4.1x00a0;The Rockwell hardness test is an empirical indentation hardness test that can provide useful information about metallic materials. This information may correlate to tensile strength, wear resistance, ductility, and other physical characteristics of metallic materials, and may be useful in quality control and selection of materials.
4.2x00a0;Rockwell hardness tests are considered satisfactory for acceptance testing of commercial shipments, and have been used extensively in industry for this purpose.
4.3x00a0;Rockwell hardness testing at a specific location on a part may not represent the physical characteristics of the whole part or end product.
4.4x00a0;Adherence to this standard test method provides traceability to national Rockwell hardness standards except as stated otherwise.
1.1x00a0;These test methods cover the determination of the Rockwell hardness and the Rockwell superficial hardness of metallic materials by the Rockwell indentation hardness principle. This standard provides the requirements for Rockwell hardness machines and the procedures for performing Rockwell hardness tests.
1.2x00a0;This standard includes additional requirements in annexes:
Verification of Rockwell Hardness Testing Machines
Annex A1
Rockwell Hardness Standardizing Machines
Annex A2
Standardization of Rockwell Indenters
Annex A3
Standardization of Rockwell Hardness Test Blocks
Annex A4
Guidelines for Determining the Minimum Thickness of a 8199;Test Piece
Annex A5
Hardness Value Corrections When Testing on Convex 8199;Cylindrical Surfaces
Annex A6
