Arc welding equipment - Part 10: Electromagnetic compatibility (EMC) requirements (IEC 60974-10:2020)

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 60974-10:2020)

Standard IEC 60974-10:2014 določa: a) ustrezne standarde in preskusne metode za radiofrekvenčne (RF) emisije; b) ustrezne standarde in preskusne metode za emisije harmonskih tokov, spremembe ter nihanje 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, kot so na primer podajalniki žice, hladilni sistemi s tekočino ter obločni udari in stabilizatorji. Ta tretja izdaja razveljavlja in nadomešča drugo izdajo, objavljeno leta 2007, in predstavlja tehnično popravljeno izdajo. Ta izdaja vključuje naslednje pomembne tehnične spremembe glede na prejšnjo izdajo:  – vključitev izbirne uporabe ločilnega omrežja in obremenitve zunaj preskusne komore; – vključitev alternativne postavitve za preskušanje za prenosno opremo; – vključitev preskusnih pogojev za kompleksne krmilne naprave, hladilne sisteme s tekočino ter obločne udare in stabilizatorje; – posodobitev veljavnih mejnih vrednosti z zvezi s posodobljenim sklicevanjem na standard CISPR 11; – izključitev uporabe zmanjševanja mejnih vrednosti radiofrekvenčnih emisij; – posodobitev veljavnih mejnih vrednosti za harmonsko nihanje in nihanje napetosti ter vključitev diagramov poteka v zvezi s posodobljenim sklicevanjem na standarda IEC 61000-3-11 in IEC 61000-3-12; – posodobitev zahtev glede upadov napetosti v zvezi s posodobljenim sklicevanjem na standarda IEC 61000-4-11 in IEC 61000-4-34; – posodobitev informativnega dodatka za namestitev in uporabo; – vključitev simbolov za označevanje razreda radiofrekvenčne opreme in omejitev uporabe.

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

ARC WELDING EQUIPMENT –
Part 10: Electromagnetic compatibility (EMC) requirements
1 Scope

This part of IEC 60974 is applicable to equipment for arc welding and allied processes,

including power sources and ancillary equipment, for example wire feeders, liquid cooling

systems, arc striking and stabilizing devices and chargers for battery powered equipment.

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

NOTE 2 This document 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 containing a radio receiver or transmitter is within the scope of this

document.

The radiated emission requirements in this document are not intended to be applicable to the

intentional transmissions from a radio transmitter as defined by the ITU nor to any spurious

emissions related to these intentional transmitters.
This document 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;

d) additional requirements for equipment powered by internal or external batteries

(Annex D);

e) additional requirements for equipment containing radio frequency transmitters/receivers

(Annex E).

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

set in, this document is considered to be in compliance for all applications.
