ASTM E10 test method determines Brinell hardness of metallic materials by the Brinell indentation hardness principle. This test method provides the information of metallic materials related to their tensile strength, wear resistance, ductility etc.
The ASTM E10 Brinell hardness test is an indentation hardness test that can provide useful information about physical characteristics of metallic materials and can be useful in quality control and selection of materials. Brinell hardness (HB) is generally used for the soft material, such as non-ferrous metals, steel before heat treated or after annealing. The ASTM E10 Brinell hardness test method is also used for acceptance testing of commercial shipments, and has been used extensively in industry for this purpose.
For ASTM E10, the indenter is brought into contact with the test specimen in a direction perpendicular to the surface, and the test force F is applied. The test force is held for a specified dwell time and then remove it. Brinell Testing Machine is used to support the test specimen and applies an indenting force to a ball in contact with the specimen.The diameter of the indentation is measured in at least two directions perpendicular to each other. The Brinell hardness value is derived from the mean of the diameter. The test is carried out at an ambient temperature within the limits of 10°C to 35°C.
The thickness of the specimen tested should be at least ten times the depth of the indentation h according to ASTM E10.
