62 FOREWORD
63 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
64 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
65 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
66 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
67 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
68 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
69 in the subject dealt with may participate in this preparatory work. International, governmental and non -
70 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
71 with the International Organization for Standardization (ISO) in accordance with conditions determined by
72 agreement between the two organizations.
73 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
74 consensus of opinion on the relevant subjects since each technical committee has representation from all
75 interested IEC National Committees.
76 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
77 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
78 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
79 misinterpretation by any end user.
80 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
81 transparently to the maximum extent possible in their national and regional publications. Any divergence
82 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
83 the latter.
84 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
85 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
86 services carried out by independent certification bodies.
87 6) All users should ensure that they have the latest edition of this publication.
88 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
89 members of its technical committees and IEC National Committees for any personal injury, property damage or
90 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
91 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
92 Publications.
93 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
94 indispensable for the correct application of this publication.
95 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
96 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
97 International Standard IEC 60068-3-6 has been prepared by IEC technical committee 104:
98 Environmental conditions, classification and methods of test.
99 This third edition cancels and replaces the second edition published in 2018. This edition
100 constitutes a technical revision.
101 This edition includes the following significant technical changes with respect to the previous
102 edition:
103 a) The contents of IEC 60068-3-5 and IEC 60068-3-6 are merged into this document due to
104 the significant overlap between the two.
105 b) Addition of new terms and definitions for temperature and humidity uniformity.
106 c) Significant editorial re-writing for clarity.
107 d) Clarification of mandatory versus non-mandatory information.
108 e) Updates to several figures.

109 f) New information in bibliography and removal of listings from the normative references
110 section deemed non-mandatory in new edition.
111 The text of this International Standard is based on the following documents:
FDIS Report on voting
104/XXX/XXX 104/XXX/XXX
113 Full information on the voting for the approval of this International Standard can be found in
114 the report on voting indicated in the above table.
115 The French version of this standard has not been voted upon.
116 This document has been drafted in accordance with the ISO/IEC Directives, Part 2. Upon
117 publication, the intention of TC104 is to withdraw IEC 60068-3-5.
118 IEC 60068-3-6 is to be read in conjunction with IEC 60068-3-11:XXXX. A list of all parts in the
119 IEC 60068 series, published under the general title Environmental testing, can be found on
120 the IEC website.
121 The committee has decided that the contents of this document will remain unchanged until the
122 stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
123 the specific document. At this date, the document will be
124 • reconfirmed,
125 • withdrawn,
126 • replaced by a revised
