Isolationskoordination für elektrische Betriebsmittel in Niederspannungsanlagen - Teil 3: Anwendung von Beschichtungen, Eingießen oder Vergießen zum Schutz gegen Verschmutzung

Coordination de l'isolement des matériels dans les systèmes (réseaux) à basse tension - Partie 3: Utilisation de revêtement, d'empotage ou de moulage pour la protection contre la pollution

S'applique aux cartes imprimées rigides équipées protégées par un revêtement de matériau isolant déposé sur une de leurs faces ou sur les deux. Décrit les prescriptions et les modes opératoires des essais. A le statut d'une publication fondamentale de sécurité conformément au Guide 104.

Uskladitev izolacije za opremo v okviru nizkonapetostnih sistemov - 3. del: Zaščita pred onesnaženjem s prevlekami, zapiranjem v ohišja ali zalivanjem

Ta del velja za montaže, zaščitene pred onesnaževanjem s prevlekami, zapiranjem v ohišja ali z zalivanjem, kar omogoča zmanjševanje čiščenja in razdalj pri uhajanju, kot je opisano v Delu 1 ali Delu 2. Ta standard opisuje zahteve in preskusne postopke za dve metodi zaščite:  - zaščita tipa 1 izboljšuje mikrookolje zaščitenih delov; zaščita tipa 2 se šteje za podobno trdni izolaciji. Ta standard velja tudi za vse vrste zaščitenih tiskanih plošč, vključno s površino notranjih plasti večplastnih plošč, substratov in podobno zaščitenih montaž, v primeru večplastnih tiskanih plošč pa so razdalje med notranjo plastjo zajete v zahtevah za trdno zaščito v Delu 1. Ta standard se nanaša le na stalno zaščito. Ne zajema montaž, ki so podvržene mehanski prilagoditvi ali popravilu. Načela tega standarda veljajo za funkcionalno, osnovno, nadomestno in okrepljeno izolacijo.

60664-3  IEC:2003– 5 –INTERNATIONAL ELECTROTECHNICAL COMMISSION____________INSULATION COORDINATION FOR EQUIPMENTWITHIN LOW-VOLTAGE SYSTEMS –Part 3: Use of coating, potting or mouldingfor protection against pollutionFOREWORD1)The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between thetwo organizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technical reports or guides and they are accepted by the NationalCommittees in that sense.4)
In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)
The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)
Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 60664-3 has been prepared by IEC technical committee 109:Insulation coordination for low-voltage equipment.This second edition cancels and replaces the first edition, published in 1992, and constitutesa technical revision.It has the status of a basic safety publication in accordance with IEC Guide 104.The text of this standard is based on the following documents:FDISReport on voting109/24/FDIS109/31/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.SIST EN 60664-3:2004

60664-3  IEC:2003– 7 –The major changes made during the revision of IEC 60664-3 were the following:• Part 3 has been exactly aligned with Part 1 (including amendments 1 and 2). It has beenmade clear that Part 3 can only be used as a whole document together with Part 1 ofIEC 60664.• The scope of Part 3 has been greatly extended including now also potting and mouldingand similar procedures providing protection against pollution. The standard also applies toall kinds of coated printed boards including the surface of inner-layers of multi-layerboards, substrates and similar protected assemblies. The distances through an innerlayer of multi-layer boards however are covered by the requirements for solid insulationin Part 1.• The difference between the two types
