Tearing Strength Tester
Tearing Strength Tester is a consistent tool useful to determine the tearing strength of fabrics, plastic films, and similar materials. Tearing Strength Tester is the tensile force required to rupture a pre-slit sample under controlled test conditions.
Tearing Strength Testers are high quality, low cost and accurate falling pendulum tear testing equipment having an analog display used to determine the average force required to propagate a single tear starting from a cut in plastics, paper,cardboard, woven fabrics and non-woven fabrics with proper configuration. The model also meets ASTM standards.
Tearing strength tester is a laboratory test equipment used to evaluate the average force in grams per sample essential to spread, tearing through a specified length of non-rigid sheets or plastic films. The tester works on the principle of determining the internal tearing resistance, the force perpendicular to the surface of the sheet needed to split multiple plies through a specified area after the rip has been started.
The instrument is also used in textile industry to measure the strength of fabrics or other similar materials. The strength of fabrics is calculated by measuring the work done in tearing through a fixed length of test specimens using Elmendorf Tear Tester.
Tearing strength tester is used to calculate the average force per sample in grams required to circulate tearing throughout an individual length of non-rigid sheeting or plastic film. Two samples can be placed one with a rectangular shape and another with constant radius testing length. The instrument is equipped with a constant radius testing length. The tester is duly fitted with a pendulum that exerts the force and determines a loss in the potential energy of the pendulum equating to work done, required to tear the paper.
