RESISTANCE WELDING EQUIPMENT –

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, 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
The text of this standard is based on the following documents:
CDV Report on voting
26/342/CDV 26/357/RVC

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 62135 series, under the general title Resistance welding
equipment, can be found on the IEC website.

The committee has decided that the contents of this publication will remain unchanged until
the maintenance result 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.

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, shall be 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 (r.f.)
emission;
b) relevant standards and test methods for harmonic current emission, voltage fluctuation
and flicker.
NOTE 3 The limits in this standard may not, 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 may have to be 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.
