prEN ISO 20127

This document specifies requirements and test methods for the physical properties of powered toothbrushes in order to promote the safety of these products for their intended use. There are different technologies of power toothbrushes. Common features of those powered toothbrushes for which this document applies:
— a battery;
— a motor;
— a mechanical or magnetic drive system;
— a moving brush head with tufts.
Power toothbrushes may have different motions of the moving brush head (e.g. oscillating-rotating, side-by-side) and may have different frequencies and velocities for the moving brush head.
The requirements listed in this document shall be fulfilled for all types of power toothbrushes if applicable. However, some requirements may not be applicable for all types, e.g. brush head retention can only be applied if the brush has a head portion that might get detached from the brush tube.
Excluded are other types of powered oral hygiene devices (such as powered interdental brushes) and manual toothbrushes.
