ISO 4547:1993 金属材料 硬度试验 努氏硬度计用标准块的检定

This Intemational Standard specifies a method for the calibration of standardized metal blocks to be used in accordance with ISO 4546 for the indirect verification of Knoop hardness testing machines used for deter- mining Knoop hardness. The method is applicable only for indentations with long diagonals > 20 un1﹜

ISO 4546:1993 金属材料 硬度试验 努氏硬度计的校检

This International Standard specifies a method of verification of testing machines for determining Knoop hardness 'Dr metallic materials in accordance With 9,807 N. The method is applicable only for inden~ tations with diagonals > 20 urn- This International Standard describes a direct verifi- cation method for checking the main functions of the machine, and an indirect verification method suitable for the overall checking of the machine. The indirect verification method may be used on its own for per- iodic routine checking of the machine in service. If a testing machine is also to be used for other methods of hardness testing, it should be verified in- dependently for each method.
