Hardness tester rental equipment evaluates a material's strength, ductility, and resistance. This results in the determination of whether that material is suitable for a project or if other options need to be considered. Hardness testing is defined as determining the resistance a material performs to permanent deformation by another harder material. Because hardness is a subjective quality, hardness should be judged in relation to specific loads on the indenter, indenter geometry, and loading time profiles.
Hardness tests usually involve pressing specifically dimensioned indenters into the surface of the material. Hardness can be determined either by measuring the depth of the indenter penetration or the measurement of the impression created by the indenter. When selecting a portable hardness tester rental, considerations to be made along with the device used for testing include the material itself, its homogeneity, size, and the required accuracy of the result. Rockwell, Knoop, Brinell, and Vickers are the most well known types of hardness tests.
