Metallic materials — Vickers hardness test — Part 4: Tables of hardness values. Metallic materials — Vickers hardness test — Part 4: Tables of hardness values. Identifying the resistance to indentation helps determine the strength and heat treat condition of a material used within the industrial design process. NOTE 1 For indentation diagonals less than 0,020 mm, the increase of the uncertainty has to be considered. Skip to main content. ASTM E 384 (For Micro-indentation) ASTM E 92 (For Macro-indentation) ISO 6507; Vicker Hardness Test Theory. Principle. Standards for Vickers Hardness test. The Vickers hardness test is often regarded as easier to use than other hardness tests: The process can be performed on a universal or micro hardness tester; the required calculations are independent of the size of the indenter; and the same indenter (a pyramidal diamond) can be used for all materials, irrespective of hardness. The testing, measurement, and analysis of the hardness of a metal is critical. ... International Standard under periodical review 90.60 2008-06-18. The Vickers hardness test is specified in this part of ISO 6507 for lengths of indentation diagonals between 0,020 mm and 1,400 mm. The Vickers hardness test has two distinct force ranges, “Microindentation Vickers” (10 - 1000g) and “Macroindentation Vickers” (1 - 100kg), to cover all testing requirements. The indenter is the same for both ranges; therefore Vickers hardness values are continuous over the total range of hardness for met- als (typically HV100 - HV1000). Following are the standards for Vickers Hardness test, which describes the testing procedure and its specifications. Menu.
