, n = number of test specimens tested together. k = 16 without any augmenting weight for 1600 gf range. k = 32 with any augmenting weight for 3200 gf range. k = 64 with both augmenting weight for 6400 gf range.

Tear Tester which was designed by Dr. Thwing and Mr. Armin Elmendorf. This method, developed over a century ago established the industry standards used worldwide today to measure tear strength. The ProTear Testers provide a rapid and precise way to evaluate the tear resistance of sheet materials including This test method uses a computer-based constant-rate-of-extension-type (CRE) tensile testing machine to test the tearing strength of fabrics using the tongue tear process. An Introduction to ASTM D2261 . A common name for ASTM D2261 is the “Tongue Tear Test.” It also has the name of Trapezoid Tear Test.
Originally introduced in 1964, ASTM D2261 was most recently updated in 2013 and specifies the method for tear testing of fabrics by the tongue (single rip) procedure to measure the tearing strength of the fabric. This test method applies to most textile fabrics, including those that are treated and untreated, woven, knitted, or unwoven.Performance, and Testing TAPPI PRESS Nonwovens: Theory, Process, Performance, and Testing Edited by Albin F. Turbak Prepared for the Nonwovens Division . Trapezoid tearing strength of geotextiles Triboelectric effect Two-dimensional webs Two-phase headbox Ultrasonic vibrations Uniaxial tension and bending Uniform Abrasion
Tear strength is the tensile force required to rupture a pre-slit woven fabric sample under controlled conditions. Edge tearing strength of paper is the load required to tear a sample over a V-notch fixture. Typical graph showing a tear . The Elmendorf Tear Strength Tester is an instrument specially used to test the tear strength (strength) of fabrics. It uses the impact pendulum method to measure tear strength, also known as the pendulum or falling .
This falling pendulum-type testing instrument will easily help you in the easy determination of tearing strength. You can perform hassle-free testing operations single-handed with the help of this tearing strength tester. It has inbuilt calibration weights and a strong gripping fixture for holding the test samples accurately. Here we have .An easy-to-use, modern paper strength testing instrument delivering accurate and repeatable results.
