GB/T 2490-2007 《Bonded abrasive products - Hardness grade measurement》 Related products

GB/T 2490-2007 regulates the Hardness inspection of consolidated abrasives. Hardness of consolidated abrasives affects its grinding performance and service life. The standard specifies the applicable types of consolidated abrasives products, specifies the selection and calibrating requirements of Hardness inspection equipment. Detail the preparation of abrasive samples before inspection to ensure that they meet the test conditions. Standardize the specific operation process of Hardness inspection, including the method of applying force, the selection of measurement points, etc. At the same time, give the evaluation and representation method of inspection results. Provide a unified standard for accurately judging the Hardness of consolidated abrasives, help manufacturers control the mass of products, and ensure the stable and efficient application of abrasives in industrial processing.
