Indentation hardness tests are used in mechanical engineering to determine the hardness of a material to deformation. Several such tests exist, wherein the examined material is indented until an impression is formed; these tests can be performed on a macroscopic or microscopic scale. When testing metals, indentation hardness correlates roughly linearly with tensile strength, but it is an imperfect correlation often limited to small ranges of strength and hardness for each indentat… SpletShore - HS; Vickers - HV; Each of these scales involve the use of a specifically shaped diamond, carbide or hardened steel indenter pressed into the material with a known force using a defined test procedure. The hardness values are determined by measuring either the depth of indenter penetration or the size of the resultant indent. All of the ...

SpletThe most widely used device is a shore hardness meter. The hardness is measured by the depth of indentation caused by a rigid ball under a spring load or dead load, the indentation being converted to hardness degrees on a scale ranging from 0 to 100. The reading from a dead load hardness meter is called International Rubber Hardness Degrees (IRHD). SpletAbstract. This part of ISO 2039 specifies a method for determining the hardness of plastics and ebonite by means of a. loaded ball indenter. The ball indentation hardness determined by this method may provide data for research and development, quality. control and acceptance or rejection under specifications.
