This part of ISO 6360 specifies the code numbers for specific characteristics of mandrels and special
instruments such as bone cutters, implant burs, trephines, wax scrapers and polishers. 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.
NOTE In addition to terms for rotary instruments and accessories used in two of the three official ISO languages (English, French and Russian), this part of ISO 6360 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.
