A tear is generally uneven and, and usually unplanned. An exception is a tear along a perforated line, such as those found on a roll of toilet paper or paper towels, which has been previously partially cut, so the effort of tearing will most likely produce a straight line.
The speed at which a tear resistance test is conducted can affect the test significantly. Tear transmission resistance is common for acceptance testing with materials such as paper and rubber. Tear resistance in textiles involves the load required to spread a single "rip-tongue" type of tear or the type of tear where the material is initially cut.
Materials vary in their vulnerability to tearing. Some materials may be quite resistant to tearing when they are in their full form, but when a small cut or tear is made, the material becomes compromised, and the effort needed to continue tearing along that line becomes less.
Tearing Resistance Tester tests the tear force required to tear samples of paper, film, board and other sheet materials. The equipment is designed to directly read the gF(Tear Force) per one piece. The Tearing Resistance Test instrument scale is calibrated to indicate the average force exerted when a certain number of piles are torn together.
The Digital Elmendorf Tearing Tester is using Elmendorf method to determine the tear force of textile fabrics which requires to propagate a single-rip tear of defined length from a cut in a fabric when a sudden force is applied. Test range is 200-32000CN, while the impact force is corresponding to the specific pendulum. They determine ballistic tearing strength by propagating a single-rip tongue-type tear starting from a cut in a sample. The design is much user-friendly with wide range to meet different test and standards.
