標準正文
1. Scope
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 E10 or
E18 hardness tester.
1.2 The principles used to measure the Rockwell or Brinell
hardness are the same as those defined in the E18 standard test
method for Rockwell or E10 standard test method for Brinell.
NOTE 1—Standard test methods E10 and E18 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 E10 or E18 For example, this
test method does not apply to the methods defined in ASTM
standard Practice A833, Test Methods A956 and A1038 or
B647.
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 Annex A1 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.
