GB/T 17365-1998

This standard specifies the procedures for preparing metal and alloy samples for quantitative electron probe microanalysis (EPMA). It is applied in materials science laboratories and quality control settings to ensure sample surfaces are flat, polished, and contamination-free, enabling accurate elemental composition analysis of metals and alloys. The method is critical for industries such as metallurgy, aerospace, and manufacturing where precise micro-scale chemical characterization is required.
