<p>Method of measuring tear resistance of paper. At present, the measurements are effected by using a multi-layer pack of paper and by tearing it by means of the potential energy of a pendulum. According to the invention, a paper sample (1) is provided with a tongue-shaped test blank (2), whose one end (3) is secured to the paper sample, said paper sample is torn by pulling the test blank and/or paper sample in different directions relative to each other and the tearing force is measured. </p> |
