Overview

IEC 60704-2-9:2003 is an international standard issued by the International Electrotechnical Commission (IEC), focusing on the determination of airborne acoustical noise from household and similar electrical appliances. Specifically, Part 2-9 defines particular requirements for electric hair care appliances such as hand-held hairdryers and hairstyling devices that operate with airflow generated by a fan. This standard does not cover hair care appliances using radiant heating or helmet-type hairdryers.

Designed to be used alongside IEC 60704-1:1997, which establishes general requirements for noise measurement, IEC 60704-2-9 provides a test code tailored to the unique acoustic testing challenges of electric hair care appliances. It ensures precise and repeatable noise measurements, facilitating reliable comparison of acoustic emissions between products and across testing laboratories worldwide.

Key Topics

  • Scope: Targets electrically powered, hand-held hairdryers and similar airflow-producing devices powered from the mains supply for household and similar use.
  • Measurement Methods: Specifies conditions and procedures for acoustic noise measurement that realistically simulate practical usage.
  • Test Instrumentation & Setup: Details apparatus and environmental conditions required for valid and consistent noise measurements.
  • Operating Conditions: Defines the positioning and operational mode of appliances during testing to mimic typical consumer use.
  • Sound Pressure and Power Levels: Provides procedures to measure and calculate sound pressure levels and sound power levels accurately.
  • Recording & Reporting: Identifies the specific data and test parameters that must be recorded and documented in conformity reports.
  • Standardized Test Table: Includes a normative annex with the recommended test conditions essential for consistent noise testing.
  • Relationship to IEC 60704-1: Supplements and modifies relevant parts of the general test code with appliance-specific requirements.

Applications

IEC 60704-2-9 is essential for:

  • Manufacturers developing or refining electric hair care appliances to ensure products meet standardized noise emission criteria.
  • Testing Laboratories conducting acoustical noise assessments, enabling consistent measurement and reporting of appliance noise emissions.
  • Regulators and Certification Bodies seeking to enforce noise limits or certify performance claims related to electric hair care appliances.
  • Quality Assurance Teams monitoring production compliance with international noise standards.
  • Consumer Safety and Comfort: Assisting in providing products that comply with noise emission levels to enhance user comfort and reduce acoustic pollution during use.

By adhering to IEC 60704-2-9, stakeholders can ensure that noise emissions from hairdryers and similar devices are evaluated precisely, supporting product development that balances performance and noise control.

AVANT-PROPOS
1) La CEI (Commission Électrotechnique Internationale) est une organisation mondiale de normalisation composée
de l'ensemble des comités électrotechniques nationaux (Comités nationaux de la CEI). La CEI a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l'électricité et de l'électronique. A cet effet, la CEI, entre autres activités, publie des Normes internationales.
Leur élaboration est confiée à des comités d'études, aux travaux desquels tout Comité national intéressé par le
sujet traité peut participer. Les organisations internationales, gouvernementales et non gouvernementales, en
liaison avec la CEI, participent également aux travaux. La CEI collabore étroitement avec l'Organisation
Internationale de Normalisation (ISO), selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de la CEI concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux intéressés
sont représentés dans chaque comité d’études.
3) Les documents produits se présentent sous la forme de recommandations internationales. Ils sont publiés
comme normes, spécifications techniques, rapports techniques ou guides et agréés comme tels par les Comités
nationaux.
4) Dans le but d'encourager l'unification internationale, les Comités nationaux de la CEI s'engagent à appliquer de
façon transparente, dans toute la mesure possible, les Normes internationales de la CEI dans leurs normes
nationales et régionales. Toute divergence entre la norme de la CEI et la norme nationale ou régionale
correspondante doit être indiquée en termes clairs dans cette dernière.
5) La CEI n’a fixé aucune procédure concernant le marquage comme indication d’approbation et sa responsabilité
n’est pas engagée quand un matériel est déclaré conforme à l’une de ses normes.
6) L’attention est attirée sur le fait que certains des éléments de la présente Norme internationale peuvent faire
l’objet de droits de propriété intellectuelle ou de droits analogues. La CEI ne saurait être tenue pour
responsable de ne pas avoir identifié de tels droits de propriété et de ne pas avoir signalé leur existence.

FOREWORD
1) The IEC (International Electrotechnical Commission) 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, the IEC publishes International Standards. 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 liasing
with the IEC also participate in this preparation. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

The article discusses the application of the IEC 60704-2-9 standard, which pertains to the testing of airborne acoustical noise in household and similar electrical appliances. Specifically, the standard applies to hand-held hairdryers that are powered by mains electricity and operate using a flow of air. It can also be applied to similar devices like hairstyling appliances that use a fan to produce the airflow. However, the standard does not apply to hair care appliances with radiant heating and helmet-type hairdryers.
