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.
