This part of ASTM D 624-00 specifies the test conditions for measuring a property of conventional vulcanized rubber and thermoplastic elastomers called tear strength. This standard consists of two separate test methods. Test Method A is a tear test for Die A, Die B and Die C crescent specimens; Test Method B is a T-Peel test for type T and CP rectangular specimens. The resistance to tear is calculated from the peak or maximum force and thickness. Similar to an elastomeric tension test, pneumatic side acting grips along with either serrated or rubber coated jaw faces are the preferred gripping solution for testing to this standard.
