Richter hardness tester is a kind of testing equipment. In field work, bending specimens are often encountered, and various curved surfaces have different effects on the hardness test results. In the case of correct operation, the impact position of the specimen surface is the same as that of the flat specimen, so the universal support ring can be used. However, when the curvature is small to a certain size, the rebound speed of the impact body will be low because of the significant difference in elastic state of deformation under plane conditions, thus making the Richter hardness lower. Therefore, for samples, it is recommended to use a small support ring when measuring. For samples with small radius of curvature, it is suggested to choose special-shaped support ring.
