34、rticular 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
35、on all questions concerning standardization in the electrical and electronic elds. To this end and in addition to other activities, IEC publishes International Standards, Technical Specications, Technical Reports, Publicly Available Specications (PAS) and Guides (hereafter referred to as “IEC Public
36、ation(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 nongovernmental organizations liaising with the IEC also participate in this preparation. IEC
37、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 opin
38、ion 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 e
39、nsure 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
40、 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 certicati
41、on 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 certication bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attac
42、h 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)
43、 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
44、. 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 61010-2-011 has been prepared by IEC technical committee 66: S
45、afety of measuring, control and laboratory equipment. It has the status of a group safety publication in accordance with IEC Guide 104.

46、he text of this standard is based on the following documents: FDIS Report on voting 66/589/FDIS 66/598/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/
47、IEC Directives, Part 2. A list of all parts of the IEC 61010 series, under the general title, Safety requirements for electrical equipment for measurement, control, and laboratory use, may be found on the IEC website. IEC 61010-2-011 is to be used in conjunction with the latest edition of IEC 61010-
48、1. It was established on the basis of the third edition (2010) of IEC 61010-1. This Part 2-011 supplements or modies the corresponding clauses in IEC 61010-1 so as to convert that publication into the IEC standard: Particular requirements for REFRIGERATING EQUIPMENT. Where a particular subclause of
49、Part 1 is not mentioned in this Part 2, that subclause applies as far as is reasonable. Where this part states “addition”, “modication”, “replacement”, or “deletion”, the relevant requirement, test specication, or note in Part 1 should be adapted accordingly. In this standard: 1) the following print types are used: requirements and denitions: in roman type; NOTES: in smaller roman type; conformity and tests: in italic type; terms used throughout this standard which have been dened in Clause 3: SMA
