It is also applicable for super abrasives with vitrified or metal core having the same diameters as the grinding wheels according to those parts of ISO 603, independently from the material of the core. It applies to grinding wheels with peripheral speeds up to 50 m/s and driving powers of the wheel spindle up to 30 kW. It is not applicable to mounting devices for cutting-off wheels.
