Tearing Resistance Tester

This method for the determination of the tearing resistance of paper consists of measuring the work done when a sample of paper is torn through a specified distance. The work is done partly in rupturing the paper along the line of the tear and partly in bending the paper as it is being torn. The total work done is used, along with the length of a single force which, for the purpose of this method is described as the force required continuing the tearing of a single sheet of paper. This force expressed in grams weight is defined as the tearing resistance of the paper.
