1.1 This test method defines the requirements for portable instruments that are intended to be used to measure the Rockwell or Brinell hardness of metallic materials by performing indentation tests on the surface of materials in the field or outside of a test lab, or in cases where the size or weight of the test piece prevents it from being tested on a standard or hardness tester.
1.2 The principles used to measure the Rockwell or Brinell hardness are the same as those defined in the standard test method for Rockwell or standard test method for Brinell.
Note 1: Standard test methods and will be referred to in this test method as the standard methods.
1.3 The portable hardness testers covered by this test method are verified only by the indirect verification method. Although the portable hardness testers are designed to employ the same test conditions as those defined in the standard test methods, the forces applied by the portable Rockwell and Brinell testers and the depth measuring systems of the portable Rockwell testers may not meet the tolerance requirements of the standard methods. Portable hardness testers shall use indenters that meet the requirements of the standard test methods.
1.4 This test method does not apply to portable hardness testers that measure hardness by a means or procedure that is different than those defined in or For example, this test method does not apply to the methods defined in ASTM standard Practice , Test Methods and or .
1.5 A report section is included to define how to indicate that the test result was obtained by using a portable device that conforms to this document.
1.6 is included that defines the periodic indirect verification and daily verification requirements for these instruments.
1.7 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.
