Foreword

GB/T 231 "metallic materials Brinell hardness test" is divided into four parts as follows. --- Part 1. Test methods; --- Part 2. Verification and calibration of hardness; --- Part 3. Calibration of hardness reference blocks; --- Part 4. Tables of hardness values. This section GB/T 231 - Part 4. This section equivalent to international standards ISO 6506-4.2005 "metallic materials Brinell hardness test - Part 4. Tables of hardness values" (English Chinese Version). This part of the overall structure, the level of division, the preparation methods and technologies and content ISO 6506-4.2005 is fully consistent and in line with national standards Quasi GB/T 1 "Standardization Guide" series of standards. This section is equivalent to using the international standard ISO 6506-4.2005, there are minor differences in the Editor.
