Resistance welding equipment - Part 2: Electromagnetic compatibility (EMC) requirements (IEC 62135-2:2020)

This part of IEC 62135 is applicable to equipment for resistance welding and allied processes
which are connected to mains supplies with rated voltages up to 1 000 V AC RMS. This
document does not define safety requirements.
Resistance welding equipment type tested in accordance with, and which has met the
requirements of, this document, is deemed to be in compliance for all applications.
The frequency range covered is from 0 Hz to 400 GHz.
Arc welding equipment containing a radio receiver or transmitter is within the scope of this
document. Additional requirements for such equipment is specified in Annex D.
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 product EMC standard for resistance welding equipment takes precedence over all
aspects of the generic standards and no additional EMC tests are required or necessary.
NOTE 1 Typical allied processes are resistance hard and soft soldering or resistance heating achieved by means
comparable to resistance welding equipment.
NOTE 2 Limit values are specified for only part of the frequency range.
Resistance welding equipment are classified as Class A and Class B equipment.
This part of IEC 62135 specifies
a) test methods to be used in conjunction with CISPR 11:2015, CISPR 11:2015/AMD1:2016
and CISPR 11:2015/AMD2:2019 to determine radio-frequency (RF) emission;
b) relevant standards and test methods for harmonic current emission, voltage fluctuation
and flicker;
c) additional requirements for equipment powered by internal or external batteries (Annex C).
NOTE 3 The limits in this document cannot, however, provide full protection against interference to radio and
television reception when the resistance welding equipment is used closer than 30 m to the receiving antenna(e).
NOTE 4 In special cases, when highly susceptible apparatus is being used in close proximity, additional
mitigation measures are sometimes employed to further reduce the electromagnetic emissions.
NOTE 5 The origins of the limit values in this document are summarized in Annex A.
This part of IEC 62135 also defines immunity requirements and test methods for continuous
and transient, conducted and radiated disturbances including electrostatic discharges.
NOTE 6 These requirements do not, however, cover extreme cases which are extremely rare.

Oprema za uporovno varjenje - 2. del: Zahteve za elektromagnetno združljivost (EMC) (IEC 62135-2:2020)

Ta del standarda IEC 62135 se uporablja za opremo za uporovno varjenje in povezane procese, ki so povezani z omrežnim napajanjem in imajo nazivno napetost do 1000 V izmenične napetosti RMS. Ta dokument ne določa varnostnih zahtev.
Oprema za uporovno varjenje, ki je tipsko preskušena v skladu s tem dokumentom in izpolnjuje njegove zahteve, je skladna za vse vrste uporabe.
Zajet frekvenčni razpon je od 0 Hz do 400 GHz.
Oprema za obločno varjenje z radijskim sprejemnikom ali oddajnikom spada na področje uporabe tega dokumenta. Dodatne zahteve za takšno opremo so določene v dodatku D.
Zahteve glede elektromagnetnega sevanja iz tega dokumenta niso namenjene za uporabo za namerne prenose iz radijskega oddajnika, kot ga opredeljuje ITU, in morebitna neželena oddajanja, povezana s temi namernimi prenosi.
Ta standard za izdelek v zvezi z elektromagnetno združljivostjo za opremo za uporovno varjenje ima prednost pred vsemi vidiki splošnih standardov, pri čemer dodatni preskusi elektromagnetne združljivosti niso potrebni ali zahtevani.
OPOMBA 1: Običajni povezani procesi so uporovno trdo ali mehko spajkanje ali uporovno gretje, ki se doseže na način, primerljiv z opremo za uporovno varjenje.
OPOMBA 2: Mejne vrednosti so določene samo za del frekvenčnega razpona.
Oprema za uporovno varjenje se uvršča v razred A in razred B.
Ta del standarda IEC 62135 določa:
a) preskusne metode, ki se uporabljajo skupaj s standardi CISPR 11:2015, CISPR 11:2015/AMD1:2016 in CISPR 11:2015/AMD2:2019 za določevanje radiofrekvenčnih (RF) emisij;
b) ustrezne standarde in preskusne metode za emisije harmonskih tokov, spremembe ter nihanje napetosti;
c) dodatne zahteve za opremo, ki se napaja prek notranjih ali zunanjih baterij (dodatek C).
OPOMBA 3: Omejitve v tem dokumentu pa ne morejo zagotoviti popolne zaščite pred motnjami radijskega in televizijskega sprejema, kadar se oprema za uporovno varjenje uporablja bližje kot 30 m od sprejemne antene.
OPOMBA 4: V posebnih primerih, kadar se v neposredni bližini uporablja izredno občutljiv aparat,
se včasih izvedejo dodatni ukrepi za zmanjšanje elektromagnetnih emisij.
OPOMBA 5: Izvor mejnih vrednosti v tem dokumentu je povzet v dodatku A.
Ta del standarda IEC 62135 določa tudi zahteve glede odpornosti in preskusne metode za neprekinjene in začasne ter vodene in sevane motnje, vključno z elektrostatičnimi razelektritvami.
OPOMBA 6: Te zahteve pa ne obravnavajo skrajnih primerov, ki so izredno redki.

Part 2: 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 62135-2 has been prepared by IEC technical committee 26:

Electric welding.

This third edition cancels and replaces the second edition published in 2015. This edition

constitutes a technical revision.

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

edition:
a) update of the applicable limits related to the updated references;
b) implementation of radiated magnetic field requirements.

RESISTANCE WELDING EQUIPMENT –
Part 2: Electromagnetic compatibility (EMC) requirements
1 Scope

This part of IEC 62135 is applicable to equipment for resistance welding and allied processes

which are connected to mains supplies with rated voltages up to 1 000 V AC RMS. This

document does not define safety requirements.

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

requirements of, this document, is deemed to be in compliance for all applications.

The frequency range covered is from 0 Hz to 400 GHz.

Arc welding equipment containing a radio receiver or transmitter is within the scope of this

document. Additional requirements for such equipment is specified in Annex D.

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 product EMC standard for resistance welding equipment takes precedence over all

aspects of the generic standards and no additional EMC tests are required or necessary.

NOTE 1 Typical allied processes are resistance hard and soft soldering or resistance heating achieved by means

comparable to resistance welding equipment.
NOTE 2 Limit values are specified for only part of the frequency range.
Resistance welding equipment are classified as Class A and Class B equipment.
This part of IEC 62135 specifies

a) test methods to be used in conjunction with CISPR 11:2015, CISPR 11:2015/AMD1:2016

and CISPR 11:2015/AMD2:2019 to determine radio-frequency (RF) emission;

b) relevant standards and test methods for harmonic current emission, voltage fluctuation

and flicker;

c) additional requirements for equipment powered by internal or external batteries (Annex C).

NOTE 3 The limits in this document cannot, however, provide full protection against interference to radio and

television reception when the resistance welding equipment is used closer than 30 m to the receiving antenna(e).

NOTE 4 In special cases, when highly susceptible apparatus is being used in close proximity, additional

mitigation measures are sometimes employed to further reduce the electromagnetic emissions.

NOTE 5 The origins of the limit values in this document are summarized in Annex A.

This part of IEC 62135 also defines immunity requirements and test methods for continuous

and transient, conducted and radiated disturbances including electrostatic discharges.

NOTE 6 These requirements do not, however, cover extreme cases which are extremely rare.
