Household and similar electrical appliances - Safety - Part 2-68: Particular requirements for spray extraction machines, for commercial use
IEC 60335-2-68:2012 deals with the safety of electrical portable, non-self-propelled motor-operated spray extraction machines with or without attachments and with or without electrical heating elements, intended for commercial indoor use. This standard applies to machines for commercial use. The following list, although not comprehensive, gives an indication of locations that are included in the scope:
- public use areas such as hotels, schools, hospitals;
- industrial locations, for example factories and manufacturing shops;
- retail outlets, for example shops and supermarkets;
- business premises, for example offices and banks;
- rental services for those machines and all uses other than normal housekeeping purposes.
They are not equipped with a traction drive. The following power systems are covered: mains powered motors up to a rated voltage of 250 V for single-phase appliances and 480 V for other appliances and battery powered motors. This standard applies to machines in which the pressure of the employed cleaning agent does not exceed 2,5 MPa, and in which the product of the pressure (in MPa) and the flow of cleaning agent (in litres per minute) does not exceed 100, and in which the temperature of the cleaning agent at the spray nozzle outlet does not exceed 85 °C. This fourth edition cancels and replaces the third edition published in 2002 and its Amendments 1 (2005) and 2 (2007). It constitutes a technical revision. The principal changes in this edition as compared with the third edition of IEC 60335-2-68 are as follows (minor changes are not listed):
- the title has been changed for better distinction with regard to IEC 60335-2-72;
- the scope has been revised editorially to avoid misunderstandings;
- terms and definitions has been revised with regard to the requirements revised;
- the standard has been revised in general and updated regarding state-of-the-art, as far as necessary, in particular some changes has been made to Clauses 15, 22 and 25;
- the markings and instructions (Clause 7) have been revised basically;
- a new Annex AA 'Emission of acoustical noise' was added;
- and a new Annex BB 'Emission of vibration' was added. Keywords: Spray extraction machines; cleaning agent.
This publication is to be read in conjunction with IEC 60335-1:2010.
Appareils électrodomestiques et analogues - Sécurité - Partie 2-68: Exigences particulières pour les machines de nettoyage par pulvérisation et aspiration, à usage commercial
La CEI 60335-2-68:2012 traite de la sécurité des machines de nettoyage par pulvérisation et aspiration électriques mobiles non auto-motrices, avec ou sans accessoires et avec ou sans éléments chauffants électriques, destinées à un usage commercial à l'intérieur des locaux. La présente norme s'applique aux machines à usage commercial. La liste suivante, sans être exhaustive, donne une indication des emplacements compris dans le domaine d'application:
- espaces publics tels que les hôtels, les écoles, les hôpitaux;
- sites industriels, par exemple les usines et les ateliers de fabrication;
- commerces, par exemple les magasins de détail et les supermarchés;
- établissements commerciaux, par exemple les bureaux et les banques;
- services de location pour ces machines;
- toute utilisation autre que les utilisations domestiques normales. Ces machines ne possèdent pas de dispositif de transmission. Les systèmes d'alimentation électrique suivants sont couverts: moteurs alimentés par le réseau jusqu'à une tension assignée de 250 V pour les appareils monophasés et 480 V pour les autres appareils, moteurs alimentés par batteries. La présente norme s'applique aux machines dans lesquelles la pression de l'agent nettoyant ne dépasse pas 2,5 MPa ou dont le produit de la pression (en MPa) de l'agent nettoyant par son débit (en litres par minute) n'excède pas 100, et dans lesquelles la température de l'agent nettoyant à la sortie de la buse n'excède pas 85 °C. Cette quatrième édition annule et remplace la troisième édition publiée en 2002 et ses Amendements 1 (2005) et 2 (2007). Elle constitue une révision technique. Les principales modifications de la présente édition par rapport à la troisième édition de la CEI 60335-2-68 sont les suivantes (les changements mineurs ne sont pas listés):
- le titre a été modifié pour une meilleure distinction d'avec la CEI 60335-2-72;
- le domaine d'application a fait l'objet d'une révision éditoriale afin d'éviter toute erreur d'interprétation;
- les termes et définitions ont été révisés par rapport aux exigences révisées;
- la norme a été révisée de manière générale et mise à jour au regard de l'état de l'art, dans la mesure du nécessaire;
- certaines modifications, en particulier, ont été apportées aux Articles 15, 22, et 25;
- les marquages et instructions (Article 7) ont été révisés fondamentalement;
- une nouvelle Annexe AA 'Emission de bruit acoustique' a été ajoutée;
- et une nouvelle Annexe BB 'Emission de vibrations' a été ajoutée. Mots clé: machines de nettoyage par pulvérisation et aspiration; agent nettoyant
Cette publication doit être lue conjointement avec la CEI 60335-1:2010.

Part 2-68: Particular requirements for spray
extraction machines, for commercial use
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
