Overview
SIST EN IEC 60974-10:2022/kFprA1:2025 is an important amendment to the international standard covering arc welding equipment, specifically Part 10 which addresses electromagnetic compatibility (EMC) requirements. Published by the CLC and developed under the International Electrotechnical Commission (IEC) technical committee TC 26, this amendment updates and aligns EMC assessment and test procedures for arc welding devices. The update reflects evolving technological practices and ensures compatibility with modern radio and electronic components often integrated into welding equipment.
The amendment harmonizes the latest EMC directives, introduces clearer criteria for portable equipment, and refines documentation and testing methods. It replaces prior versions of IEC 60974-10, consolidating requirements that manufacturers, testing laboratories, and regulatory bodies rely upon to confirm equipment compliance with EMC standards.
Key Topics
Scope and Inclusion of Radio-Enabled Equipment
This amendment expands the scope to explicitly include arc welding equipment with embedded radio transmit/receive functions (host equipment with radio functionality). It clarifies that while intentional radio transmissions fall under ITU regulations, the standard applies to all other emission requirements, including intermodulation effects between radio and non-radio subassemblies.Updated Terminology and Definitions
Important new terms such as "portable equipment," "equipment with radio functionality," "radio device," "radio module," and "radio transmitter" have been precisely defined. For example, “portable” refers to devices capable of being carried by a single person, which impacts testing setups and emission criteria.Test Instruments and Methods
The amendment specifies measurement instrumentation requirements in accordance with CISPR 16 series standards (CISPR 16-1-1, 16-1-2, and 16-1-4) to assess conducted and radiated electromagnetic emissions accurately. It describes artificial mains network (AMN) configurations, voltage probe characteristics, antenna types for different frequency ranges (from 30 MHz to several GHz), and coupling/decoupling network (CDN) usage to replicate real-world operational environments.Test Set-Up and Procedures
The document offers detailed instructions for configuring emission and immunity test setups for both portable and non-portable arc welding equipment. It includes guidance on positioning equipment under test (EUT), bundling excess cable lengths, ensuring standard distances between antennas and load, and simulating arc welding operation using conventional loads. Ancillary equipment like wire feeders and remote controls must also be tested following specified cable lengths and connection methods.Alignment with CISPR 11 7th Edition
The amendment aligns emission limits and measurement methods with the latest 7th edition of CISPR 11, ensuring consistent, up-to-date EMC handling for industrial, scientific, and medical (ISM) equipment categories that include arc welding apparatus.Documentation and Informative Annexes
Clause 8 on documentation for purchasers and users has been transformed into an informative annex, providing clearer guidance on necessary information accompanying equipment-supporting compliance, safe use, and regulatory adherence.
Applications
This amendment serves manufacturers of arc welding equipment, including:
- Welding machinery producers integrating radio modules for remote control or data exchange.
- Testing and certification laboratories conducting EMC evaluations on welding systems and ancillary components.
- Regulatory authorities enforcing EMC compliance within industrial and manufacturing settings.

10 FOREWORD
11 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
12 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
13 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
14 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
15 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
16 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
17 in the subject dealt with may participate in this preparatory work. International, governmental and non-
18 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
19 with the International Organization for Standardization (ISO) in accordance with conditions determined by
20 agreement between the two organizations.
21 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
22 consensus of opinion on the relevant subjects since each technical committee has representation from all
23 interested IEC National Committees.
24 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
25 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
26 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
27 misinterpretation by any end user.
28 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
29 transparently to the maximum extent possible in their national and regional publications. Any divergence
30 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
31 the latter.
32 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
33 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
34 services carried out by independent certification bodies.
35 6) All users should ensure that they have the latest edition of this publication.
36 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
37 members of its technical committees and IEC National Committees for any personal injury, property damage or
38 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
39 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
40 Publications.
41 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
42 indispensable for the correct application of this publication.
43 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
44 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
45 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s),
46 which may be required to implement this document. However, implementers are cautioned that this may not
47 represent the latest information, which may be obtained from the patent database available at
48 https://patents.iec.ch. IEC shall not be held responsible for identifying any or all such patent rights.
