UNE-EN ISO 20127:2026

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 powered toothbrushes. Common features of those powered toothbrushes

to which this document applies are:

a battery;

a motor;

a mechanical or magnetic drive system;

a moving brush head with tufted filaments.

Powered toothbrushes can have a moving brush head with different motions (e.g. oscillating-rotating, sideby-

side), frequencies and velocities.

The requirements listed in this document apply to all types of powered toothbrushes. However, there is a

possibility that some requirements are not applicable for all types, for example brush head plate retention

can only be applied if the brush has a head portion that might get detached from the brush shaft. In addition,

for the filaments end-rounding requirements, this document does not apply to particular filament types

which are very thin (less than 0,1 mm outside diameter) or have no sharp edges (e.g. tapered, feathered,

with split tips, or spherical cap) or non-synthetic filaments, where applying end-rounding process is

inappropriate or impossible.

This document is not applicable to other types of powered oral hygiene devices (such as powered interdental

brushes) or manual toothbrushes.
