Specifies conversion bands for hardness scales for Vickers/Brinell (steel ball and hardmetal ball), and Vickers/Rockwell (scales A, B, C and D). This conversion bands only apply to non-alloy and low-alloy steels for products of homogeneous structure and of thickness equal to or greater than the figure given in the relevant test standard. In cases of dispute the hardness value obtained from the hardness test should be used. Converted hardness values shall not be used as a basis for rejection of the steel.
