31、ir severities Storage 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
32、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 prep
33、aration 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
34、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 s
35、ubjects 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 techni
36、cal 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 exten
37、t 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 c
38、onformity 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 d
39、irectors, 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 ari
40、sing 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
41、 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 condi
42、tions, 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 simplifie
43、d. b) Clause 4: reworded and simplified. c) Clause 5: Annex C has been incorporated in Clause 5. BS EN IEC 60721-3-1:2018 4 IEC 60721-3-1:2018 IEC 2018 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
44、 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 cond
45、itions 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. j) Table 5 new mechanically active substances classes. k) Table 6: new mechanical conditions classes. The text of this International S
46、tandard is based on the following documents: FDIS Report on voting 104/772/FDIS 104/782/RVD Full information on the voting for the approval of this International Standard can be found in the report on voting indicated in the above table. This document has been drafted in accordance with the ISO/IEC
47、Directives, Part 2. A list of all parts in the IEC 60721 series, published under the general title Classification of environmental conditions, can be found on the IEC website. The committee has decided that the contents of this document will remain unchanged until the stability date indicated on the
48、 IEC website under “http:/webstore.iec.ch“ in the data related to the specific document. At this date, the document will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

49、assification of groups of environmental parameters and their severities Storage 1 Scope and object This part of IEC 60721 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
