35、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, Tech
36、nical 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 wor
37、k. 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
38、) 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 recommen
39、dations 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 e
40、nd 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 public
41、ation 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 independ
42、ent 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 per
43、sonal 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 re
44、ferences 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 f
45、or identifying any or all such patent rights. A PAS is an intermediate specification not fulfilling the requirements for a standard, but made available to the public. IEC PAS 63124 has been processed by subcommittee 59D: Performance of household and similar electrical laundry appliances, of IEC tech
46、nical committee 59: Performance of household and similar electrical appliances. The text of this PAS is based on the following document: This PAS was approved for publication by the P-members of the committee concerned as indicated in the following document Draft PAS Report on voting 59D/447/DPAS 59
47、D/451/RVDPAS Following publication of this PAS, which is a pre-standard publication, the technical committee or subcommittee concerned may transform it into an International Standard. IEC PAS 63124:2017 IEC 2017 7 This document is based on CLC/TS 50594:2015. This PAS shall remain valid for an initia
48、l maximum period of 2 years starting from the publication date. The validity may be extended for a single period up to a maximum of 2 years, at the end of which it shall be published as another type of normative document, or shall be withdrawn. IMPORTANT The colour inside logo on the cover page of t
49、his publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 8 IEC PAS 63124:2017 IEC 2017 TUMBLE DRYERS FOR COMMERCIAL USE METHODS FOR MEASURING THE PERFORMANCE 1 Scope This PAS is applicable to tumble dryers for commercial use of the automatic and non- automatic type, incorporating an electric or steam heating device. It also includes tumbl
