(Main)Method for the determination of the proof and the comparative tracking indices of solid insulating materials
Method for the determination of the proof and the comparative tracking indices of solid insulating materials
Describes a method of test intended to indicate the relative resistance of solid electrical insulating materials to tracking for voltages up to 600 V when exposed under electric stress to water with the addition of contaminants on the surface. Has the status of a basic safety publication in accordance with IEC Guide 104.
Verfahren zur Bestimmung der Prüfzahl und der Vergleichszahl der Kriechwegbildung von festen, isolierenden Werkstoffen
Méthode de détermination des indices de résistance et de tenue au cheminement des matériaux isolants solides
Donne une indication de la résistance relative au cheminement des isolants électriques solides aux tensions inférieures ou égales à 600 V lorsque leur surface est exposée, sous contrainte électrique, à l'action d'eau contenant des impuretés ioniques. A le statut d'une publication fondamentale de sécurité conformément au Guide 104
Metoda za ugotavljanje preskusnih in primerjalnih indeksov ustvarjanja prevodnih poti trdnih izolacijskih materialov (IEC 60112:2003)
Standard določa preskusno metodo z izmeničnimi napetostmi za ugotavljanje preskusnih in primerjalnih indeksov ustvarjanja prevodnih poti trdnih izolacijskih materialov na kosih, vzetih iz delov opreme, in na ploščah materiala. Standard po potrebi zagotavlja ugotavljanje erozije. Rezultatov preskusa ni mogoče uporabiti neposredno za vrednotenje varnih plazilnih razdalj pri projektiranju električnih naprav. Ima status osnovne varnostne publikacije v skladu z IEC Vodilom 104. Večje spremembe od prejšnje izdaje so naslednje: Izbor materiala za določeno uporabo pogosto vključuje kompromise glede ravni posameznih lastnosti in preskusnih meril. V prejšnji izdaji IEC 60112 so preskusna merila zahtevala, da se »vzorec ne sežiga«, vendar je to izpostavilo dve vprašanji:
– težave pri prepoznavanju gorenja, ki vključuje vse vrste zgorevanja, npr. plamtenje in tlenje, v primeru, da je prišlo do iskrenja, kar je pogosto povzročilo nastanek ogljika na površini vzorca, in
– nekateri odbori za proizvode so v nekaterih primerih ugotovili, da je treba odpraviti merilo »brez sežiganja« pri preskusih ustvarjanja prevodnih poti, in so ga nadomestili s preskusom z gorenjem končnega proizvoda, s čimer sta nastali dve vrsti CTI/PTI z različnimi merili.
