25、n 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 pu

26、blishes 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 ma

27、y 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 agree

28、ment 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 P

29、ublications 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

30、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 corr

31、esponding 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

32、 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 an

33、d 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) A

34、ttention 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

35、. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61326-1 has been prepared by subcommittee 65A: System aspects, of IEC technical committee 65: Industrial-process measurement, control and automation. This second edition cancels and replaces

36、 the first edition, published in 2005. This edition constitutes a technical revision. The significant technical changes with respect to the previous edition are as follows: the immunity test levels and performance criteria have been reviewed; requirements for portable test and measurement equipment

37、have been clarified and amended; the description of the electromagnetic environments has been improved. 61326-1 IEC:2012 5 The text of this standard is based on the following documents: FDIS Report on voting 65A/628/FDIS 65A/637/RVD Full information on the voting for the approval of this standard ca

38、n be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 61326 series under the general title Electrical equipment for measurement, control and laboratory use EMC requirements,

39、 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 reconfir

40、med, withdrawn, replaced by a revised edition, or amended. 6 61326-1 IEC:2012 INTRODUCTION Instruments and equipment within the scope of this standard may often be geographically widespread and hence operate under a wide range of environmental conditions. The limitation of undesired electromagnetic

41、emissions ensures that no other equipment, installed nearby, is unduly influenced by the equipment under consideration. The limits are more or less specified by, and therefore taken from, IEC and International Special Committee on Radio Interference (CISPR) publications. However, the equipment shoul

42、d function without undue degradation in an electromagnetic environment typical for the locations where it is intended to be operated. In this respect the standard specifies three different types of electromagnetic environment and the levels for immunity. More detailed information about issues relate

43、d to electromagnetic environments are given in IEC 61000-2-5. Special risks, involving for example nearby or direct lightning strikes, circuit-breaking, or exceptionally high electromagnetic radiation in close proximity, are not covered. Complex electric and/or electronic systems should require EMC

44、planning in all phases of their design and installation, taking into consideration the electromagnetic environment, any special requirements, and the severity of failures. This part of IEC 61326 specifies the EMC requirements that are generally applicable to all equipment within its scope. For certa

45、in types of equipment, these requirements will be supplemented or modified by the special requirements of one, or more than one, particular part within IEC 61326-2 series. These should be read in conjunction with the IEC 61326-1 requirements. 61326-1 IEC:2012 7 ELECTRICAL EQUIPMENT FOR MEASUREMENT,

46、CONTROL AND LABORATORY USE EMC REQUIREMENTS Part 1: General requirements 1 Scope This part of IEC 61326 specifies requirements for immunity and emissions regarding electro- magnetic compatibility (EMC) for electrical equipment, operating from a supply or battery of less than 1 000 V a.c. or 1 500 V

47、d.c. or from the circuit being measured. Equipment intended for professional, industrial-process, industrial-manufacturing and educational use is covered by this part. It includes equipment and computing devices for measurement and test; control; laboratory use; accessories intended for use with the

48、 above (such as sample handling equipment), intended to be used in industrial and non-industrial locations. Computing devices and assemblies and similar equipment within the scope of Information Technology Equipment (ITE) and complying with applicable ITE EMC standards may be used in systems within

49、the scope of this part of IEC 61326 without additional testing, if they are suitable for the intended electromagnetic environment. It is generally considered that this standard takes precedence over the corresponding generic EMC standards. The following equipment is covered by this standard. a) Electrical measurement and test equipment This is equipment which, by electrical means, measures, indicates or
