ISO 1797:2017 specifies the requirements for dimensions and material properties of shanks used in dentistry for rotary or oscillating instruments. It describes the measurement methods for the verification of the requirements. ISO 1797:2017 is not applicable to tips fixed to the handpiece with a screw, e.g. scaler tips. Information about the location of marking is also given. Annex A on quality control is included in order to ensure a high quality level.
