What is ASTM E384-22?. The test method in ASTM E384-22 covers determination of the microindentation hardness of materials, which involves using a calibrated machine to force a diamond indenter of specific geometry into the surface of the material being evaluated. This test method is largely applicable to heat treaters, metallographers, .higher. At lower test loads the Vickers hardness may be load-dependent. In Table 2 are given the Vickers hardness numbers for a test load of 1 kgf. For obtaining hardness numbers when other test loads are used, the Vickers hardness number obtained from Table 2 is multiplied by the test load in kilograms-force (Table 3). N. oteThe NG-1000 - Micro Vickers and Knoop Hardness tester is the most advanced hardness tester for accurate measurements and ease of use. The NG-1000 - Micro Vickers and Knoop Hardness tester comes standard with a motorized turret and is available in three (3) different configurations to suit all requirements.
