Classification of environmental conditions - Part 3-1: Classification of groups of environmental parameters and their severities - Storage

NEW!IEC 60721-3-1:2018 is available as IEC 60721-3-1:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60721-3-1:2018 classifies the groups of environmental parameters and their severities to which products together with their packaging, if any, are subjected when stored. The environmental conditions specified in this document are limited to those which can directly affect the products or their ultimate performance. Only environmental conditions as such are considered. No special description of the effects of these conditions on the products is given. Environmental conditions directly related to fire or explosions are not included. Conditions of stationary use, portable and non-stationary use, use in vehicles and ships, and conditions of transportation are given in other subparts of the IEC 60721-3 series. This third edition cancels and replaces the second edition, published in 1997, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a. Clause 3: reworded and simplified. b. Clause 4: reworded and simplified. c. Clause 5: Annex C has been incorporated in Clause 5. d. 5.2: all existing climate classes have been replaced by completely new classes. The new classes are divided into 3 groups. The reason for the new classes is the latest revision of IEC 60721-2-1 which incorporated new climate types. e. 5.3: new classes for solar radiation and snow load. f. 5.6: all existing classes for mechanically active substances have been replaced by completely new classes. g. 5.7: all existing classes for mechanical conditions have been replaced by completely new classes. h.

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 60721-3-1 has been prepared by IEC technical committee 104:
Environmental conditions, classification, and methods of test.
This third edition cancels and replaces the second edition, published in 1997, and constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Clause 3: reworded and simplified.
b) Clause 4: reworded and simplified.

classes are divided into 3 groups. The reason for the new classes is the latest revision of
IEC 60721-2-1 which incorporated new climate types.
e) 5.3: new classes for solar radiation and snow load.
f) 5.6: all existing classes for mechanically active substances have been replaced by
completely new classes.
g) 5.7: all existing classes for mechanical conditions have been replaced by completely new
classes.
h) Table 1: new climatic classes with new severities.
i) Table 2: new classes for solar radiation and snow load.
