Elmendorf Tearing Tester Falling-Pendulum Type is applied to the determination of tear resistance of textile, and also can be used for paper, plastic sheets, film, electrical tape, sheet metal etc.

The importance of Elmendorf Tearing Test

The tear strength is the resistance of fabric against tearing. The tear strength is vital for the textiles, bulletproof jackets, worker jeans, tents, apparel, sacks, and industrial applications. lf the tear strength is high, means punctures in the fabrics do not propagate easily. 

ASTM D 1424 elmendorf tear test principle 

The Tearing Strength Tester works on the principle of measuring the Internal tearing resistance, which isthe force perpendicular to the plane of the fabric required to propagate a single-rip or tear of a definedlength from a cut in the fabric when a sudden force is applied.The force required to continue a slitpreviously cut in a fabric is determined by measuring the work done in tearing the fabric through a fixeddistance.
