Digital Fabric Elmendorf Tear Tester, A computer controlled falling-pendulum instrument, to determine the ballistic tearing strength of textiles, plastics, paper or board.
It enables rapid determination of the dynamic resistance of materials designed to be subjected to strong shearing loads (e.g. fabrics) or liable to be damaged by sharp or heavy objects (e.g. paper bags). Subsequently, the test was naturally adopted for all materials in the form of sheet or films, cardboards, cloth, knitted fabrics, plastic films, aluminum foil, non-woven fabrics, complex flexible packaging etc. But does not apply to sparse fabric or stretch materials which tearing direction might be shift in test.

For testing film, paper, advise use XHV-01C tearing strength tester

BS 4253, ASTM D1424/5734 , DIN 53862, BS EN ISO 13937, ISO1974/9290.

Works in accordance with all known test standards.

Touch screen operation, RS-232 data output, equipped Tearing Test software

Auto specimen notching

Repeatable, pneumatic specimen gripping system guarantees sufficient clamping pressure to avoid all slipping phenomena, thus ensuring perfect the experimental conditions.

Automatic compensation for friction and leveling errors, no slave pointer, therefore no friction, alignment and maintenance problems.

Unit: N, CN, Lb, g, kg can be selected.
