IEC 60068-2-5:2010

Environmental testing - Part 2-5: Tests - Test Sa: Simulated solar radiation at ground level and guidance for solar radiation testing

IEC 60068-2-5:2010 provides guidance for testing equipment or components under solar radiation conditions. The purpose of testing is to investigate to what extent the equipment or components are affected by solar radiation. This second edition cancels and replaces the first edition of IEC 60068-2-5, published in 1975, and IEC 60068-2-9, published in 1975, and constitute a technical revision. The main changes with respect to the previous edition are listed below: This second edition of IEC 60068-2-5 will make the reading much easier, partly because it includes guidance for solar radiation testing, previously published in a separate publication, IEC 60068-2-9, and partly because it now allows the use of all lamps specified in CIE 85 and published in 1985 by the International commission on Illumination. The contents of the corrigendum of December 2010 have been included in this copy.

Essais d'environnement - Partie 2-5: Essais - Essai Sa: Rayonnement solaire simulé au niveau du sol et guide pour les essais de rayonnement solaire

La CEI 60068-2-5:2010 donne des lignes directrices pour l'essai d'équipements ou de composants soumis à des conditions de rayonnement solaire. L'objectif de cet essai est d'étudier dans quelles proportions les équipements ou les composants sont affectés par le rayonnement solaire. Cette deuxième édition annule et remplace la première édition, publiée en 1975. Elle constitue une révision technique. Les modifications principales par rapport à l'édition précédente sont les suivantes: Cette deuxième édition de la CEI 60068-2-5 est beaucoup plus facile à lire en partie grâce à l'intégration des lignes directrices pour l'essai de rayonnement solaire, auparavant publiées dans une norme séparée, CEI 60068-2-9, et en partie par la possibilité d'utiliser désormais toutes les lampes spécifiées dans la CIE 85, publiée en 1985, par la Commission Internationale de l'Eclairage. Le contenu du corrigendum de décembre 2010 a été pris en considération dans cet exemplaire.

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 60068-2-5 has been prepared by IEC technical committee 104:
Environmental conditions, classification and methods of test.
This second edition cancels and replaces the first edition of IEC 60068-2-5, published in
1975, and IEC 60068-2-9, published in 1975, and constitutes a technical revision.
The main changes with respect to the previous edition are listed below:
This second edition of IEC 60068-2-5 will make the reading much easier, partly because it
includes guidance for solar radiation testing, previously published in a separate publication,
IEC 60068-2-9, and partly because it now allows the use of all lamps specified in CIE 85 and
published in 1985 by the International commission on Illumination.
