CUTTING THE MARK Degree of hardness The hardness grade is specified with the letters A to Z. The hardness increases fromAto Z. Key The key contains company-internal information. Abrasive grain AStandard aluminium oxide ZZirconium CSilicon carbide For graduations within the individual grain qualities, numbers may be added in front of the letter for the abrasive grain, e.g.: 30A Semi-friable aluminium oxide 54A Pink aluminium oxide 56A White aluminium oxide 89A Special aluminium oxide Structure The structure is identified by the numbers 0 to 14. The higher the number, the more open the structure, and the more porous the abrasive. Bonding types B Synthetic resin bonding BF Fibre-reinforced synthetic resin bonding Grain size Grain size in MESH acc. to FEPA standard: 04to 24 coarse 30to 60 Medium 70to 220 fine Material symbols for the material to be processed: Stainless steel/steel Steel Non-ferrous metals Cast iron Stone CUTTING THE LABEL Dimensions in mm and inches Disc width Disc diameter in mm 1 Safety pictograms See overview on fold-out at end of catalogue 2Material pictograms See overview on fold-out at end of catalogue 3Traceability code 4Info ring with expiry date 5Name of manufacturer 6ISO reference see p. 025 7EAN barcode 8oSa mark see p. 014 9 European standard for bonded abrasive products 10Maximal permissible working speed see p. 024 11Part number 12Product reference Quality reference Colour coding system 1 2 5 × 1.0 025
