If the initial slit is made in the machine direction, the result is given as machine direction tearing resistance and similarly for the cross-machine direction (ISO 1974). Why measure tearing resistance?
The tensile strength of a material is the maximum mechanical tension it can withstand before it cracks. It is given in N/mm² or MPa. The tear resistance of a material, also called tensile strength at break, is the mechanical tensile stress at the exact moment of tearing and is also given in N/mm² or MPa.. Since the maximum tensile stress and the tensile stress at the moment of . TEAR RESISTANCE Tear resistance testing measures the strength of a material when subjected to a point of rupture.

The ASTM D 1922 Tear Resistance test method covers the determination of the average force to propagate tearing through a specified length of plastic film or nonrigid sheeting after the tear has been started, using an Elmendorf-type tearing tester. Two specimens are cited, a rectangular type, and one with a constant radius testing length.General paper property that takes into account two measures of a paper's ability to withstand being torn. Internal tearing resistance refers to the work required to tear a paper sample through a specified distance once the tear has been started. Edge tearing resistance refers to the work required to tear a paper sample by starting the tear at the edges of the sheet.ASTM D1922 Elmendorf Tear Test Scope: All plastic films and sheets are prone to tear with increased force. The ASTM D1922 test method is widely used to rank the relative tear resistance of thin plastic films and sheets. The pendulum impact tester determines the minimum force required for an existing slit to propagate through a [.]During this test the sample geometry produces stress levels in a small region of the sample and then the ultimate stress is recorded as tear resistance in newtons (or pounds-force), typically at the beginning of tearing.
