|Publication Date:||1 January 1994|
1.1 This test method covers the dynamic tear (DT) test using specimens that are 3/16 in. to 5/8 in. (5 mm to 16 mm) inclusive in thickness.
1.2 This test method is applicable to materials with a minimum thickness of 3/16 in. (5 mm).
1.3 The pressed-knife procedure described for sharpening the notch tip generally limits this test method to materials with a hardness level less than 36 HRC.
Note 1-The designation 36 HRC is a Rockwell hardness number of 36 on Rockwell C scale as defined in Test Methods E18.
