IEC 60335-2-52:2021 RLV

IEC 60335-2-52:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.

IEC 60335-2-52:2021 deals with the safety of electric oral hygiene appliances for household and similar purposes, their rated voltage being not more than 250 V, including direct current (DC) supplied appliances and battery-operated appliances.
Examples of appliances that this standard is applicable to are
- oral irrigators;
- toothbrushes.
As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account
- persons (including children) whose physical, sensory or mental capabilities, or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
- children playing with the appliance.
Attention is drawn to the fact that
- for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
- in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.
This standard does not apply to appliances for medical purposes (IEC 60601).
This fourth edition cancels and replaces the third edition published in 2002, Amendment 1: 2008 and Amendment 2:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) the text has been aligned with IEC 60335-1:2020;
b) some notes have been converted to normative text (Clause 1, 11.7, 22.101);
c) clarification of requirements for battery-operated appliances (Clause 1, 11.7, B.11.1);
d) application of test probe 19 has been introduced (8.1.1, 20.2);
e) the stability test has been updated to cover hand-held parts of battery-operated appliances when placed on their charging stand (20.1);
f) a drop test is introduced for hand-held parts of an appliance (21.101);
g) additional strength tests for detachable power supply parts are introduced (21.102);
h) Table B.2 and Table B.3 updated to reflect smaller cell capacities for battery-operated appliances covered by this Part 2 standard.
This Part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
