5 standard

5.1 Standards should be formed similar to the known component is chemically pure metal or alloy or compound with the specimen. 5.2 Preferred samples meet the standards GB/T 4930 requirements, the absence of a suitable standard samples, choose the appropriate research institution recognized standard Samples, but its performance should be close to or in line with GB/T 4930 requirements, and the results shall be stated in the report.

6 Sample

6.1 Analysis of the sample surface should be lapping, polishing, polishing surface microstructure obtained, check the sample surface at 200 to 500 times microscope Analysis of the site should be clean, wear marks and other defects. 6.2 when measured plating or diffusion layer components in cross-section, the specimen shall be inlaid or clamped with a jig and then ground and polished to ensure that the test edge Area without chamfer.
