15、ents of the SABS .61326-1 IEC:2005 5 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ ELECTRICAL EQUIPMENT FOR MEASUREMENT, CONTROL AND LABORATORY USE EMC REQUIREMENTS Part 1: General requirements FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardizat

16、ion 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 Internatio

17、nal 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 t

18、his 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 tw

19、o 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 th

20、e 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 misinter

21、pretation 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

22、or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of t

23、his publication. 7) No liability shall attach 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 i

24、ndirect, 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) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for

25、 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. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61326-1 has been p

26、repared by subcommittee 65A: System aspects, of IEC technical committee 65: Industrial-process measurement and control. The IEC 61326 series cancels and replaces IEC 61326:2002 and constitutes a technical revision. The text of this standard is based on the following documents: FDIS Report on voting

34、326-1 IEC:2005 9 INTRODUCTION Instruments and equipment within the scope of this standard may often be geographically widespread and may have to operate under a wide range of environmental conditions. The limitation of undesired electromagnetic emissions ensures that no other equipment, installed ne

35、arby, 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 has to function without undue degradation in a typical elect

36、romagnetic environment. The limit values for immunity specified in this standard have been chosen under this assumption. Special risks, involving for example nearby or direct lightning strikes, circuit-breaking, or exceptionally high electromagnetic radiation in close proximity, are not covered. Com

37、plex electric and/or electronic systems require EMC 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 app

38、licable to all equipment within its scope. For certain 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. These should be read in conjunction with the IEC 61326-1 requirements. SANS 61326-1

40、L EQUIPMENT FOR MEASUREMENT, 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 t

41、han 1 000 V a.c. or 1 500 V d.c. or from the circuit being measured, intended for professional, industrial-process, industrial-manufacturing and educational use, including equipment and computing devices for measurement and test; control; laboratory use; accessories intended for use with the above (

42、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 can be used in systems within the scop

43、e of this part of IEC 61326 without additional testing, if it is suitable for the intended electromagnetic environment. This product family standard takes precedence over generic standards. The following equipment is covered in this standard. a) Electrical measurement and test equipment This is equi

44、pment, which by electrical means measures, indicates or records one or more electrical or non-electrical quantities, also non-measuring equipment such as signal generators, measurement standards, power supplies and transducers. b) Electrical control equipment This is equipment, which controls one or

45、 more output quantities to specific values, with each value determined by manual settings, by local or remote programming, or by one or more input variables. This includes Industrial Process Measurement and Control (IPMC) equipment, which consists of devices such as: process controllers and regulato

46、rs; programmable controllers; power supply units for equipment and systems (centralized or dedicated); analogue/digital indicators and recorders; process instrumentation; transducers, positioners, intelligent actuators, etc. SANS 61326-1:2007This s tandard may only be used and printed by approved su

47、bscription and freemailing clients of the SABS .61326-1 IEC:2005 13 c) Electrical laboratory equipment This is equipment which measures, indicates monitors or analyses substances, or is used to prepare materials, and includes In Vitro Diagnostic (IVD) equipment. This equipment may also be used in ar

48、eas other than laboratories, for example self-test IVD equipment may be used in the home. This standard is applicable to equipment for use in residential, commercial and light-industrial environments, according to IEC 61000-6-1; equipment for use in industrial locations; equipment for use in laborat
