INTERNATIONAL ELECTROTECHNICAL COMMISSION
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.
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.
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.
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.
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.
All users should ensure that they have the latest edition of this publication.
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.
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.
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.
International Standard IEC 62885-2 has been prepared by subcommittee 59F: Surface cleaning appliances, of IEC technical committee 59: Performance of household and similar electrical appliances.
This second edition of IEC 62885-2 cancels and replaces the first edition published in 2016. This edition constitutes a technical revision.
This second edition includes the following significant technical changes with respect to the previous edition:
Inclusion of requirements for water filter vacuum cleaners throughout document
Clause 4.6 on operation of the dry vacuum cleaner has been revised.
Add new paragraph 4.11, consolidating test area and stroke length from 5.1.2, 5.3.2,
6.2.2 and 6.16.2.2. Added new 4.12 for stroke speed.
Added debris pick-up test for hard floor and carpet. Includes new Annex E.
Clause 6.2.2 – Clarification of the carpet to be used; reference 4.11 for test area. Remove restriction limiting carpets to motion resistance only. Clarify the use of a mechanical operator.
A durability test for secondary hoses has been included.
The informative annexes relating to the description and maintenance of the reference vacuum cleaner system RSB have been updated.
The text of this standard is based on the following documents:
Draft | Report on voting |
59F/434/FDIS | 59F/438/RVD |
Full information on the voting for its approval can be found in the report on voting indicated in the above table.
The language used for the development of this International Standard is English.
A list of all the parts in the IEC 62885 series, under the general title Surface cleaning appliances, can be found on the IEC website.
In this standard, the following print types are used:
terms defined in Clause 3: bold type.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are described in greater detail at www.iec.ch/standardsdev/publications.
The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the IEC website under webstore.iec.ch in the data related to the specific document. At this date, the document will be
reconfirmed,
withdrawn,
replaced by a revised edition, or
amended.
This part of IEC 62885 is applicable for measurements of the performance of mains-operated
NOTE 1 Measurements of the performance of mains-operated commercial dry vacuum cleaners are found in IEC 62885-8.
The purpose of this document is to specify essential performance characteristics of dry vacuum cleaners which are of interest to users and to describe methods for measuring these characteristics.
NOTE 2 Due to the influence of environmental conditions, variations in time, origin of test materials and proficiency of the operator, some 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.
NOTE 3 The methods here can be applied with modifications for surface-cleaning product types or technologies not currently covered within the scope.
For safety requirements, reference is made to IEC 60335-1.
A recommendation on information for the consumer at the point of sale is given in Annex B.
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
