ISO 6506-4:2014 pdf free.Metallic materials – Brinell hardness test – Table of hardness values
See Tables 1 and 2. Where the measured indentation diameter value is not given in the table, a linear interpolation between the two adjacent values and between the two corresponding hardness values should be carried out. Each hardness value is quoted to three significant figures, but is calculated from the nominal force-diameter index rather than from the specified force value, in order to avoid variations in the hardness values calculated at a specific force-diameter index. In some cases, this calculation method leads to an error of one digit in the least significant figure.
