scope:

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 E 18.

1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
