Application

Auto Elmendorf Tear Tester (patented product), is used 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, 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.

Features  

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, windows based TESTEX Tearing Test software.

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 levelling errors, no slave pointer, therefore no friction, alignment and maintenance problems.
