Introduction

The regulations drafted in accordance with the rules JJF1002-2010 "national verification procedures write rules" given. The procedures in place JJG 113-2003 "standard metal Rockwell hardness blocks (A, B, C, D, E, F, G, H, K, N, T ruler). " Compared with JJG 113-2003, this procedure is mainly technical changes are as follows. --- Modify the standard hardness block uniformity requirements (see Table 2); --- Increasing the standard block special shape required, but not less than the prescribed working face surface area of 2400mm2 (See Table 3); --- Increasing the standard hardness block flatness and parallelism of the test methods (see 6.2.2.2); --- Remove the standard requirements of hardness machine, put it into JJG 112-2013 "Metallic Rockwell hardness Meter "in; --- Test force is applied to modify the primary time (1 ~ 8) s (see 6.2.2.7). The procedures in the development process to fully consider the GB/T 230.1-2009 "metallic materials Rockwell hardness test Test - Part 1. Test methods (A, B, C, D, E, F, G, H, K, N, T scale) ", GB/T 230.3-2002 "metallic materials Rockwell hardness test - Part 3.
