21、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 Committees). The object of IEC is to promote international co-operation on all quest
22、ions 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(
23、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 coll
24、aborates 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
25、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 ensur
26、e 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
27、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
28、 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 attac
29、h 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)
30、 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
31、. 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 Standard IEC 61307 has been prepared by IEC technical committee 27: Industr
32、ial 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 previous edition:- a) it covers how to measure not only the microwave power ou
33、tput 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 microwave power output and microwave workload power, respectively. 4 61307 IEC:201
34、1 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 the above table. This publication has been drafted in accordance with the ISO
35、/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 specific publication. At this date, the publication will be reconfirmed, with
36、drawn, 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 the determination of the available microwave output power and the efficiency
37、 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 workload power, in microwave-only installations. This standard is applicabl
38、e 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 not apply to appliances for household and similar use (covered by IEC 60335-2-
39、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. For dated references, only the edition cited applies. For undated references, the latest e
