Scope

This Standard specifies the terms and definitions, classification, expected performance,
performance attributes, performance evaluation, production, repetitive processing
tolerance, information and test methods provided by the manufacturer of torque
transmitters. This type of torque transmitter is used as an auxiliary device to be
connected to a dental handpiece, which is used to place oral implants during oral
implant surgeries and perform further operations on the connecting parts in the
craniofacial region.
This Standard is applicable to torque transmitters that implant implants into or remove
implants from the patient’s oral cavity. The torque transmitter is connected to a power-
driven system equipped with a torque control function. This Standard does not include
dental implants or components connected to dental implants.
This Standard is not applicable to the power-driven system itself.
