This standard specifies the requirements for dimensions and material properties of shanks used in dentistry for rotary or oscillating instruments. This also includes reciprocating (back-and-forth) instruments. It describes the measurement methods for the verification of the requirements. The shanks are divided into four types. Type 1: RA (angle piece), CA (contra-angle); Type 2: HP (handpiece); Type 3: FG (friction fit). The International Standard has been prepared by ISO/TC 106/SC 4/WG 1 "Dimensions of rotary instruments" (secretariat: DIN) together with CEN/TC 55 "Dentistry" (secretariat: DIN). Working Committee NA 014-00-04 AA "Rotierende Instrumente" ("Rotary instruments") at DIN Standards Committee Dental (NADENT) is responsible.
