适用范围：This part of ISO 6508 specifies the method for Rockwell and Rockwell superficial hardness tests (scales andfield of application according to Table 1) for metallic materials.Attention is drawn to the fact that, in this part of ISO 6508, the use of hardmetal for ball indenters isconsidered to be the standard type of Rockwell indenter ball. Steel indenter balls may be continued to be usedif specified in a product specification, or by special agreement.NOTE 1 Attention is drawn to the fact that results obtained with hardmetal balls can be significantly different than whenusing a steel ball. For specific materials and/or products, other specific International Standards apply (for instanceISO 3738-1 and ISO 4498-1).NOTE 2 For certain materials, the fields of application may be narrower than those indicated.
