EN IEC 60519-6:2024

Safety in installations for electroheating and electromagnetic processing - Part 6: Particular requirements for high frequency dielectric and microwave heating and processing equipment

This part of IEC 60519 is applicable to equipment using high frequency or microwave energy alone or in combination with other kinds of energy for industrial heating and processing of materials. It is also applicable to HF and MW generators made available to users as separate units. This part is applicable to equipment operating in the frequency range 3 MHz to 300 GHz, with the following limitations. - This document applies to only high frequency dielectric heating and processing as defined in 3.1.103. It does not apply to induction heating, which it is possible to carry out in the lower part of the specified frequency band and is covered by IEC 60519-3, with magnetic field safety aspects addressed in IEC TS 62997:2017, the latter to be replaced by a technical report (TR) or by a revised technical specification (TS). - The ISM centre frequencies for dielectric heating and processing of industrial interest are narrow bands about 6,78 MHz, 13,56 MHz, 27,12 MHz and 40,68 MHz. Different field emission measurement procedures and limiting values are applicable, depending on the processing frequency in the high frequency range 3 to 300 MHz. Specifications are in Annex BB. - This document specifies limits for microwave emission only for the ISM frequencies between 800 MHz and 6 MHz, as specified in Annex CC. For other microwave frequencies the basic restriction and IEC 62311 apply. - The foundations for compliance with emission values are the basic restrictions, referred to in the IEEE/ANSI C95.1:2019 and Directive 2013/35/EU. However, maximum HF processing frequency electric and magnetic field values are taken from the IEEE/ANSI C95.1:2019 standard, as indicated in Annex BB. - This document is not applicable to: -- appliances for household and similar use (covered by e.g. IEC 60335-2-25); -- commercial use (covered by IEC 60335-2-90 and IEC 60335-2-110); -- laboratory use (covered by IEC 61010-2-010); -- medical high frequency equipment and accessories (covered by IEC 60601-2-2). NOTE 101 Since high frequency and microwave tunnel ovens and also some other types of microwave and high frequency equipment are sometimes intended either for commercial, laboratory or industrial use, the 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 processed 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 of material is not foreseen. - with industrial equipment, the processed goods are not immediately accessible to the end user, and the goods are sometimes not in a final state from the perspective of the end user.

Sicherheit in Elektrowärmeanlagen und Anlagen für elektromagnetische Bearbeitungsprozesse - Teil 6: Besondere Anforderungen für kapazitive Hochfrequenz- und Mikrowellen-Erwärmungs- und Bearbeitungseinrichtungen

Sécurité dans les installations destinées au traitement électrothermique et électromagnétique - Partie 6: Exigences particulières pour les équipements de chauffage et de traitement diélectriques à hautes fréquences et à hyperfréquences

La CEI 60519-6:2011 est applicable aux installations qui utilisent l'énergie à hyperfréquences, seule ou en combinaison avec d'autres formes d'énergie pour le chauffage industriel des matériaux. La présente partie est applicable aux installations électrothermiques industrielles fonctionnant dans la plage de fréquences comprises entre 300 MHz et 300 GHz. Cette troisième édition annule et remplace la deuxième édition parue en 2002, dont elle constitue une révision technique. Les modifications techniques significatives par rapport à l'édition précédente sont les suivantes: - la troisième édition de la CEI 60519-1:2003 a été prise en compte (la structure des articles a été adaptée à celle-ci dans la mesure du possible); - certaines définitions ont été modifiées ou alignées avec la CEI 60050-841:2004; - des articles concernant un fonctionnement anormal, les ouvertures d'accès, l'enceinte hyperfréquences et les barrages ont été ajoutés; - les mesures de la fuite d'hyperfréquences se trouvent dans une Annexe normative A; - une Annexe informative B concernant les justifications des limites d'exposition aux hyperfréquences et des fuites d'hyperfréquences a été ajoutée; - une bibliographie a été ajoutée.

