EN 60243-1:2013

Electric strength of insulating materials - Test methods - Part 1: Tests at power frequencies

IEC 60243-1:2013 provides test methods for the determination of short-time electric strength of solid insulating materials at power frequencies between 48 Hz and 62 Hz. This standard does not cover the testing of liquids and gases, although these are specified and used as impregnates or surrounding media for the solid insulating materials being tested. NOTE: Methods for the determination of breakdown voltages along the surfaces of solid insulating materials are included.

Elektrische Durchschlagfestigkeit von isolierenden Werkstoffen - Prüfverfahren - Teil 1: Prüfungen bei technischen Frequenzen

Rigidité diélectrique des matériaux isolants - Méthodes d'essai - Partie 1: Essais aux fréquences industrielles

La CEI 60243-1:2013 fournit les méthodes d'essai pour la détermination de la rigidité diélectrique de courte durée des matériaux isolants solides, aux fréquences industrielles comprises entre 48 Hz et 62 Hz. La présente norme ne couvre pas la manière d'effectuer l'essai des liquides ou des gaz bien que ceux-ci soient spécifiés et utilisés comme imprégnants ou comme milieu ambiant pour l'essai des matériaux isolants solides. NOTE: Les méthodes pour déterminer les tensions de claquage en surface des matériaux isolants solides sont indiquées.

Električna prebojna trdnost izolacijskih materialov - 1. del: Preskušanje pri omrežnih frekvencah

Ta del standarda IEC 60243 podaja preskusne metode za določitev kratkoročne električne moči trdnih izolacijskih materialov pri obratovalnih frekvencah med 48 Hz in 62 Hz. Ta standard ne zajema preskušanja tekočin in plinov, čeprav so ti določeni in se uporabljajo kot sredstva za impregnacijo ali sredstva okrog trdnih izolacijskih materialov, ki se preskušajo. OPOMBA Metode za določitev prebojnih napetosti na površinah trdnih izolacijskih materialov so vključene.

This European Standard was approved by CENELEC on 2013-04-30. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the CEN-CENELEC Management Centre or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the CEN-CENELEC Management Centre has the same status as the official versions.
