本文件规定了电动牙刷物理性能的要求和试验方法，以提高这些产品在预期用途中的安全性。 电动牙刷有不同的技术。 本文件适用的电动牙刷的共同特点是: -电池； -马达； -机械或磁力驱动系统； -有簇状细丝的移动刷头。 电动牙刷可以有一个移动的刷子 头部具有不同的运动（例如摆动旋转、并排旋转）、频率和速度。 本文件中列出的要求适用于所有类型的电动牙刷。但是，有可能有些要求 不适用于所有类型，例如，只有当电刷的头部部分可能从电刷轴上脱落时，才可以使用电刷头板固定装置。 本文件不适用于其他类型的动力口服液 卫生设备（如电动齿间刷）或手动牙刷。

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, side-by-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. This document is not applicable to other types of powered oral hygiene devices (such as powered interdental brushes) or manual toothbrushes.
