Wilson hardness reference plate
100% inspection to ensure that various hardness reference pieces meet ASTM physical requirements!
The "Wilson Hardness Reference Plates" have a comprehensive range of scales and types of hardness reference plates, making them suitable for a wide range of hardness scales related to Rockwell, Brinell, Knoop, and Vickers tests. They are made from the highest quality materials to ensure that industry standards are set, and that highly invariant and reproducible hardness reference plates can be obtained. The testing machines used in the calibration process are subjected to a rigorous monitoring process using NIST-traceable equipment. 【Features】 ■ Direct collaboration with steel mills to identify chemical composition ■ All machining (grinding, lapping, polishing) is performed in-house at calibration facilities ■ 100% inspection to ensure various hardness reference plates meet ASTM physical requirements (thickness, flatness, parallelism, surface roughness) *For more details, please refer to the PDF document or feel free to contact us.
