SCOPE. This method is intended to determine the force required to tear a material. The method is applicable to all types of polymeric material and in particular footwear soling materials or suitable material cut from finished soles or shoes.ISO 6383-1:2015 specifies a method of determining the tear resistance of plastic film or sheet less than 1 mm thick, in the form of standard trouser-shaped test specimens, tested under defined conditions of pre-treatment, temperature, humidity, and speed of testing.
5.1 This test method is of value in rating the tear-propagation resistance of various plastic films and thin sheeting of comparable thickness. For highly extensible film or sheeting the deformation energy of the specimen legs is significantly greater than the tearing energy. The tear-propagation resistance in slightly extensible or non-extensible film or sheeting is distinguished from the tear .
ASTM D2261, ASTM D882 and ISO 6383-1 Film and Sheeting—Determination of Tear Resistance Part 1 Trouser Tear Method. Why Use a Standard Test Method Like ASTM D1938? ASTM D1938 is useful for support of engineering design and development, to confirm internal quality assurance, to compare one material versus another, to provide a clear . The critical tearing energy (N/m) associated with the trouser test method (ASTM D1938 [31]) is due to tear propagation, while a sec- ondary component could be associated to possible leg extension .
Trouser tear test, bending tests, compression tests, creep tests and several other physical test could be perform for material analysis. 7 . The virtual test method could be quite simple, economical and will shorten the time gap for the new product development process. Polymer films are usually tested for anisotropy (material propertiesA standard two-leg trouser tear test method ( Standard 1993 ) was adopted to check anisotropy in the studied polymers under tearing. The dimensions for the tear specimen is shown in Fig. 1b. The .

ISO 13937-2 describes a single-tear method to determine fabric tear force, known as the trouser test, using a test specimen cut to form trouser-shaped legs. The tear force measured is the force required to propagate a previously started single tear when the force is applied parallel to the cut and the fabric tears in the direction of applied force.
