Elmendorf Tear tester, a computer controlled falling-pendulum instrument, to decide the ballistic tearing strength of textiles, plastics, paper or board. Tear Strength Tester complies with ASTM D1424/1922/5734, ISO 1974/9290/6383-2, BS ISO 13937, etc. The tearing tester is further enhanced and supported by the easy to use computer. Elmendorf Tear Strength Tester will show its good performance when you do Elmendorf tear test.

Product Elmendorf tear strength tester (patented product), is used to determine the ballistic tearing strength of textiles, plastics, paper or board.

Elmendorf tear tester (protear) enables rapid determination of the dynamic resistance of materials designed to be subject 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, aluminium foil, non-woven fabrics, complex flexible packaging etc.

Elmendorf type tear tester is not applied to sparse fabric or stretch materials which the tearing direction might be shift in test.

Compressed air of 0.4~ 0.7 mPa is required.


Works in accordance with all known test standards.
The model is the only one that covers the most completed test range from 0 to 12800cN.
RS-232 data output, equipped with Lenovo computer and Tearing Test software, and Panasonic printer.
Machine can be controlled by the large graphic touch panel without computer and software.
Automatic specimen clamping and notching.
Repeatable, pneumatic specimen gripping system guarantees sufficient clamping pressure to avoid all slipping phenomena, thus ensuring perfect reproducibility of the experimental conditions.
Automatic compensation for friction and leveling errors, no slave pointer, therefore no friction, alignment and maintenance problems.
