Welding equipment not constructed in compliance with
EN/IEC60974-1 might not meet all the requirements of this
standard. In this case, specify the following in the test report:
• Requirements not met
• Extent of the requirements not met
• Risk assessment to be concluded
• Corrective measures
The test report shall enable the owner to make an appropriate
decision on the further use of the device.
