27、) 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 electrica
28、l 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 technica
29、l 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 Organiza
30、tion 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 co
31、mmittee 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
32、 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 an
33、d 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 a
34、nd, in some areas, access to IEC marks of conformity. IEC is not responsible for 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 o
35、r 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) and expenses arising out of the publication, us
36、e 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. 9) Attention is drawn to the possibility that
37、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. DISCLAIMER This Redline version is not an official IEC Standard and is intended only to provide the user with an indication of what chang
38、es have been made to the previous version. Only the current version of the standard is to be considered the official document. This Redline version provides you with a quick and easy way to compare all the changes between this standard and its previous edition. A vertical bar appears in the margin w

IEC 61326-3-1:2017 RLV IEC 2017 5 International Standard IEC 61326-3-1 has been prepared by subcommittee 65A: System aspects, of IEC technical committee 65: Industrial-process measurement, control a
40、nd automation. This second edition cancels and replaces the first edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: extension of the frequency range up to 6 GHz for the rad
41、io-frequency electromagnetic field test according to IEC 61000-4-3, replacement of the performance criterion FS with DS according to the generic standard IEC 61000-6-7, adding Table 1 Aspects to be considered during application of performance criterion DS, including immunity tests for devices with c
42、urrent consumption 16 A according to IEC 61000-4-34, updating Table 8 Frequency ranges of mobile transmitters and ISM equipment, updating Figure A.1 and Figure 1 for better readability. IEC 61326-3-1 is to be read in conjunction with IEC 61326-1. The text of this standard is based on the following d
43、ocuments: FDIS Report on voting 65A/819/FDIS 65A/825/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/IEC Directives, Part 2. A list of all the parts of
44、 the IEC 61326 series, under the general title Electrical equipment for measurement, control and laboratory use EMC requirements, 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 websi
45、te under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

Users should therefore print this document using a colour printer. 6 IEC 61326-3-1:2017 RLV IEC 2017 INTRODUCTION Functional safety is that part of the overall safety relating to the equipment under control (EUC) and the EUC c
47、ontrol system which depends on the correct functioning of the electrical safety-related systems. To achieve this, all items of equipment of the safety-related system which are involved in the performance of the safety functions must behave in a specified manner under all relevant conditions. The IEC
48、 basic safety publication for functional safety of electrical/electronic/programmable electronic safety-related systems is IEC 61508. It sets the overall requirements to achieve functional safety. Sufficient immunity to electromagnetic disturbances is one of those requirements. The concept of IEC 61
49、508 distinguishes between the consideration of the application and the design of safety-related electrical and electronic systems. The interface between both is The overall safety requirements specification (SRS). It specifies all relevant requirements of the intended application, as follows: a) definition of the safety functions, based on a risk assessment of the intended application (which functions are intended to reduce risk); b) appropr
