Passive filter units for electromagnetic interference suppression - Part 2: Sectional specification: Passive filter units for which safety tests are appropriate - Test methods and general requirements

applies to passive filter units for electromagnetic interference suppression which fall within the scope of the Generic Specification EN 60939-1. The scope of this Sectional specification is restricted to passive filter units for which safety tests are appropriate. This implies that filters specified according to this Sectional specification will either be connected to mains supplies, when compliance with the mandatory tests of Table 3 is necessary, or used in other circuit positions where the equipment specification prescribes that some or all of these safety tests are required.

Filtres passifs d'antiparasitage - Partie 2: Spécification intermédiaire: Filtres passifs pour lesquels des essais de sécurité sont appropriés - Méthodes d'essai et règles générales

L'IEC 60939-2:2005 s’applique aux filtres passifs d’antiparasitage qui entrent dans le domaine d’application de la spécification générique IEC 60939-1. Le domaine d’application de la présente spécification intermédiaire est restreint aux filtres passifs pour lesquels des essais de sécurité sont appropriés. Par conséquent, les filtres spécifiés selon la présente spécification intermédiaire sont connectés aux réseaux d’alimentation, lorsque la conformité aux essais obligatoires présentés dans le Tableau 3 est nécessaire, ou sont utilisés dans d’autres endroits du circuit pour lesquels la spécification de l’équipement prescrit que tout ou partie de ces essais de sécurité est exigé. La présente spécification intermédiaire s’applique aux filtres passifs connectés à un réseau d’alimentation en courant alternatif ou à une autre alimentation dont la tension nominale ne dépasse pas 1 000 V en courant alternatif, et dont la fréquence nominale ne dépasse pas 400 Hz ou 1 000 V en courant continu. Les principales modifications effectuées entre la première et la seconde édition comprennent: – Les mesurages de la capacité et de la tangente de l’angle de perte (tan δ), la résistance de ligne continue ou la chute de tension continue au courant assigné, la tension de choc, l’inflammabilité passive, la surcharge de courant, la résistance du marquage au solvant, la résistance des composants au solvant et l’inflammabilité active ont été ajoutés à l’Article 4, procédures d’essai et de mesure. Le contenu du corrigendum de novembre 2005 a été inclus dans la présente copie.

Pasivni filtri za dušenje elektromagnetnega motenja – 2. del: Področna specifikacija: Pasivni filtri, za katere varnostni preskusi ustrezajo – Preskusne metode in splošne zahteve (IEC 60939-2:2005)

Standard se uporablja za pasivne filtre za dušenje elektromagnetnega motenja, ki spadajo v področje uporabe splošnih specifikacij standarda EN 60939-1. Področje uporabe te področne specifikacije je omejeno na pasivne filtre, za katere so ustrezni varnostni preskusi. To pomeni, da se filtri, določeni v skladu s to področno specifikacijo, priključijo na omrežno napajanje, kadar je zahtevana skladnost z obveznimi preskusi iz preglednice 3, ali se uporabijo na drugih mestih v tokokrogu, za katera specifikacija opreme predpisuje, da so zahtevani nekateri ali vsi ti varnostni preskusi.
