Standard Test Method for Dynamic Tear Testing of Metallic Materials
|Publication Date:||25 March 1983|
|ICS Code (Mechanical testing of metals):||77.040.10|
1.1 This test method covers the dynamic tear (DT) test using specimens that are 3/16 in. to ⅝ in. (5 mm to 16 mm) inclusive in thickness.1
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 E 18.
