Preface:

This is the first edition of CAN/CSA-C22.2 No. 60335-2-52, Household and similar electrical appliances - Safety - Part 2-52: Particular requirements for oral hygiene appliances, which is an adoption, with Canadian deviations, of the identically titled IEC (International Electrotechnical Commission) Standard 60335-2-52 (edition 3:2002 consolidated with Amendment 1:2008). It replaces the previous edition, published in 2001 as CAN/CSA-E60335-2-52 (adopted IEC 335-2-52:1994). It also replaces the requirements for dental irrigators found in CSA C22.2 No. 68-09, Motor-operated appliances (household and commercial). CSA C22.2 No. 68-09 continues to apply to other motor-operated appliances.

For brevity, this Standard will be referred to as "CAN/CSA-C22.2 No. 60335-2-52" throughout. This Standard is intended to be used in conjunction with CAN/CSA-C22.2 No. 60335-1-11, Safety of Household and Similar Appliances - Part 1: General Requirements (adopted IEC 60335-1:2001 + A1:2004 + A2:2006, with Canadian deviations).

This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Consumer and Commercial Products, under the jurisdiction of the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada.

Scope:

This International Standard deals with the safety of electric oral hygiene appliances for household and similar purposes, their rated voltage being not more than 250 V.

NOTE 101 Examples of appliances covered by this standard 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.

NOTE 102 Attention is drawn to the fact that

• for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may 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.

NOTE 103 This standard does not apply to appliances for medical purposes (IEC 60601).
