Summary
This standard specifies the method principles, instruments, working conditions and identification steps for identifying copper alloy grades using spectrum analysis methods. This standard is applicable to the identification of copper alloy grades listed in Appendix A. The types of alloy elements and their contents (i.e., mass fraction) of grades other than those listed in Appendix A are within the range defined by the strength standards for determination of the content of each corresponding element in this standard, and may also be used. Refer to this standard for brand identification.
