IEC 61010-2-012:2016

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 61010-2-012:2016 specifies safety requirements for electrical equipment and their accessories within the categories a) through c), wherever they are 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 cooling 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 that the cooling system in the application yield additional and/or more severe HAZARDS than those for the cooling system if operated at the maximum RATED ambient 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 may 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 publication is to be read in conjunction with IEC 61010-1:2010.

Règles de sécurité pour appareils électriques de mesurage, de régulation et de laboratoire - Partie 2-012: Exigences particulières pour appareils d'essais climatiques et d'environnement, et autres appareils de conditionnement de température

L'IEC 61010-2-012:2016 spécifie les exigences de sécurité pour les appareils électriques et leurs accessoires relevant des catégories a) à c) quelle que soit l'utilisation à laquelle ils sont destinés, lorsque ces appareils comprennent une ou plusieurs des caractéristiques suivantes:
- Un SYSTEME FRIGORIFIQUE affecté ou influencé par une fonction de chauffage intégrée de sorte que le système de chauffage et de refroidissement combiné engendre des DANGERS supplémentaires et/ou plus graves que ceux pour les deux systèmes s'ils sont traités séparément.
- Les matières traitées dans l'application prévue génèrent une chaleur importante dans le SYSTEME FRIGORIFIQUE, de sorte que le système de refroidissement dans l'application engendre des DANGERS supplémentaires et/ou plus graves que ceux pour le système de refroidissement dans le cas où il est utilisé seul à la température ambiante ASSIGNEE maximale.
- Une fonction d'exposition aux rayonnements pour les matières traitées qui présentent des DANGERS supplémentaires.
- Une fonction dédiée à l'exposition des matières traitées à une humidité excessive, au dioxyde de carbone, au brouillard salin ou à d'autres substances qui peuvent engendrer des DANGERS supplémentaires.
- Une fonction de MOUVEMENT MECANIQUE qui présente des DANGERS supplémentaires.
- Un dispositif qui permet le déplacement de l'OPERATEUR vers la zone de manoeuvre afin de charger ou décharger les matières traitées.
Elle a le statut d'une publication groupée de sécurité conformément au Guide IEC 104.
Cette publication doit être lue conjointement avec la IEC 61010-1:2010

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
