    Abstract - (Show below) - (Hide below)

    Sets out requirements for measuring the Brinell hardness of metals and for the installation, calibration and maintenance of the testing machine. It also specifies requirements for the calibration of standard hardness blocks and ball indenters. In this edition, the testing and calibration requirements have been combined into one Standard.

    Scope - (Show below) - (Hide below)

    This Standard sets out methods for measuring the hardness of metals and metal products on scales of Brinell hardness. It includes requirements for the installation and calibration of the testing machine, and recommendations for its maintenance by the user.NOTE: In some Brinell hardness testing machines, the indentation measuring apparatus is integral with the machine. In others, the function of the machine is limited to the indenting process, the measurement of the indentation being made separately. It is acceptable, therefore, for the indenting process to be performed in a compression testing machine which has suitable indenter attachments and which can apply the appropriate force in accordance with this Standard.This Standard does not preclude the use of portable hardness testing machines which meet those requirements of Section 2 which are appropriate to non-portable machines.
