scope:

This part of IEC 62822, which is a product family standard, applies to equipment for resistance welding, arc welding and allied processes designed for occupational use by professionals and for use by laymen.

NOTE 1 Typical allied processes are resistance hard and soft soldering, resistance heating by means comparable to resistance welding equipment, electric arc cutting and arc spraying.

The frequency range covered is 0 Hz to 300 GHz.

This product family standard specifies assessment methods and criteria to evaluate electromagnetic field (EMF) emissions of electric welding equipment with regard to national and international requirements for human exposure to EMF.

NOTE 2 Magnetic fields generated by the operation of welding equipment and the resulting non-thermal effects are the main assessment concern.

This product family standard does not define requirements and methods for workplace assessment regarding the risks arising from electromagnetic fields. However, the EMF exposure data that results from the application of this product family standard can be used to assist in workplace assessment.

NOTE 3 The equipment manufacturer is unaware of the overall exposure environment in which the equipment will be used (e.g. multiple sources) and is not responsible for all requirements for workplace assessment (e.g. information and training of workers, design and layout of the workplace).

Other standards may apply to products covered by this standard. In particular this standard cannot be used to demonstrate electromagnetic compatibility with other equipment. It does not specify any product safety requirements other than those specifically related to human exposure to electromagnetic fields.