Varnost pri električnih grelnih inštalacijah in elektromagnetni obdelavi - 6. del: Posebne zahteve za visokofrekvenčno dielektrično in mikrovalovno segrevanje in procesno opremo (IEC 60519-6:2022)

Ta del standarda IEC 60519 se uporablja za opremo, ki uporablja visokofrekvenčno ali mikrovalovno energijo samostojno ali v kombinaciji z drugimi vrstami energije za industrijsko ogrevanje in obdelavo materialov. Uporablja se tudi za visokofrekvenčne (HF) in mikrovalovne (MW) generatorje, ki so uporabnikom na voljo kot ločene enote.
Ta del se uporablja za opremo, ki deluje v frekvenčnem območju od 3 MHz do 300 GHz, pri čemer veljajo naslednje omejitve.
– Ta standard se uporablja samo za visokofrekvenčno dielektrično segrevanje in obdelavo, kot je opredeljeno v točki 3.1.103. Ne uporablja se za indukcijsko segrevanje, ki se lahko izvaja v spodnjem delu navedenega frekvenčnega pasu in je zajeto v standardu IEC 60519-3, pri čemer so varnostni vidiki magnetnega polja obravnavani v standardu IEC TS 62997:2017.
– Srednje frekvence za dielektrično segrevanje in obdelavo v industriji so v nizkem pasu, približno 6,78 MHz, 13,56 MHz, 27,12 MHz in 40,68 MHz. Glede na frekvenco obdelave v visokofrekvenčnem območju od 3 do 300 MHz se uporabljajo različni postopki merjenja emisij polja in različne mejne vrednosti. Specifikacije so podane v dodatku BB.
– Ker je valovna dolžina zgornjega konca mikrovalovnega pasu pri 300 GHz zelo kratka in je za merjenje uhajanja v spodnjem koncu pasu potrebna posebna merilna oprema, se specifikacija mikrovalovnega sevanja v dodatku CC uporablja samo za frekvence ISM med 800 MHz in 6 GHz. Srednje frekvence v okviru teh znašajo univerzalno 2,45 GHz in 5,8 GHz ter med 896 MHz in 918 MHz v nekaterih regijah. Za druge mikrovalovne frekvence se uporablja standard IEC 62311:2019.
– Osnova za skladnost z emisijskimi vrednostmi so osnovne omejitve, navedene v bibliografiji. Največje vrednosti električnega in magnetnega polja pri visokofrekvenčni obdelavi so vzete iz standarda IEEE/ANSI C95.1-2019, kot je navedeno v dodatku BB.
– Ta standard se ne uporablja za:
– aparate za gospodinjsko in podobno uporabo (zajeto v standardu IEC 60335-2-25:2020);
– komercialno uporabo (zajeto v standardih IEC 60335-2-90:2015+AMD1:2019 in IEC 60335-2-110:2013+AMD1:2019);
– laboratorijsko uporabo (zajeto v standardu IEC 61010-2-010:2019);
– visokofrekvenčno medicinsko opremo in pripomočke (zajeto v standardu IEC 60601-2-2:2017);
OPOMBA 101: Visokofrekvenčne in mikrovalovne tunelne pečice ter nekatere druge vrste mikrovalovne in visokofrekvenčne opreme so lahko namenjene za komercialno, laboratorijsko ali industrijsko uporabo, zato so naslednja merila primerna za klasifikacijo kot industrijska oprema:
– komercialna oprema je običajno zasnovana in načrtovana za serijsko proizvodnjo več enakih enot, industrijska oprema pa se običajno proizvaja v majhnih serijah ali celo kot posamezne enote. Obdelano blago se porabi ali je pripravljeno za končno uporabo na koncu procesa segrevanja.
– laboratorijska oprema za segrevanje je namenjena pripravi materiala v laboratorijskem okolju, obdelan material pa je takoj na voljo za preiskave ali nadaljnjo obdelavo. Redna proizvodnja večjih količin materiala ni predvidena.
– pri uporabi industrijske opreme obdelano blago ni takoj dostopno končnemu uporabniku, poleg tega blago z vidika končnega uporabnika morda ni v končnem stanju.
