Elmendorf Tearing Strength Tester - lab instrument
I. Product Overview
TheManual Tear Strength Testeris a precision instrument designed to measure the tear resistance of materials using standardized methods such as the Elmendorf or tongue tear test. It evaluates the force required to propagate a tear in textiles, plastics, rubber, and composites, ensuring compliance with international quality standards.
Type:Mechanical pendulum tear tester
Test Standards:ASTM D1424 (Elmendorf), ISO 34 (Tongue method)
Tear Modes:
Elmendorf:Single-edge tear propagation
Tongue:Central slit expansion
Capacity:50–5000 mN (adjustable via pendulum weights)
Sample Size:63×127mm (Elmendorf) / 50×200mm (Tongue)
II. Technical Specifications
