ISO 6383-1 Tear Resistance Plastic Film and Sheeting
This method is used to investigate the tear resistance of plastic films or sheets, less than 1 mm thick, in the form of a standard trouser-shaped test specimen. The ISO 6383-1 test method is suitable for use with:
Film and sheeting of both flexible and rigid materials, provided that the material is not so rigid that a brittle fracture occurs during the test.
In principle, the test specimen is carefully clamped and aligned with the specimen legs in the grips so that the major axis coincides with an imaginary line joining the center of the grips. This is pulled apart until failure at a constant rate of displacement. The load is recorded as the tear propagates through the entire unslitlength of the specimen. The average force required to tear the specimen completely along its length is used to calculate the tear resistance of the material.
We use screw action grips, pneumatic action grips with rubber coated jaw faces for clamping of the material fitted to a tensile testing machine, normally a single-column or dual-column table-top design. Using a materials testing software, such as Bluehill®, allows you to input specimen details, set the desired test control, automatically calculate the desired results and statistics, and produce a test report all in accordance with the standard.
We suggest reviewing ISO 6383-1 to fully understand the test fixture and results requirements

Screw side-action grips provide a very simple and efficient method for holding test specimens in a wide range of applications. The dual - acting design of 2710-100 series grips means that jaw faces can be adjusted to accommodate different specimen thicknesses. This ensures that the line of tensile force remains concentric with the grip body. They can be equipped with a selection of interchangeable grip jaw faces in various sizes and choice of surfaces including smooth ground, rubber-coated and serrated. Line contact and special coated faces are also available.The unique ‘snap-on’ jaw face attachment makes changing faces extremely quick and simple.
