IEC 61010-2-011:2016

Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-011: Particular requirements for refrigerating equipment

IEC 61010-2-011:2016 specifies particular safety requirements for the following types a) to c) of electrical equipment and their accessories, wherever they are intended to be used, whenever that equipment incorporates REFRIGERATING SYSTEMS whether an integral part of, or remote to the equipment and the equipment is in direct control of the REFRIGERATING SYSTEM. This Part 2 details all the requirements when up to 150 g of FLAMMABLE REFRIGERANT are used per stage of a REFRIGERATING SYSTEM. Additional requirements beyond the current scope of this standard apply if a refrigerant charge of FLAMMABLE REFRIGERANT exceeds this amount. It has the status of a horizontal standard 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 2-011: Exigences particulières pour appareils de réfrigération

L'IEC 61010-2-011:2016 spécifie les exigences de sécurité particulières pour les types a) à c) suivants d'appareils électriques et leurs accessoires, quel que soit l'endroit dans lequel ils sont destinés à être utilisés, lorsque ces appareils comportent des SYSTEMES FRIGORIFIQUES, que ces derniers fassent partie intégrante des appareils ou qu'ils soient distants des appareils, et que les appareils sont sous la commande directe du SYSTEME FRIGORIFIQUE. La présente Partie 2 décrit toutes les exigences correspondant à l'utilisation d'une quantité de FLUIDE FRIGORIGENE INFLAMMABLE allant jusqu'à 150 g par étage d'un SYSTEME FRIGORIFIQUE. Lorsqu'une charge de FLUIDE FRIGORIGENE INFLAMMABLE dépasse cette quantité, des exigences supplémentaires hors du domaine d'application de la présente norme s'appliquent. Elle a le statut de norme horizontale conformément au IEC Guide 104.

SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT

FOR MEASUREMENT, CONTROL, AND LABORATORY USE –

Part 2-011: Particular requirements for REFRIGERATING 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 a
