BS EN ISO 6360-4:2004

BS EN ISO 6360-4:2004 specifies the code numbers for specific characteristics of rotary diamond instruments and diamond-coated discs for use in dentistry. This three-digit number forms the fourth group of three digits in the 15-digit overall number, the principles of which are explained in ISO 6360-1 and ISO 6360-2. This part of ISO 6360 also gives a three-digit number which in addition to the 15-digit code number may be used to provide additional information for diamond instruments and diamond-coated discs, at the discretion of the manufacturer.
