Overview

EN IEC 60974-13:2021 (CLC) is Part 13 of the IEC 60974 series covering arc welding equipment specifically for welding current return clamps (also called work clamps or return current clamps). This 2021 edition supersedes EN 60974-13:2011 and defines safety and performance requirements for clamps that make an electrical connection to the workpiece without using tools. The standard is not applicable to clamps for underwater welding or plasma cutting and does not set requirements for welding cables.

Key topics and technical requirements

  • Scope and definitions – Clarifies terminology (WELDING CURRENT RETURN CLAMP, RATED CURRENT, RETAINING MEANS) and relationship to IEC 60974-1.
  • Environmental conditions – Operation: ambient air temperature −10 °C to +40 °C; relative humidity up to 50% at 40 °C and up to 90% at 20 °C. Storage/transport: −20 °C to +55 °C.
  • Thermal rating – Defines RATED CURRENT (manufacturer-assigned current at 60% duty cycle) and limits on temperature rise under specified test conditions.
  • Electrical safety – Protection against electric shock and acceptable voltage drop between clamp and workpiece.
  • Mechanical requirements – Tests and design requirements for retaining means, cable entry and connection, and drop-withstand capability to ensure secure, durable clamping in practical use.
  • Performance tests – Type-test conditions (ambient 10 °C to 40 °C), test sequence, measuring instruments and test currents (updated values in Table 1 corrected to 40 °C).
  • Resistance to hot objects – Test method and device for exposure to hot workpiece environments.
  • Marking and instructions – Mandatory marking and user instructions to support safe installation and operation.

Applications and who uses it

EN IEC 60974-13:2021 is intended for:

  • Manufacturers and designers of welding current return clamps who need compliance criteria for safety, durability and performance.
  • Test laboratories and conformity assessment bodies performing type tests and certification.
  • Procurement and quality engineers selecting clamps specified for industrial welding equipment.
  • Health & safety and maintenance teams ensuring clamps meet environmental, thermal and mechanical requirements for workplace safety. It supports safe integration of return clamps into welding setups across fabrication, construction and maintenance environments (excluding underwater welding and plasma cutting).

harmonized standards in the field of the Low Voltage Directive, M/511, to provide one voluntary means
of conforming to safety objectives of Directive 2014/35/EU of the European Parliament and of the
Council of 26 February 2014 on the harmonization of the laws of the Member States relating to the
making available on the market of electrical equipment designed for use within certain voltage limits
[2014 OJ L96].
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard given in Table ZZ.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding safety objectives of
that Directive, and associated EFTA regulations.

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

EN IEC 60974-13:2021 is a standard that applies to welding current return clamps used in arc welding. These clamps are designed to create an electrical connection with the workpiece without the need for tools. However, the standard does not cover clamps used for underwater welding and plasma cutting. The document outlines safety and performance requirements for these clamps, but it does not provide specifications for welding cables.
