How should the indentation after Vickers hardness test HV be handled?

The treatment of indentations after measurement with a Vickers hardness tester (HV) depends on the purpose of the specimen and subsequent processing requirements.
For specimens that need to be preserved, such as samples used for archiving, secondary inspection, or display, the indentation should be kept as intact as possible, avoiding wiping or grinding; a protective cover can be used to shield the specimen to prevent the indentation from being contaminated or damaged. If the specimen requires subsequent processing, as the location of the indentation may affect processing precision, methods such as grinding or polishing can be used to remove the indentation, but care must be taken during operation to avoid damaging other parts of the specimen.
For discarded specimens after batch testing, they can be treated as general industrial waste, provided that environmental protection regulations are observed.
In addition, when recording measurement data, information such as the location and size of the indentation should be labeled in detail to facilitate subsequent traceability.
When handling indentations, never use hard objects to scrape them, so as to avoid destroying the specimen surface or causing indentation deformation, which would affect the reliability of the data.
