Overview

EN 60335-2-52:2003 (CLC) is the European adoption of IEC 60335-2-52 and sets particular safety requirements for electric oral hygiene appliances intended for household and similar use, with a rated voltage not more than 250 V. Typical products covered include electric toothbrushes and oral irrigators. This part is intended to be used together with EN 60335-1 (general safety requirements for household electrical appliances) and supplements or modifies Part 1 to address hazards specific to oral hygiene devices.

Key topics and technical requirements

The standard focuses on practical safety and conformity testing. Major topics include:

• Scope & classification: defined appliance types and class distinctions for construction and protection.
• Marking and instructions: required user information and safety warnings for safe operation and maintenance.
• Electrical safety: limits and tests for leakage current, electric strength, transient overvoltages and power input/current considerations.
• Moisture resistance & ingress protection: tests relevant to wet-use appliances (toothbrushes, irrigators).
• Heating and thermal protection: assessment of heating under normal and abnormal conditions.
• Mechanical hazards & stability: evaluation of moving parts, mechanical strength and hand‑held parts.
• Endurance and abnormal operation tests: durability under intended usage and fault conditions.
• Construction & components: internal wiring, components, earthing, screws/connections, clearances and creepage distances.
• Fire and heat resistance: materials and parts resistance to heat, ignition and rusting.
• Radiation, toxicity and similar hazards: ensuring materials and emissions are safe for oral use.

Practical applications

Compliance with EN 60335-2-52 helps manufacturers and stakeholders:

• Design safe electric toothbrushes and oral irrigators for CE marking and European market access.
• Prepare technical files and risk assessments demonstrating conformity with the Low Voltage Directive and related EU requirements.
• Define test plans for product development, type testing and routine production testing in accredited labs.
• Guide procurement, regulatory review and certification activities to reduce safety recalls and liability.

Who uses this standard

• Product designers and R&D engineers for oral hygiene devices
• Compliance managers, regulatory affairs specialists and conformity assessors
• Test laboratories and certification bodies
• Manufacturers, OEMs and suppliers of components for electric oral care products

Related standards

• EN 60335-1 (Household and similar electrical appliances - Safety - Part 1: General requirements)
• IEC 60335-2-52 (international counterpart)
• Applicable EU directives (Low Voltage Directive; Machinery Directive considerations noted in the standard)

Keywords: EN 60335-2-52, oral hygiene appliances safety, electric toothbrush safety, oral irrigators standard, IEC 60335-2-52, household electrical appliances safety.

Foreword
The text of the International Standard IEC 60335-2-52:2002 (61/2221/FDIS), prepared by the
IEC Technical Committee 61, Safety of household and similar electrical appliances, was submitted to
the Unique Acceptance Procedure and was approved by CENELEC as EN 60335-2-52 on

the dates when such changes become applicable will be stated in the relevant amendment or revision
of Part 1.
This part 2 supplements or modifies the corresponding clauses of EN 60335-1, so as to convert it into
the European Standard: Safety requirements for electric oral hygiene appliances.
When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as

Introduction
p Add:
An investigation by CENELEC TC 61 has shown that all risks from products within the scope of this
standard are fully covered by the Low Voltage Directive, 73/23/EEC. For products having mechanical
moving parts, a risk assessment in accordance with the Machinery Directive, 98/37/EC, has shown
that the risks are mainly of electrical origin and consequently this directive is not applicable. However,
the relevant essential safety requirements of the Machinery Directive are covered by this standard
together with the principal objectives of the Low Voltage Directive.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts a
