The tearing strength of textile fabrics by the tongue (single rip) procedure may be determined using the test method specified in ASTM D2261. In this test method, a cut is made in a rectangular specimen, which starts a tear. By cutting the material, two “tongues” are formed. A reference line is drawn to indicate the point to tear. One tongue is placed in the upper jaw and one tongue is placed in the lower jaw. As the test is run, the jaws move apart and the fabric tears along the pre-cut segment.
