The Rockwell Hardness test is a hardness measurement based on the net increase in depth of impression as a load is applied. Hardness has been variously defined as resistance to local penetration, scratching, machining, wear or abrasion, and yielding. The multiplicity of definitions, and corresponding multiplicity of hardness measuring instruments, together with the lack of a fundamental definition, indicates that hardness may not be a fundamental property of a material, but rather a composite one including yield strength, work hardening, true tensile strength, modulus of elasticity, and others. The Rockwell hardness test method consists of indenting the test material with a diamond cone or hardened steel ball indenter

Interpretation of the results obtained from the risk analysis (see risk analysis), whilst evaluating the public, economic, or political value of the risks involved

Understanding the potential scenarios for an accident or an incident after analysis of the potential risk factors; appraisal of the likelihood of an accident/incident occurring due to the existence of a specific risk factor; appraisal of the possible consequences of the accident/incident if it should happen and integrative computation of the level of danger resulting from the aforementioned appraisal
