ASTM E110-10

Standard Test Method for Indentation Hardness of Metallic Materials by Portable Hardness Testers

ABSTRACT
This test method establishes the standard procedures, including the calibration, precision and bias of the apparatus used, for the determination of indentation hardness of metallic materials by means of portable hardness testers.
SCOPE
1.1 This test method covers determination of the indentation hardness of metallic materials by means of portable hardness testers.
1.2 This test method applies only to those portable hardness testers which apply the same nominal forces and use the same indenters as are used in the methods listed in Section 2.
1.3 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.

3. Apparatus
3.1 Portable hardness testers are used principally for testing articles that are too large or unwieldy to be tested in the usual types
of testing machines, for testing parts of fixed structures, or for testing under any conditions which require that the indenting force
be applied in a direction other than vertical. In order that they may be portable and also in order that the indenting forces may be
applied in any direction, these testers are designed in such a way that dead weights are not used in applying or limiting the
indenting force.
3.2 The indenting force may be applied by means of a hydraulic cylinder with a pressure gage to indicate the magnitude of the
force. The hydraulic cylinder may also be equipped with a spring-forceed relief valve to fix the magnitude of the force.
Alternatively the indenting force may be applied by means of a screw through a calibrated spring with a dial gage or other means
of measuring the deflection of the spring to indicate the magnitude of the force.
3.3 Portable hardness testers are generally provided with various means of holding the indenter in contact with the surface to
