Elmendorf Tearing Tester

Overview

Elmendorf tearing tester is designed to measure average tearing force of materials from the energy loss of a falling pendulum. By well simulating the practical case, a test specimen is exposed to a sudden heavy load which causes the test specimen to tear, propagating an existing cut, such as a seam or a button hole. Start from a single tongue-type cut in sample and measure tearing strength from the energy loss of a falling pendulum while the cut propagating, the testing result is considered usable only when in 20 - 80 % of each full scale range, or else next weight should replace. It is designed to determine tearing force of fabric, non-woven, paper, cardboard, plastic film, etc. Providing solid results for QC, material R&D, Certification & Testing.

Standards

BS EN ISO 13937   BS EN ISO 4674-2  BS EN ISO 21974  ASTM D1424  ASTM D5734  ASTM D689-96a  TAPPI T414 om-12  NEXT 17  DIN EN 21974  DIN EN ISO 1974  DIN EN ISO 6383-2  ISO 9290  M&S P29  NEXT 17  GB/T 3917.1  GB/T 455

Feature

• Automatic calibration, automatic checking weight and automatic balance the empty pendulum.
• Optical encoder measuring system detect swing angle of pendulum can reduce friction and increase accuracy.
• Lower energy consumption design.
• Wide measuring range reaches 128N.
• USB data export makes analysis and data storage more convenient.
