The standard for the use of welding equipment.
Ask Wesley.
The IEC 60974-4 is the European standard for welding equipment. Welding equipment must be periodically inspected according to the NEN-EN-IEC 60974-4 standard to guarantee its safe operation. Huisman Etech Experts can conduct a NEN-EN-IEC 60974-4 inspection for you, testing electrical safety aspects such as insulation resistance, earth connections and leakage current. The inspection consists of a visual inspection, measurements, tests and a test with a safety meter. Our findings are recorded in an inspection certificate, and the approved devices are labelled with an inspection sticker.
