38 severities – Ground Vehicle Installations
40 FOREWORD
41 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
42 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
43 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
44 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
45 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
46 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
47 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
48 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
49 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
50 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
51 consensus of opinion on the relevant subjects since each technical committee has representation from all
52 interested IEC National Committees.
53 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
54 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
55 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
56 misinterpretation by any end user.
57 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
58 transparently to the maximum extent possible in their national and regional publications. Any divergence between
59 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
60 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
61 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
62 services carried out by independent certification bodies.
63 6) All users should ensure that they have the latest edition of this publication.
64 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
65 members of its technical committees and IEC National Committees for any personal injury, property damage or
66 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
67 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
68 Publications.
69 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
70 indispensable for the correct application of this publication.
71 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
72 rights. IEC shall not be held responsible for identifying any or all such patent rights.
73 International Standard IEC 60721-3-5 has been prepared by IEC technical committee 104:
74 Environmental conditions, classification, and methods of test.
75 This third edition cancels and replaces the second edition, published in 1997, and constitutes
76 a technical revision.
77 This edition includes the following significant changes with respect to the previous edition:
78 a) Most classes have been replaced by completely new classes based on the use of
79 additional information obtained from referenced Technical Reports.
IEC CDV 60721-3-5 © IEC 2024 4 104/1084/CDV
80 b) Table 1 through to Table 7 have been reviewed and updated.
81 c) The content of Annex A and B has either been incorporated into main body text or deleted.
82 The text of this International Standard is based on the following documents:
FDIS Report on voting

84 Full information on the voting for the approval of this International Standard can be found in the
85 report on voting indicated in the above table.
86 This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
87 A list of all parts in the IEC 60721 series, published under the general title Classification of
88 environmental conditions, can be found on the IEC website.
89 The committee has decided that the contents of this document will remain unchanged until the
90 stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
91 the specific document. At this date, the document will be
92 • reconfirmed,
93 • withdrawn,
94 • replaced by a revised edition, or
95 • amended.

98 CLASSIFICATION OF ENVIRONMENTAL CONDITIONS –
99 Part 3-5: Classification of groups of environmental parameters and their
100 severities – Ground Vehicle Installations
101 1 Scope and object
102 This part of IEC 60721 classifies the groups of environmental parameters and their severities
103 to which a product. not forming part of the vehicle, is subjected when installed on or in a ground
104 vehicle. Such products are for example radios, communication systems, fare meters, flow
105 meters for liquids transported by the vehicle, for example milk, petroleum products, etc.
106 Vehicles where products may be permanently or temporarily installed include:
107 • road vehicles: passenger cars, commercial vehicles, special vehicles, towing vehicles,
108 trailers, mopeds, motorcycles,
109 • rail vehicles: trains, trams,
110 • tracked vehicles: excavators, cranes, rubber tracked vehicles,
111 • overland vehicles: four-wheel drive cars, tractors, snow scooters,
112 • handling and storage vehicles: fork-lift trucks (manual and robot), luggage transporters,
113 and
114 • self-propelled machinery: diggers, harvesters.
115 Although this document is not intended for products forming part of the vehicles, the
116 environmental condition classification may also be used for some exchangeable parts, installed
117 in a similar way and in the same locations of the vehicle as products which do not form part of
118 the vehicle. Only severe conditions which may be harmful to products are included.
119 Conditions of storage, transportation and handling are given in IEC 60721-3-1 and
120 IEC 60721-3-2. Classification of storage and transportation environmental conditions are given
121 in other subparts of the IEC 60721-3 series.
122 Accidental incidents are not included but it can be important to take their occurrence into
123 account for products vital to the safety of the ground vehicle.
124 2 Normative references
125 The following documents are referred to in the text in such a way that some or all of their content
126 constitutes requirements of this document. For dated references, only the edition cited applies.
127 For undated references, the latest edition of the referenced document (including any
128 amendments) applies.
