This product family standard applies to equipment for resistance welding, arc welding and allied
processes designed for use in industrial or domestic environments, including welding power sources,
wire feeders and ancillary equipment, e.g. torches, liquid cooling systems and arc striking and
stabilising devices.
NOTE 1 Allied processes are for example 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 may be used to demonstrate compliance with the requirements of
Directive 2006/95/EC [1] (needed for placing electric welding equipment on the European market),
with regard to the limitation of human exposure to electromagnetic fields (EMF). There are additional
requirements in the Directive, which are not included in this product family standard.
NOTE 2 The Directive 2006/95/EC [1], Article 2, stipulates that the Member States take all appropriate measures to ensure that electrical equipment may be placed on the market only if, having been constructed in accordance with good engineering practice in safety matters in force in the Community.
This product family standard may also be used for assessment regarding the requirements of Directive 2004/40/EC [3] on the minimum health and safety requirements regarding the exposure of
workers to the risks arising from physical agents (electromagnetic fields) or Recommendation 1999/519/EC [2] on the limitation of exposure of the general public to electromagnetic fields, provided that no other relevant field sources are present in close proximity. If other relevant field sources are present, additional assessment is necessary.
NOTE 3 It should be noted that the supplier of specific equipment might not know the overall exposure environment in which the equipment is being used. This product family standard can only be used to assess human exposure from the specific equipment under evaluation when being used in accordance with the suppliers guidelines.
NOTE 4 Assessment procedures for workplaces with multiple field-sources may be found in EN 50499 [7].
Other standards may apply to products covered by this product family standard. In particular this
standard can not be used to demonstrate electromagnetic compatibility with other equipment; nor
does it specify any product safety requirements other than those specifically related to human
exposure to electromagnetic fields.
NOTE 5 Procedures to demonstrate compliance are not specified for the whole frequency range.
