23、CHNICAL COMMISSION _ INDUSTRIAL MICROWAVE HEATING INSTALLATIONS TEST METHODS FOR THE DETERMINATION OF POWER OUTPUT FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committ

24、ees). 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 Availabl

25、e 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 organi

26、zations 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 ma

27、tters 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 Natio

28、nal 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, I

29、EC 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 itse

30、lf 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 t

31、hey 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

32、 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 p

33、ublications 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. International

34、 Standard IEC 61307 has been prepared by IEC technical committee 27: Industrial electroheating. This third edition cancels and replaces the second edition published in 2006. It constitutes a technical revision . This edition includes the following significant technical changes with respect to the pr

35、evious edition:- a) it covers how to measure not only the microwave power output of all typical equipment designs, but also the system efficiency, including the standby and hibernation modes; b) the handling of the former A and B types of equipment is replaced by measurements of the available microw

36、ave power output and microwave workload power, respectively. 4 61307 IEC:2011 The text of this standard is based on the following documents: CDV Report on voting 27/761/CDV 27/782/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in t

37、he above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the s

38、pecific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 61307 IEC:2011 5 INDUSTRIAL MICROWAVE HEATING INSTALLATIONS TEST METHODS FOR THE DETERMINATION OF POWER OUTPUT 1 Scope This International Standard specifies test methods for

39、the determination of the available microwave output power and the efficiency of frequency conversion from the electrical input in industrial microwave heating installations. This standard also specifies test methods for assessing the microwave power deposition in the microwave workload the microwave

40、 workload power, in microwave-only installations. This standard is applicable to industrial microwave heating equipment and installations in the frequency range from 300 MHz to 300 GHz. This standard relates to industrial microwave heating equipment operating under normal load. This standard does no

41、t apply to appliances for household and similar use (covered by IEC 60335-2-25), commercial use (covered by IEC 60335-2-90) or laboratory use (covered by IEC 61010-2-010). 2 Normative references The following referenced documents are indispensable for the application of this document.
