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

Ta del standarda IEC 62135 se uporablja za opremo za uporovno varjenje in povezane procese, ki so povezani z glavnim napajanjem ter imajo nazivno napetost do 1000 V izmenične napetosti efektivne vrednosti. Ta standard ne določa varnostnih zahtev. Oprema za uporovno varjenje, ki je tipsko preskušena v skladu s tem standardom in izpolnjuje njegove zahteve, se šteje za skladno za vse uporabe. Zajet frekvenčni razpon je od 0 Hz do 400 GHz. Ta standard za izdelek v zvezi z elektromagnetno združljivostjo za opremo za uporovno varjenje ima prednost pred vsemi vidiki splošnih standardov, pri čemer niso potrebni ali zahtevani dodatni preskusi elektromagnetne združljivosti.
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 standardom CISPR 11 za določevanje radiofrekvenčnih (RF) emisij;
b) ustrezne standarde in preskusne metode za emisije harmonskih tokov, spremembe ter nihanja napetosti.
OPOMBA 3: Omejitve v tem standardu 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 uporabljajo dodatni ukrepi za ublažitev za omejevanje elektromagnetnih emisij.
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 5: 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 second edition cancels and replaces the first edition published in 2007 and constitutes a

technical revision.

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

edition:
– 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 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;

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 a.c. r.m.s. This

standard does not define safety requirements.

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

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

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

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 to determine radiofrequency (RF)

emission;

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

and flicker.

NOTE 3 The limits in this standard 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.

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

and transient, conducted and radiated disturbances including electrostatic discharges.

NOTE 5 These requirements do not, however, cover extreme cases which are extremely rare.
