1 Scope This part of GB/T 231 specifies the principle, symbols and abbreviated terms, apparatus, test piece, procedure, uncertainty of the results and test report for the Brinell hardness test for metallic materials. This part specifies the Brinell hardness test is up to the limit of 650 HBW. For Brinell hardness test of specific materials or products, shall be specified in particular standards. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of GB/T 231. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
