This standard specifies specific requirements for shanks for rotary instruments used in dentistry and gives measurement methods for the verification of dimensions. The shanks for rotary instruments are classified into four types. 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). The responsible committee at DIN is Working Committee NA 014-00-04 AA "Rotierende Instrumente" ("Rotary instruments") at NADENT. The substantial modifications with respect to DIN EN ISO 1797-1:1999 are the specification of a maximum value of 1 mm for the end of the shank for Type 3 shank and the requirement for the shank cylindricity.
