Application Summary AI generated
This standard specifies the method for performing Knoop hardness tests on metallic materials, defining the test principle, indenter specifications, and calculation procedures for the Knoop hardness value. It is applied in metallurgical laboratories and quality control settings to evaluate the hardness of thin layers, small or brittle metallic components, and surface-treated materials, where a shallow indentation is required to minimize damage. The standard is particularly relevant for industries such as aerospace, automotive, and precision engineering, where material hardness must be assessed on micro-samples or coatings.
