In 1983, fourteen countries participated in a comparison of the Rockwell C scale. The latest worldwide comparison was completed in 1999, covering all Rockwell hardness scales that use a diamond indenter. Although the 1999 comparison showed improved agreement between the world's national hardness ...
Definition of the Rockwell hardness test method The Rockwell hardness test methods are described by a number of scales, characterized by a standard, an indenter type, and a load. Examples of Rockwell hardness test methods: HRE 1/8” diameter tungsten carbide ball indenter, 100 kgf major load ...
certain loads. The hardness of the material is determined by the depth of the indentation. According to the hardness of the test material, three different scales are used to represent the hardness: HRA: the hardness obtained by means of 60kg load and diamond ...
5.1.3 The Rockwell hardness scales are de?ned by the combinations of indenter and test forces that may be used. The standard Rockwell hardness scales and typical applications of the scales are given in Tables 1 and 2. Rockwell hardness values shall be determined and reported in accordance with...
