Safety requirements for electrical equipment for measurement, control and laboratory use - Part 2-012: Particular requirements for climatic and environmental testing and other temperature conditioning equipment
IEC 61010-2-012:2019 is available as IEC 61010-2-012:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61010-2-012:2019 specifies safety requirements for electrical equipment and its accessories within the categories a) through c), wherever it is intended to be used, whenever that equipment incorporates one or more of the following characteristics: – A refrigerating system that is acted on or impacted by an integral heating function such that the combined heating and refrigerating system generates additional and/or more severe hazards than those for the two systems if treated separately. – The materials being treated in the intended application introduce significant heat into the refrigerating system, so that the refrigerating system in the application yields additional and/or more severe hazards than those for the refrigerating system if operated at the maximum rated ambient temperature alone. – An irradiation function for the materials being treated presenting additional hazards. – A function to expose the materials being treated to excessive humidity, carbon dioxide, salt mist, or other substances which can result in additional hazards. – A function of mechanical movement presenting additional hazards. – Provision for an operator to walk in to the operating area to load or unload the materials being treated. It has the status of a group safety publication in accordance with IEC Guide 104. This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment with changes introduced by Amendment 1 of IEC 61010-1:2010; b) changes related to the use of small capitals for defined terms only; c) clarifications for cooling tests in 4.4.2.10; d) requirements for overtemperature protection in 10.101, including deletion of the second part of the sentence in item b), and the deletion of item c); e) changes pertaining to the accurate employment of terms "temperature", "operating temperature", "working temperature", "application temperature", "room temperature" and "ambient temperature" in 3.5.104, 3.5.105, 4.3.1, 4.3.2, 5.4.2, 8.2.1, 8.2.2, 11.7.2.101.2, 11.7.2.101.3, 13.2.102, 14.102, 15.101, 15.102, 15.103, Introduction and many other locations. For the purpose of clarification, the definition of 3.5.114, controlled temperature, is added.

Varnostne zahteve za električno opremo za meritve, nadzor in laboratorijsko uporabo - 2-012. del: Posebne zahteve za opremo za klimatska in okoljska preskušanja ter drugo opremo za uravnavanje temperature
Ta del standarda IEC 61010 določa varnostne zahteve za električno opremo in njene dodatke v kategorijah od a) do c), kjer koli je namenjena za uporabo in ima eno ali več spodaj navedenih lastnosti:
– HLADILNI SISTEM, ki ga upravlja ali nanj vpliva vgrajena grelna funkcija tako, da skupni grelni in HLADILNI SISTEM ustvarjata dodatne in/ali večje NEVARNOSTI, kot če bi bila sistema neodvisna;
– materiale, ki se obdelujejo pri namenski uporabi, vpeljejo znatno količino toplote v HLADILNI SISTEM, tako da HLADILNI SISTEM pri taki uporabi ustvarja dodatne in/ali večje NEVARNOSTI, kot če bi deloval zgolj pri največji NAZIVNI temperaturi okolja;
– funkcijo obsevanja obdelovanih materialov, ki predstavlja dodatne NEVARNOSTI;
– funkcijo za izpostavljanje materialov, ki se obdelujejo, prekomerni vlagi, ogljikovemu dioksidu, solni megli ali drugim snovem, ki lahko povzročijo dodatne NEVARNOSTI;

SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT
FOR MEASUREMENT, CONTROL, AND LABORATORY USE –
Part 2-012: Particular requirements for climatic and environmental
testing and other temperature conditioning equipment
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
