We present the results of research on the improvement of GET 30-94, the State Primary Standard of hardness on the Rockwell and Super Rockwell scales. The upgraded nodes of the standard are presented, its metrological characteristics are improved, the budget of the measurement uncertainty is calculated for reproducing the hardness numbers on the Rockwell and Super Rockwell scales. In the process of improving the standard, 15 hardness scales, previously not used in Russia, were introduced. The approved the State Primary Standard of hardness on the scale of Rockwell and Super Rockwell GET 30-2018 corresponds to the best world analogues.
