IEC 63174-2021 Electrically operated toothbrushes – Methods for measuring the performance.
This document applies to electrically operated toothbrushes used for electric cleaning of teeth. Rechargeable toothbrushes and primary battery operated toothbrushes, both for adults and children, are within the scope of this document.
This document describes the test methods for measurement of the performance parameters as listed in Clause 4.
The purpose of this document is only to specify the measurement method; it does not define any limit values.
NOTE The electrically operated toothbrushes are classified as follows:
Classification with regard to supply modes:
– primary battery operated toothbrush;
– rechargeable toothbrush:
• wireless rechargeable toothbrush;
• corded rechargeable toothbrush.
Classification with regard to operating modes:
– rotary electrically operated toothbrush;
– reciprocating electrically operated toothbrush:
• linear reciprocating electrically operated toothbrush;
• rotational reciprocating electrically operated toothbrush;
– vibratory electrically operated toothbrush.
The different types are explained for information only, since the tests to be carried out are identical, except for primary battery operated toothbrushes and rechargeable toothbrushes.
