Električne zobne ščetke - Metode za merjenje funkcionalnosti

Ta dokument obravnava metode za merjenje funkcionalnosti električnih zobnih ščetk.
Ta dokument se uporablja za električne zobne ščetke za umivanje zob, ki jih poganja električna energija. Zobne ščetke z možnostjo ponovnega polnjenja in zobne ščetke, ki delujejo na baterije za enkratno uporabo (za odrasle in otroke) spadajo na področje uporabe tega standarda.
Ta standard zgolj določa metodo za merjenje, vendar ne opredeljuje mejnih vrednosti.
OPOMBA: Električne zobne ščetke so razvrščene na naslednji način:
Razvrstitev glede na vrsto napajanja:
– zobna ščetka, ki deluje na baterije za enkratno uporabo
– zobna ščetka z možnostjo ponovnega polnjenja
– brezžična zobna ščetka z možnostjo ponovnega polnjenja
– zobna ščetka z možnostjo ponovnega polnjenja, ki se napaja iz omrežja
Razvrstitev glede na način premikanja glave ščetke:
– vrtljiva električna zobna ščetka
– električna zobna ščetka s povratnim premikanjem
– linearna električna zobna ščetka s povratnim premikanjem
– rotacijska električna zobna ščetka s povratnim premikanjem
– vibracijska električna zobna ščetka
Različne vrste so pojasnjene zgolj informativno, saj se preskusi, ki jih je treba opraviti, med seboj ne razlikujejo, razen pri zobnih ščetkah, ki delujejo na baterije za enkratno uporabo, in zobnih ščetkah z možnostjo ponovnega polnjenja.

Overview

EN IEC 63174:2022 - Electrically operated toothbrushes - Methods for measuring the performance - specifies standardized measurement methods for assessing the functional performance of electrically operated toothbrushes. Published by CLC and based on IEC 63174:2021, this European/International standard applies to both rechargeable and primary battery powered toothbrushes for adults and children. It defines how to measure performance parameters (not pass/fail limits) so results are comparable across manufacturers and test laboratories.

Key Topics

• Scope & classification

  • Covers electrically operated toothbrushes used to clean teeth by reciprocating, rotating, or vibrating motion.
  • Classifies products by supply mode (primary battery, wireless rechargeable, corded rechargeable) and moving mode (rotary, reciprocated - linear or rotational, vibratory).

• Measured items (Clause 4)

  • Weight of the toothbrush
  • Vibration frequency and rotational speed
  • Hours to fully charge rechargeable toothbrushes
  • Working time after charging or battery replacement
  • Electrical endurance
  • Mechanical endurance (including drop and durability tests)
  • Button operation endurance
  • Stand-by power consumption

• Test conditions & preparation (Clause 5)

  • Standard environmental conditions: 20 °C ± 5 °C, relative humidity 50% (unless otherwise specified).
  • Samples tested under operational conditions described in instructions for use.
  • Rechargeable samples must be fully charged and discharged twice before testing.
  • Power supply for tests must match the specified supply; where multiple supplies exist, use the one yielding the most unfavorable result.

• Measurement specifics

  • Methods for measuring vibration frequency and rotation speed, recording working minutes, and procedures for electrical and mechanical endurance are provided.
  • Stand‑by power measurement references IEC 62301.

Applications

• Manufacturers: design validation, performance benchmarking, and R&D for electric toothbrush models.
• Test laboratories: standardized test methods for issuing performance reports and supporting claims.
• Quality assurance / Production: routine verification of product performance and endurance.
• Regulators & procurement: objective measurement procedures to evaluate product specifications without setting limit values.
• Retailers & consumer insight teams: independent verification of advertised operating time, charging behavior, and durability.

Related Standards

• IEC 62301 - Household electrical appliances - Measurement of standby power (normative reference for measuring stand-by consumption).
• EN IEC 63174 is harmonized with IEC 63174:2021 and intended for use alongside other appliance performance standards developed by IEC/TC 59.

EN IEC 63174:2022 is essential for anyone needing reproducible, comparable performance data for electrically operated toothbrushes - enabling clear communication of product metrics like vibration frequency, charge time, and endurance.

ELECTRICALLY OPERATED TOOTHBRUSHES –
METHODS FOR MEASURING THE PERFORMANCE

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 are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
