This document specifies a method for determining the resistance to tearing of plastic films and sheets. It is applicable to plastics materials in the form of films and sheets, regardless of their thickness. The method described is based on the trouser tear test, which involves the formation of a notch in the specimen and the measurement of the force required to propagate the tear. The test is performed using a tensile testing machine equipped with appropriate grips and a tearing device. The procedure includes the preparation of test specimens, the calibration of equipment, and the determination of the tearing resistance. This method is suitable for use with a wide range of plastics materials and can be applied to both rigid and flexible films and sheets. The results obtained are used to compare the tearing resistance of different materials or to assess the effect of processing conditions on the properties of the material.
