Passive filter units for electromagnetic interference suppression - Part 3: Passive filter units for which safety tests are appropriate
IEC 60939-3:2024 is available as IEC 60939-3:2024 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60939-3:2024 covers passive filters used to attenuate unwanted radio-frequency signals (such as noise or interference) generated from electromagnetic sources. Both single and multi-channel filters within one enclosure or which are built on a printed circuit board forming a compact entity are included within the scope of this document. This document applies to passive filter units for electromagnetic interference suppression for which safety tests are appropriate. This implies that filters specified according to this document will either be connected to mains supplies, when compliance with the mandatory tests of Table B.1 is necessary, or used in other circuit positions where the equipment specification specifies that some or all of these safety tests are required. This document applies to passive filter units, which will be connected to an AC mains or other supply (DC or AC) with a nominal voltage not exceeding 1 000 V AC, with a nominal frequency not exceeding 400 Hz, or 1 500 V DC. Note: For AC use, IEC 60384-14 applies to capacitors which will be connected to AC mains with a nominal frequency not exceeding 100 Hz. This document covers appliance filters (US) but does not cover facility filters, cord-connected filters or direct plug-in filters. These other filters will be covered by another sectional specification. This edition includes the following significant technical changes with respect to the previous edition: a) separated clauses for safety and performance tests; b) added note for use of multiple X capacitors bridging basic insulation in 3 phase filters; c) characteristics and conditions to substitute X and Y capacitors are now described in a separate Subclause 4.1; d) creepage and clearance tables updated and in line with the latest editions of IEC 60938-2 and IEC 60664-1; e) allowing voltage measurement for inductance measurements (7.3); f) added requirements for marking depending on remaining energy after disconnection; g) added content of CTL DSH 2044:2016 for temperature test of IEC filters; h) added note about temperature rise required specimens for safety testing; i) changed index of capacitors in Annex A to avoid confusion between index name and capacitor class; j) moved tests from group 1A to 2. Now, samples in group 1A need to be submitted without potting; k) revision of all parts of the document has taken place based on the ISO/IEC Directives, Part 2:2021, and harmonization with other similar kinds of documents. Annex X contains all cross-references of changes in clause/subclause numbers.

Filtres passifs d'antiparasitage - Partie 3: Filtres passifs pour lesquels des essais de sécurité sont appropriés
IEC 60939-3:2024 est disponible sous forme de IEC 60939-3:2024 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L’IEC 60939-3:2024 couvre les filtres passifs utilisés pour atténuer les signaux aux fréquences radioélectriques indésirables (par exemple, le bruit ou le brouillage) générés par des sources électromagnétiques. Les filtres à voie unique et à voies multiples à l’intérieur d’une enveloppe, ou montés sur une carte de circuit imprimé qui forme une entité compacte, font partie du domaine d’application du présent document. Les filtres constitués d’éléments capacitifs dans lesquels l’inductance est inhérente à la construction du filtre font partie du domaine d’application du présent document. De même, les filtres constitués d’éléments inductifs dans lesquels la capacité est inhérente à la construction du filtre font également partie du domaine d’application du présent document. Il appartient au fabricant d’indiquer si un composant donné doit être conçu comme un condensateur, une inductance ou un filtre. Les filtres peuvent également inclure d’autres composants tels que des résistances et/ou des varistances ou des composants similaires. Le présent document s’applique aux filtres passifs d’antiparasitage pour lesquels