Hardness Test Standards

This International Standard specifies the method of the Knoop hardness test for hardmetals.

The standard specifies the method of Vickers hardness test for hardmetals.

This International Standard specifies the method of Vickers hardness test for hardmetals.

Hardness testing with files consists essentially of cutting or abrading the surface of metal parts, and approximating the hardness by the feel, or extent to which, the file bites into the surface. The term "file hard" means that the surface hardness of the parts...

This standard specifies the method of measuring brinell hardness for metallic materials used in GMDAT. In case of brinell hardness measured with a steel ball indenter, apply this standard to HB450 max. and in case of brinell hardness measured with a tungsten carbide alloy ball...

This standard applies to the three cases as follows. In case general method hardness measurement is not impracticable due to too thin carburized depth In case of examining the occurrence of the softened surface to the surface-hardened parts In case of measuring the surface hardness of...

This standard specifies the method of Rockwell A, B, C and Rockwell superficial N and T hardness test for metallic materials mainly used by GMDAT. PURPOSE This standard aims at standardizing works by unifying a using method of Rockwell hardness tester used by GMDAT.

This standard specifies the method of vickers hardness test for matallic materials. In this case, this standard shall be applied to the test load ranging from 0.01kgf to 2kgf.

This method outlines the standard procedure for testing the hardness of bearing components. Bearings covered by this test method shall be any rolling element bearing used in airframe control.

This Standard specifies the method for Rockwell regular and Rockwell superficial hardness tests for metallic materials and is applicable to stationary and portable hardness testing machines For specific materials and/or products like hardmetals, other specific standards...

This method outlines the standard procedure for testing the hardness of bearing components. Bearings covered by this test method shall be any rolling element bearing used in airframe control.

This report lists approximate hardness conversion values; test methods for Vickers Hardness, Brinell Hardness, Rockwell Hardness Rockwell Superficial Hardness, Shore Hardness; and information regarding surface preparation, specimen thickness, effect...

PURPOSE This standard aims at specifying the method of measuring Rockwell M, L and R hardness of plastics. In principle, the range of M, L and R hardness shall be 50 ~ 150. Plastic film tapes and plastic foam are excluded.

This Standard specifies a method for calibration of reference blocks to be used for the indirect verification of Brinell hardness testing machines specified in JIS B 7724 (hereafter referred to as reference blocks). NOTE: The International Standard corresponding to this Standard and...

The ball indentation hardness is the quotient of the major load and the area of indentation produced by a 5 or 10 mm diameter ball after the major load has been applied for the specified time (10 and 60 seconds).
