5.3 Because microindentation hardness tests will reveal hardness variations that commonly exist within most materials, a single test value may not be representative of the bulk hardness. Vickers tests at 1000 gf can be utilized for determination of the bulk hardness, but, as for any hardness test, it is recommended that a number of indents are made and the average .ASTM's physical and mechanical testing standards provide guides for the proper procedures employed in the determination of the physical, mechanical, and metallographic properties of certain materials, particularly metals and alloys. .

Standardized optical hardness testing methods include the Brinell hardness test (ISO 6506, ASTM E10), Knoop hardness test (ISO 4545, ASTM E92, ASTM E384) and Vickers hardness test (ISO 6507, ASTM E92, ASTM E384). Alternatively, methods with dynamic force application can also be used within the scope of hardness testing. Note 1: The Vickers and Knoop hardness numbers were originally defined in terms of the test force in kilogram-force (kgf) and the surface area or projected area in millimetres squared (mm 2).Today, the hardness numbers are internationally defined in terms of SI units, that is, the test force in Newtons (N). However, in practice, the most commonly used force .
A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters.

The shank diameter is a standard size for bench-top Brinell hardness testers. 2. 5 mm diameter ball indenters are a good choice when testing material with limited space for measuring or material that is thin and may fracture under heavy loads.I. Significance of Vickers Hardness Standard Test. Vickers hardness test is the nondestructive testing method, which is significant while evaluating materials, a quality check of the manufacturing procedure, and creating new products. Vickers hardness testing method is the only procedure that we can say is universal because of its scaling, as it can be used for .
Rockwell hardness test is one of the static hardness testing methods using indentation depth as a measuring criterion. Basically, two types of indenter are used; one Diamond O spheroconical (Brale) indenter with an angle of 120 and a spherical tip of 0.2mm; second is steel ball indenter with diameters as 1/16, 1/8, 1/4, ½ inches.
