1.1 ,This test method covers the determination of the force necessary to propagate a tear in plastic film and thin sheeting (thickness of 1 mm (0.04 in.) or less) by a single-tear method. The method is not applicable for film or sheeting material where brittle failures occur during testing.
Note 1: ,Film has been arbitrarily defined as sheeting having nominal thickness not greater than 0.25 mm (0.010 in.).
