23、 IEC:2011 3 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ SAFETY IN ELECTROHEAT INSTALLATIONS Part 6: Specifications for safety in industrial microwave heating equipment FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all natio
24、nal 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
25、 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. In
26、ternational, 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
27、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 recommendation
28、s 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 use
29、r. 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
30、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 independent ce
31、rtification 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 personal
32、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 referenc
33、es 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 ide
34、ntifying any or all such patent rights. International Standard IEC 60519-6 has been prepared by IEC technical committee 27: Industrial electroheating. This third edition cancels and replaces the second edition published in 2002 and constitutes a technical revision. The significant changes with respe
35、ct to the previous edition are as follows: the third edition of IEC 60519-1:2003 has been taken into account (the structure of clauses was adapted to it as far as practicable); some definitions are modified or brought into line with IEC 60050-841:2004; clauses on abnormal operation, access openings,
36、 microwave enclosure and barriers are added; the microwave leakage measurements are in a normative Annex A; an informative Annex B on the rationales for microwave exposure and leakage limits is added; Bibliography is added. 4 60519-6 IEC:2011 This part of IEC 60519 is to be used in conjunction with
37、IEC 60519-1:2003. It is intended to specify particular requirements for industrial microwave heating equipment. This Part 6 supplements or modifies the corresponding clauses of IEC 60519-1, so as to convert it into an IEC standard. Where a particular subclause of Part 1 is not mentioned in this Part
38、 6, that subclause applies as far as is reasonable. Where this standard states “addition“, modification“ or “replacement“, the relevant text of Part 1 is to be adapted accordingly. NOTE Subclauses and notes which are additional to those in Part 2 are numbered starting from 101, additional items and
39、annexes are lettered aa, bb or AA, BB, etc. The text of this standard is based on the following documents: CDV Report on voting 27/704/CDV 27/752/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 h
40、as been drafted in accordance with the ISO/IEC Directives, Part 2. The list of all parts of the IEC 60519 series, under the general title Safety in electroheat installations, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until
41、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, withdrawn, replaced by a revised edition, or amended. 60519-6 IEC:2011 5 INTRODUCTION This edition of IEC 60519-6 contain
42、s updates and revisions of IEC 60519-6:2002, which was used over several years. It specifies safety requirements for industrial microwave heating equipment and installations specially designed for specific applications, unlike household, commercial and laboratory microwave appliances. Criteria for d
43、iscrimination between these categories are dealt with in the scope. 6 60519-6 IEC:2011 SAFETY IN ELECTROHEAT INSTALLATIONS Part 6: Specifications for safety in industrial microwave heating equipment 1 Scope This part of IEC 60519 is applicable to equipment using microwave energy alone or in combinat
44、ion with other kinds of energy for industrial heating of materials. This part is applicable to industrial microwave heating equipment operating in the frequency range 300 MHz to 300 GHz. NOTE 1 Since the wavelength of the high end of the microwave band at 300 GHz is very short and particular leakage
45、 measurement instrumentation is needed in the low end of the band, the microwave leakage specification in Annex A applies only for the ISM frequencies between 800 MHz and 6 GHz. The centre frequencies of these are 2,45 GHz and 5,8 GHz universally, and between 896 MHz and 918 MHz in some regions. For
46、 such microwave equipment IEC 62311 applies. For other microwave frequencies, the basic restriction as addressed in informative Annex B or the ICNIRP Guidelines (see Bibliography) may be used. This part does not apply to appliances for household and similar use (covered by IEC 60335-2-25), commercia
47、l use (covered by IEC 60335-2-90) or laboratory use (covered by IEC 61010-2-010). NOTE 2 Since microwave tunnel ovens and also some other types of microwave equipment may be either for commercial, laboratory or industrial use, the following criteria are suitable for determination of the classificati
48、on as industrial equipment: commercial equipment is typically designed and planned for series production of many identical units, whereas industrial equipment is typically produced in small series or even as single units. The processed goods are consumed or ready for final use at the end of the heat
49、ing process. laboratory heating equipment is for preparing material in a laboratory environment, and the processed material is immediately available for investigations or further processing. Regular production of large quantities of material is not foreseen. with industrial equipment, the processed goods are not immediately accessible to the end user, and the goods may additionally not be in a final sta
