Classification of environmental conditions - Part 2-1: Environmental conditions appearing in nature - Temperature and Humidity
IEC 60721-2-1:2013 presents classifications of open-air climates in terms of temperature and humidity. It is intended to be used as part of the background material when selecting appropriate temperature and humidity severities for product testing and application. This second edition cancels and replaces the first edition, published in 1982, and constitutes a technical revision. The main changes with respect to the previous edition are in the definitions of climate types.
Klassifizierung von Umgebungsbedingungen - Teil 2-1: Natürliche Umgebungsbedingungen - Temperatur und Luftfeuchte
Classification des conditions d'environnement - Partie 2-1: Conditions d'environnement présentes dans la nature - Température et humidité
La CEI 60721-2-1:2013 présente des classifications de climats à l'air libre d'après la température et l'humidité. Elle est destinée à fournir une partie des informations de base dont on a besoin pour choisir les sévérités appropriées de température et d'humidité en vue d'essais de produits et de leur application. Cette deuxième édition annule et remplace la première édition, publiée en 1982, et constitue une révision technique. Les modifications principales par rapport à l'édition précédente figurent dans les définitions des types de climat des types de climats.
Klasifikacija okoljskih pogojev - 2-1. del: Okoljski pogoji v naravi - Temperatura in vlaga (IEC 60721-2-1:2013)
Ta del standarda IEC 60721 vključuje klasifikacijo okoljskih pogojev na podlagi temperature in vlage. Namenjen je za uporabo kot del osnovnega gradiva pri izbiri ustreznih ravni temperature in vlage za preskušanje ter uporabo proizvodov. Okoljski pogoji vključujejo vsa območja sveta, razen osrednje Antarktike in območja z visoko nadmorsko višino (nad 5000 m).
Ta klasifikacija se lahko uporablja kot dodatno gradivo pri izdaji podnebnih okoljskih razredov za uporabo proizvodov.
Ta standard določa omejeno število klasifikacij okoljskih pogojev na podlagi temperature in vlage, ki določajo pogoje, ki jih proizvodi najpogosteje izpolnjujejo pri prevozu, skladiščenju, namestitvi ter uporabi.

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 60721-2-1 has been prepared by IEC technical committee 104:
Environmental conditions, classification and methods of test.
This second edition cancels and replaces the first edition published in 1982 and its
amendment 1 (1987), and constitutes a technical revision.
The main changes with respect to the previous edition are in the definitions of climate types.

environmental conditions, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
