ASTM D2261 Tearing Strength of Textile Fabrics
A large variety of tests are used throughout the textile industry to evaluate the performance and quality of fabrics. ASTM D2261 test method uses the tongue (single rip) procedure to measure the tearing strength of fabrics.
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 jaw move apart and the fabric tears along the precut segment. The resulting data reflects the strength of the yarns, fiber bonds, and fiber interlocks, as well as their resistance to tearing. When testing to this standard, it is important to consider data rate. To consistently and accurately measure the tear strength of your material, it's important to remember that the data sampling rate has to be high enough that the test peaks and troughs are captured. We recommend using either a 3300 or 5900 universal testing machine fitted with pneumatic side action grips. The type of jaw faces varies depending on your material; however we typically recommend rubber or wave profile faces.
We suggest reviewing the standard to fully understand the test setup, procedures, and result requirements.
