IEC EN 60974-10 Arc Welding Equipment - Part 10: Test Standard for Electromagnetic Compatibility (EMC) Requirements

EUROLAB, together with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of IEC EN 60974-10 test. IEC EN 60974-10 applies to arc welding and related processes, including power supplies and ancillary equipment such as wire feeders, liquid cooling systems, arc striking and stabilizing devices, and chargers for battery powered equipment.

This part of IEC EN 60974 states:

• Applicable standards and test methods for radio frequency (RF) emissions;
• Applicable standards and test methods for harmonic current emission, voltage fluctuations and flickering;
• Immunity requirements and test methods for permanent and temporary, conducted and radiated disturbances, including electrostatic discharges.

The tests will be carried out on fully assembled equipment, which represents mass production. The tests shall be carried out within the specified operating conditions and at the rated supply voltage and frequency given in IEC 60974-1 or IEC 60974-6. The results for RF emission and immunity at 50 Hz are valid for the same model operating at 60 Hz and vice versa.

In any case where retesting of equipment is necessary to demonstrate compliance with this standard, the originally selected test setup should be used to ensure consistency of results, unless otherwise agreed by the manufacturer.

If, due to the design of the arc welding equipment, these tests cannot be performed as described, the manufacturer's recommendations (for example, temporary disabling or deactivation of control circuits) should be followed to achieve these test purposes. Any temporary changes to arc welding equipment shall be documented.

If auxiliary equipment can be connected to the welding power supply, the welding power supply should be tested with the minimum configuration of auxiliary equipment required to operate the ports. If the source power supply has a large number of similar ports or many similarly connected ports, a sufficient number should be selected to simulate real operating conditions and to ensure that all different termination types are covered.
