IEC 60212:2010

Standard conditions for use prior to and during the testing of solid electrical insulating materials

IEC 60212:2010 gives the accepted conditions of exposure time, temperature, atmospheric humidity and liquid immersion for use in testing solid electrical insulating materials. The range is sufficiently wide to enable suitable conditions to be selected so that either of the primary objects, set out below as a) and b), of conditioning can be achieved. These objectives aim to obtain greater reproducibility of test results by:
a) partly counteracting the variations of the properties of the material due to the past history of the test specimens (often known as "normalizing", here called preconditioning), and
b) ensuring uniformity of conditions during the testing.
This standard is not intended to be applied for determining the influence of exposure to certain temperatures and humidity or immersions in liquids, on the properties of a material. Procedures pertaining to the effect of an environment on a material are given in various parts of IEC 60068. The significant technical changes with respect to the previous edition are as follows:
- the scope and normative references have been updated and terms and definitions completely reviewed;
- technical details in Table 2 have been aligned to today's usage.

Conditions normales à observer avant et pendant les essais de matériaux isolants électriques solides

La CEI 60212:2010 indique les conditions normales de durée d'exposition, de température, d'humidité atmosphérique et d'immersion dans un liquide à observer pour les essais des matériaux isolants électriques solides. La gamme en est suffisamment étendue pour pouvoir satisfaire aux conditions à déterminer pour atteindre soit l'un soit l'autre des buts premiers du conditionnement (voir a) et b) ci-dessous). Ces objectifs visent à obtenir une reproductibilité plus étendue des résultats d'essai:
a) en neutralisant partiellement les différences constatées sur les propriétés du matériau dues aux influences subies antérieurement par les éprouvettes (traitement souvent connu sous le nom "normalizing" en anglais et appelé ici préconditionnement), et
b) en assurant l'uniformité des conditions au cours des essais.
La présente norme n'est pas destinée à être appliquée pour déterminer l'influence de l'exposition à un certain nombre de températures, de taux d'humidité ou d'immersions dans des liquides, sur les propriétés d'un matériau. Les modalités concernant les effets d'un environnement sur un matériau sont données dans les différentes parties de la CEI 60068. Les modifications techniques majeures par rapport à l'édition précédente sont énumérées comme suit:
- le domaine d'application et les références normatives ont été mises à jour et les termes et définitions complètement revus;
- les détails techniques du Tableau 2 ont été alignés sur l'usage qu'il en est fait de nos jours.

STANDARD CONDITIONS FOR USE PRIOR TO AND DURING
THE TESTING OF SOLID ELECTRICAL INSULATING MATERIALS

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.
International Standard IEC 60212 has been prepared by IEC technical committee 112:
Evaluation and qualification of electrical insulating materials and systems.
This third edition cancels and replaces the second edition published in 1971 and constitutes a
technical revision.
The significant technical changes with respect to the previous edition are as follows:
· the scope and normative references have been updated and terms and definitions
completely reviewed;
· technical details in Table 2 have been aligned to today’s usage.

INTRODUCTION
Many electrical insulating materials have properties which are affected by the temperature or
humidity, or both, of the atmospheres to which they are subjected. It is usually necessary,
therefore, when testing these materials, to control both temperature and humidity prior to
testing, as well as the conditions in which the specimens are actually tested. The selection of
appropriate conditions and tests should be decided according to the materials specification
and the intended application. Unless otherwise specified, specimens should be conditioned
and measured in the same climate as that in which they are to be tested.
When giving results of tests on electrical insulating materials likely to be affected by those
factors, it is important that the relevant conditions to which the test specimens were exposed
are reported. Specifications for such materials should, therefore, identify the atmospheres to
which the test specimens should be exposed before testing and the conditions under which
the tests are to be made.

STANDARD CONDITIONS FOR USE PRIOR TO AND DURING
THE TESTING OF SOLID ELECTRICAL INSULATING MATERIALS

1 Scope
This International Standard gives the accepted conditions of exposure time, temperature,
atmospheric humidity and liquid immersion for use in testing solid electrical insulating
materials. The range is sufficiently wide to enable suitable conditions to be selected so that
either of the primary objects, set out below as a) and b), of conditioning can be achieved.
These objectives aim to obtain greater reproducibility of test results by:
a) partly counteracting the variations of the properties of the material due to the past history
of the test specimens (often known as "normalizing", here called preconditioning), and
b) ensuring uniformity of conditions during the testing.
This standard is not intended to be applied for determining the influence of exposure to
certain temperatures and humidity or immersions in liquids, on the properties of a material.
Procedures pertaining to the effect of an environment on a material are given in various parts
of IEC 60068.
