This International Standard covers electrical mobile motor-operated vacuum cleaners
Equipment Protection Level (EPL) Dc.
This includes dust extractors, for wet suction or dry suction, intended for commercial indoor
use with or without attachments, to collect combustible dust in an explosive dust atmosphere.
The requirements for the construction and testing covered by this document are applied in
addition to the requirements for commercial and industrial vacuum cleaners in
IEC 60335-2-69.
This document supplements and modifies the requirements of IEC 60079-0. Whenever a
requirement of this standard is in conflict with a requirement of IEC 60079-0 the requirement
of this standard will take precedence.
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.
This document does not cover specific hazards associated with extreme ambient
temperatures (less than –20 °C or higher than 40 °C) unless otherwise marked by the
manufacturer as given in IEC 60079-0. The temperatures shall not exceed the temperature
range of –20 °C to +60 °C.
This document does not cover motorized cleaning heads for which additional requirements
are under consideration.
This document does not apply to
– back-pack vacuum cleaners;
– vacuum cleaners with a traction drive;
– vacuum cleaners and water-suction cleaning appliances for household use
(IEC 60335-2-2);
– floor treatment machines for commercial use (IEC 60335-2-67, IEC 60335-2-72);
– spray extraction machines for commercial use (IEC 60335-2-68);

VACUUM CLEANERS AND DUST EXTRACTORS PROVIDING
EQUIPMENT PROTECTION LEVEL Dc FOR THE COLLECTION
OF COMBUSTIBLE DUSTS – PARTICULAR REQUIREMENTS

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 elemen
