WitrynaBefore looking at impact testing let us first define what is meant by 'toughness' since the impact test is only one method by which this material property is measured. Toughness is, broadly, a measure of the amount of energy required to cause an item - a test piece or a bridge or a pressure vessel - to fracture and fail. WitrynaHardness tests on metals are performed according to the following common static methods, which are defined in the standards (ISO vs. ASTM) listed below: The following methods are used for hardness tests on rubber-elastic polymers and elastomers: Categorization of hardness tests according to load ranges
