We provide hardness testing services for materials using portable hardness tester.
ITE’s Destructive Testing Lab Division which has been accredited by National Accreditation Board for Testing and Calibration Laboratories (NABL) as per ISO 17025 in the field of Chemical & Mechanical Testing of Metals. This is the highest accreditation granted to laboratories working in the domain of Material Testing and Calibration services.THE TERM HARDNESS, as it is used in industry, may be defined as the ability of a material to resist permanent indentation or deformation when in contact with an indenter under load. Generally a hardness test consists of pressing an indenter of known geometry and mechanical properties into the test material. The hardness of the material is quantified using one of a variety of scales that directly or indirectly indicate the contact pressure involved in deforming the test surface. Since the indenter is pressed into the material during testing, hardness is also viewed as the ability of a material to resist compressive loads. The indenter may be spherical (Brinell test), pyramidal (Vickers and Knoop tests), or conical (Rockwell test). In the Brinell, Vickers, and Knoop tests, hardness value is the load supported by unit area of the indentation, expressed in kilograms per square millimeter (kgf/mm2). In the Rockwell tests, the depth of indentation at a prescribed load is determined and converted to a hardness number (without measurement units), which is inversely related to the depth. Hardness tests are no longer limited to metals, and the currently available tools and procedures cover a vast range of materials including polymers, elastomers, thin films, semiconductors, and ceramics. Hardness measurements as applied to specific classes of materials convey different fundamental aspects of the material. Thus, for metals, hardness is directly proportional to the uniaxial yield stress at the strain imposed by the indentation.
