(Main)Electrical insulating materials used under severe ambient conditions - Test methods for evaluating resistance to tracking and erosion
Electrical insulating materials used under severe ambient conditions - Test methods for evaluating resistance to tracking and erosion
This standard describes two test methods for the evaluation of electrical insulating materials for use under severe ambient conditions at power frequencies (45 Hz to 65 Hz) by the evaluation of the resistance to tracking and erosion, using a liquid contaminant and inclined plane specimens. The two methods are: - Method 1: test at constant voltage, - Method 2: test at stepwise increased voltage. Method 1 is the most widely used method as there is less need for continual inspection. The test conditions are designed to accelerate the production of the effects, but do not reproduce all the conditions encountered in service.

Matériaux isolants électriques utilisés dans des conditions ambiantes sévères - Méthodes d'essai pour évaluer la résistance au cheminement et à l'érosion
L'IEC 60587:2022 décrit deux méthodes d'essai pour évaluer les matériaux isolants électriques utilisés dans des conditions ambiantes sévères à des fréquences industrielles (comprises entre 45 Hz et 65 Hz), qui reposent sur l'évaluation de la résistance au cheminement et à l'érosion, à l'aide d'un contaminant liquide et d'éprouvettes plates inclinées. Les deux méthodes sont les suivantes: - Méthode 1: essai à tension constante; - Méthode 2: essai avec augmentation de tension par paliers. La méthode 1 est la plus couramment utilisée, car elle nécessite moins de contrôles en continu. Les conditions d'essai sont conçues pour accélérer la manifestation des effets, mais elles ne reproduisent pas toutes les conditions rencontrées en service. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) une description améliorée des méthodes expérimentales a été établie; b) une description améliorée de la préparation des éprouvettes a été établie; c) une description plus détaillée du matériau et de la qualité des électrodes a été ajoutée; d) le critère d'évaluation B (longueur de la trace de cheminement) a été supprimé pour les essais selon la méthode d'essai 2 (tension de cheminement par paliers), car il ne s'applique pas.
Elektroizolacijski materiali, ki se uporabljajo v težkih okoljskih razmerah - Preskusne metode za ocenjevanje odpornosti proti razenju in eroziji (IEC 60587:2022)
Ta standard opisuje dve preskusni metodi za ocenjevanje električnih izolacijskih materialov za uporabo v težkih okoljskih razmerah pri omrežnih frekvencah (od 45 Hz do 65 Hz) z ocenjevanjem odpornosti proti razenju in eroziji z uporabo tekočega onesnaževalca ter preskušancev z nagnjeno ravnino. Omenjeni metodi sta:
– metoda 1: preskus s konstantno napetostjo;
– metoda 2: preskus s postopnim povečevanjem napetosti.
Najpogosteje se uporablja metoda 1, in sicer zaradi manjše potrebe po stalnem nadzoru.
Preskusni pogoji so zasnovani tako, da pospešijo ustvarjanje učinkov, ne poustvarijo pa vseh pogojev, ki se pojavljajo med uporabo.

ELECTRICAL INSULATING MATERIALS USED
UNDER SEVERE AMBIENT CONDITIONS – TEST METHODS
FOR EVALUATING RESISTANCE TO TRACKING AND EROSION
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 60587 has been prepared by IEC technical committee 112: Evaluation and qualification of
electrical insulating materials and systems. It is an International Standard.
This fourth edition cancels and replaces the third edition published in 2007. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) an improved description of the experimental methods has been
