Standard Test Method for Dynamic Tear Testing of Metallic Materials
|Publication Date:||1 December 2015|
|ICS Code (Mechanical testing of metals):||77.040.10|
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.
This test method is applicable to materials with a minimum thickness of 3⁄16 in. (5 mm).
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.
