CAN/CSA-E335-2-20-94 (R1999) PDF Download

A safety standard specifically for battery-operated toothbrushes and related charging and battery assembly is CAN/CSA-E335-2-20-94 (R1999). It relates to motorized toothbrushes with rechargeable batteries used for home chores and other related uses. Directly connected to the supply line or designed for medical use, these toothbrushes are not covered by the standard.

The guideline notes that there may be particular risks in settings like nurseries or places with young children, elderly people, or infirm people who are not being watched. In such circumstances, extra standards in addition to this standard can be required.

Additionally, it is mentioned that there can be additional specifications for toothbrushes meant for use in cars, boats, or airplanes. Similar conditions might apply to toothbrushes made for use in tropical regions.

The guideline highlights that national health authorities in several countries have established their own unique standards. This implies that the standard only sets forth a minimal set of safety standards and that manufacturers must abide by any additional rules imposed by the health authorities of their individual nations.
