1 Scope

This standard specifies the radiated electromagnetic field and arc welding equipment under normal operating conditions generated strong test conditions and evaluation method. Frequency of electromagnetic radiation involved is less than 1MHz. According to the current actual ability to detect electromagnetic radiation, the frequency is detected from 10Hz (or less) to 400kHz (or higher) range. This standard applies to electrical resistance welding and arc welding equipment.