des essais de sécurité sont appropriés. Ceci implique que les filtres spécifiés selon le présent document sont soit connectés à des réseaux d’alimentation (lorsque la conformité aux essais obligatoires du Tableau B.1 est nécessaire), soit utilisés dans d’autres positions de circuit dans lesquelles la spécification de l’équipement précise que certains ou tous ces essais de sécurité sont exigés. Le présent document s’applique à des filtres passifs qui sont connectés à un réseau d’alimentation en courant alternatif ou à une autre alimentation (en courant continu ou en courant alternatif) dont la tension nominale ne dépasse pas 1 000 V en courant alternatif et dont la fréquence nominale ne dépasse pas 400 Hz, ou dont la tension nominale ne dépasse pas 1 500 V en courant continu. NOTE Pour les applications en courant alternatif, l’IEC 60384-14 s’applique aux condensateurs qui sont connectés au réseau d’alimentation en courant alternatif dont la fréquence nominale ne dépasse pas 100 Hz. Le présent document couvre les filtres d’appareil, mais ne couvre pas les filtres d’installation, les filtres connectés par cordon, ni les filtres enfichables directement. Ces autres filtres seront couverts par une autre spécification intermédiaire. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente: a) des articles ont été séparés pour les essais de sécurité et de performances; b) une note est ajoutée en ce qui concerne l’utilisation de plusieurs condensateurs de classe X qui relient en pont une isolation principale dans les filtres triphasés; c) des caractéristiques et conditions de remplacement des condensateurs de classe X et de classe Y sont maintenant décrites dans un paragraphe 4.1 différent; d) des tableaux de lignes de fuite et de distances d’isolement sont mis à jour et sont conformes aux dernières éditions de l’IEC 60938-2 et de l’IEC 60664-1; e) le mesurage de la tension pour les mesurages de l’inductance est admis (7.3); f) des exigences sont ajoutées pour le marquage selon l’énergie restante après la déconnexion; g) le contenu de CTL DSH 2044:2016 est ajouté pour l’essai de température des filtres IEC; h) une
Pasivni filtri za dušenje elektromagnetnega motenja - 3. del: Enote pasivnih filtrov, za katere varnostni preskusi ustrezajo (IEC 60939-3:2024)
Ta del standarda IEC 60939 zajema pasivne filtre za slabenje neželenih radiofrekvenčnih signalov (kot so šum ali motnje), ki jih ustvarijo elektromagnetni viri.
Ta dokument obravnava tako enokanalne kot tudi večkanalne filtre v enem ohišju ali filtre, nameščene na tiskanem vezju, ki tvorijo kompaktno entiteto.
Področje uporabe tega dokumenta zajema filtre, izdelane iz kapacitivnih elementov, pri katerih zgradba filtra zagotavlja induktivnost. Zajeti so tudi filtri, izdelani iz induktivnih elementov, pri katerih zgradba filtra zagotavlja kapacitivnost. Proizvajalec se sam odloči, ali želi dano komponento označiti kot kondenzator, induktor ali filter. V filtre je mogoče vključiti tudi druge komponente, kot so upori in/ali varistorji ali podobne komponente.
Ta dokument se uporablja za enote pasivnih filtrov za dušenje elektromagnetnega motenja, za katere varnostni preskusi ustrezajo. To pomeni, da se filtri, določeni v skladu s tem dokumentom, priključijo na omrežno napajanje, kadar je zahtevana skladnost z obveznimi preskusi iz preglednice B.1, ali se uporabijo na drugih mestih v tokokrogu, za katera je v specifikaciji opreme določeno, da so zahtevani nekateri ali vsi ti varnostni preskusi.
Ta dokument se uporablja za enote pasivnih filtrov, ki bodo priključene v izmenično napajalno omrežje ali drug vir napajanja (enosmerni ali izmenični) z nazivno izmenično napetostjo do 1000 V z nazivno frekvenco največ 400 Hz oziroma z enosmerno napetostjo 1500 V.
OPOMBA: Pri uporabi z izmenično napetostjo se standard IEC 60384-14 uporablja za kondenzatorje, ki se priključijo na izmenično omrežno napajanje z nazivno frekvenco največ 100 Hz.
Ta dokument zajema filtre za naprave (US), vendar ne zajema filtrov za sisteme, filtrov, priključenih s kablom, ali filtrov za neposredno priključitev. Ti filtri bodo obravnavani v drugi področni specifikaciji.
