The significant changes with respect to EN 60519-6:2002 are as follows: the third edition of EN 60519-1:2003 has been taken into account (the structure of clauses was adapted to it as far as practicable); some defin

13、itions are modified or brought into line with IEC 60050-841:2004; clauses on abnormal operation, access openings, 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 lim

It is intended to specify particular requirements for industrial microwave heating equipment. This Part 6 supplements or modifies the corresponding clauses of EN 60519-1, so as to convert it

15、 into an EN standard. Where a particular sub-clause of Part 1 is not mentioned in this Part 6, that sub-clause 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 Sub-clauses and notes

28、5 INTRODUCTION This edition of IEC 60519-6 contains 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 a

29、nd laboratory microwave appliances. Criteria for discrimination between these categories are dealt with in the scope. BS EN 60519-6:2011 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 i

30、s applicable to equipment using microwave energy alone or in combination 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

31、of the microwave band at 300 GHz is very short and particular leakage 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

32、GHz universally, and between 896 MHz and 918 MHz in some regions. For 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

33、 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). NOTE 2 Since microwave tunnel ovens and also some other types of microwave equipment may be either for commercial, laboratory or industrial use, the

34、following criteria are suitable for determination of the classification 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 proce

35、ssed goods are consumed or ready for final use at the end of the heating 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 o

36、f 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 state from the perspective of the end user. 2 Normative references The following referenced documents are indispensable for the
