适用范围：This product family standard applies to equipment for resistance welding, arc welding and alliedprocesses 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 andstabilising devices.NOTE 1 Allied processes are for example resistance hard and soft soldering, resistance heating by means comparable toresistance 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 ofDirective 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 additionalrequirements 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 ensurethat electrical equipment may be placed on the market only if, having been constructed in accordance with good engineeringpractice in safety matters in force in the Community.This product family standard may also be used for assessment regarding the requirements ofDirective 2004/40/EC [3] on the minimum health and safety requirements regarding the exposure ofworkers to the risks arising from physical agents (electromagnetic fields) or Recommendation1999/519/EC [2] on the limitation of exposure of the general public to electromagnetic fields, providedthat no other relevant field sources are present in close proximity. If other relevant field sources arepresent, additional assessment is necessary.NOTE 3 It should be noted that the supplier of specific equipment might not know the overall exposure environment in whichthe equipment is being used. This product family standard can only be used to assess human exposure from the specificequipment 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 thisstandard can not be used to demonstrate electromagnetic compatibility with other equipment; nordoes it specify any product safety requirements other than those specifically related to humanexposure to electromagnetic fields.NOTE 5 Procedures to demonstrate compliance are not specified for the whole frequency range.
