VACUUM CLEANERS FOR COMMERCIAL USE –
METHODS FOR MEASURING 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
IEC-PAS 62611 has been processed by subcommittee 59F: Floor treatment appliances, of
IEC technical committee 59: Performance of household and similar electrical appliances.

Following publication of this PAS, which is a pre-standard publication, the technical committee
or subcommittee concerned may transform it into an International Standard.

publication date. The validity may be extended for a single 3-year period, following which it
shall be revised to become another type of normative document, or shall be withdrawn.

INTRODUCTION
This PAS specifies provisional methods of measuring the performance of commercial vacuum
cleaners for use in offices, shops and similar commercial establishments taking into account
the differences in operation compared to household vacuum cleaners.
It is the intention of subcommittee SC 59F to review this PAS based on experience achieved
and publish an International Standard on this subject.

VACUUM CLEANERS FOR COMMERCIAL USE –
METHODS FOR MEASURING PERFORMANCE
1 Scope
These test methods are applicable to vacuum cleaners for commercial use.
The purpose of this PAS is to specify essential performance characteristics of vacuum
cleaners being of interest to the users and to describe methods for measuring these
characteristics.
NOTE Due to the influence of environmental conditions, variations in time, origin of test materials and proficiency
of the operator, most of the described test methods will give more reliable results when applied for comparative
testing of a number of appliances at the same time, in the same laboratory and by the same operator.
For safety requirements, refer to IEC 60335-1, IEC 60335-2-2 and IEC 60335-2-69.
