新的！IEC 60721-3-1:20 18作为IEC 60721-3-1:20 18 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60721-3-1:20 18对产品及其包装（如有）在储存时受到的环境参数组及其严重程度进行了分类。本文件中规定的环境条件仅限于可直接影响产品或其最终性能的环境条件。仅考虑环境条件本身。没有给出这些条件对产品的影响的特殊描述。不包括与火灾或爆炸直接相关的环境条件。固定使用条件、便携式和非固定使用条件、在车辆和船舶上使用条件以及运输条件在IEC 60721-3系列。本第三版取消并取代1997年出版的第二版，构成技术修订。与上一版相比，此版本包括以下重大技术变更:a.第3条:重新措辞和简化。b.第4条:重新措辞和简化。c.第5条:附件C已纳入第5条。d.5.2:所有现有的气候类别都已被全新的类别所取代。新班级被分成3组。新类别的原因是IEC 60721-2-1的最新修订版纳入了新的气候类型。e.5.3:太阳辐射和雪负荷的新等级。f.5.6:机械活性物质的所有现有类别已被全新类别取代。g.5.7:所有现有的机械条件等级已被全新的等级所取代。h.表1:具有新严重性的新气候类别。i.表2:太阳辐射和雪负荷的新等级。j.表5.新的机械活性物质类别。k.表6:新的机械条件等级。

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d. 5.2: all existing climate classes have been replaced by completely new classes.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f. 5.6: all existing classes for mechanically active substances have been replaced by completely new classes.
g. 5.7: all existing classes for mechanical conditions have been replaced by completely new classes.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. 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.
