Arc welding equipment - Part 10: Electromagnetic compatibility (EMC) requirements

IEC 60974-10:2014 specifies a) applicable standards and test methods for radio-frequency (RF) emissions; b) applicable standards and test methods for harmonic current emission, voltage fluctuations and flicker; c) immunity requirements and test methods for continuous and transient, conducted and radiated disturbances including electrostatic discharges. This standard is applicable to equipment for arc welding and allied processes, including power sources and ancillary equipment, for example wire feeders, liquid cooling systems and arc striking and stabilizing devices. This third edition cancels and replaces the second edition published in 2007 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - inclusion of optional use of a decoupling network and a load outside the test chamber; - inclusion of an alternative test setup for portable equipment; - inclusion of test conditions for complex controls, liquid cooling systems and arc striking and stabilizing devices; - update of the applicable limits related to the updated reference to CISPR 11; - exclusion of the use of narrow band relaxations for RF emission limits; - update of the applicable limits for harmonics and flicker and inclusion of flow-charts related to the updated reference to IEC 61000-3-11 and IEC 61000-3-12; - update of the requirements for voltage dips related to the updated reference to IEC 61000-4-11 and IEC 61000-4-34; - update of the informative annex for installation and use; - inclusion of symbols to indicate the RF equipment class and restrictions for use.

Oprema za obločno varjenje - 10. del: Zahteve za elektromagnetno združljivost (EMC) (IEC 60974-10:2014)

Standard EN IEC 60974-10 določa a) ustrezne standarde in preskusne metode za radiofrekvenčne (RF) emisije; b) ustrezne standarde in preskusne metode za emisijo harmonskih tokov, spremembe ter nihanja napetosti; c) zahteve glede odpornosti ter preskusne metode za trajne in prehodne, sevalne in prevajalne motnje, vključno z elektrostatičnimi praznitvami. Ta standard se uporablja za opremo za obločno varjenje in povezane procese, vključno z viri napajanja in pomožno opremo, na primer podajalniki žice, hladilni sistemi s tekočino ter obločni udari in stabilizatorji. Oprema za obločno varjenje, ki je tipsko preskušena v skladu s tem standardom in izpolnjuje njegove zahteve, se šteje za skladno za vse uporabe.

ARC WELDING EQUIPMENT –
Part 10: Electromagnetic compatibility (EMC) requirements
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 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 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, 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.

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 60974-10 has been prepared by IEC technical committee 26:

Electric welding.

This third edition cancels and replaces the second edition published in 2007 and constitutes a

technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

• inclusion of optional use of a decoupling network and a load outside the test chamber;

• inclusion of an alternative test setup for portable equipment;

• inclusion of test conditions for complex controls, liquid cooling systems and arc striking

and stabilizing devices;
• update of the applicable limits related to the updated reference to CISPR 11;
• exclusion of the use of narrow band relaxations for RF emission limits;
---------------------- Page: 12 ----------------------
SIST EN 60974-10:2014
60974-10 © IEC:2014 – 5 –

• update of the applicable limits for harmonics and flicker and inclusion of flow-charts

related to the updated reference to IEC 61000-3-11 and IEC 61000-3-12;

• update of the requirements for voltage dips related to the updated reference to

IEC 61000-4-11 and IEC 61000-4-34;
• update of the informative annex for installation and use;

• inclusion of symbols to indicate the RF equipment class and restrictions for use.

The text of this standard is based on the following documents:
FDIS Report on voting
26/519/FDIS 26/526/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.

The list of all the parts of the IEC 60974 series, under the general title Arc welding equipment,

can be found on the IEC web site.

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
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

Part 10: Electromagnetic compatibility (EMC) requirements
1 Scope
This part of IEC 60974 specifies
a) applicable standards and test methods for radio-frequency (RF) emissions;

b) applicable standards and test methods for harmonic current emission, voltage fluctuations

and flicker;

c) immunity requirements and test methods for continuous and transient, conducted and

radiated disturbances including electrostatic discharges.

This standard is applicable to equipment for arc welding and allied processes, including power

sources and ancillary equipment, for example wire feeders, liquid cooling systems and arc

striking and stabilizing devices.
NOTE 1 Allied processes are, for example, plasma cutting and arc stud welding.

NOTE 2 This standard does not specify basic safety requirements for arc welding equipment such as protection

against electric shock, unsafe operation, insulation coordination and related dielectric tests.

Arc welding equipment type tested in accordance with, and which has met the requirements
