ISO 6360-6:2004 specifies the code numbers for specific characteristics of rotary abrasive instruments used 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.

ISO 6360-6:2004 is also applicable to dental polishers which are considered as abrasive instruments.

NOTE In addition to terms for rotary instruments and accessories used in two of the three official ISO languages (English, French and Russian), ISO 6360-6:2004 gives the equivalent terms in the German language; these are published under the responsibility of the member body for Germany (DIN). However, only the terms given in the official languages can be considered as ISO terms.
