Knoop hardness to vickers conversion
WebVickers and Knoop hardness tests should be carried out at a temperature within the limits of 10 to 35°C (50 to 95°F). Because variations within this temperature range may affect results, users may choose to control tempera- true within a tighter range. PRINCIPLE OF THE VICKERS HARDNESS TEST INDENTER VICKERS WebThe Knoop hardness test method, also referred to as a microhardness test method, is mostly used for small parts, thin sections, or case depth work. The Vickers method is based on an optical measurement system.
