适用范围：This European Standard applies to equipment for resistance welding and allied processes designedfor use in industrial or domestic environments.NOTE 1 Typical allied processes are resistance hard and soft soldering or resistance heating achieved by means comparableto resistance welding equipment.This European Standard establishes a suitable evaluation method for determining the electromagneticfields in the space around the equipment and defines standardized operating conditions andmeasuring distances. It provides a method to show conformity with guidelines or requirementsconcerning human exposure to electromagnetic fields.The Directive 2006/95/EC of the European Parliament and the Council [1], Article 2, stipulates that theMember States take all appropriate measures to ensure that electrical equipment may be placed onthe market only if, having been constructed in accordance with good engineering practice in safetymatters in force in the Community, it does not endanger the safety of persons, domestic animals orproperty when properly installed and maintained and used in applications for which is was made. Theprincipal elements of those safety objectives are listed in Annex I Clause 2.b. This standard may beused in conjunction with EN 50445 for demonstration of conformity to the Council Directive withreference to human exposure to electromagnetic fields (EMF). There are additional requirementscovered by Article 2 and Annex I Clause 2.b, which are not included in this document.The Council Recommendation 1999/519/EC [2] provides Basic Restrictions and Derived referencelevels for exposure of the general public. This standard may be used for demonstration of resistancewelding equipment conformity to the Council Recommendation on this basis, but there may beadditional specific national or international requirements which are not included.The ICNIRP Guidelines [3], on limits of exposure to static magnetic fields as well as for limitingexposure in time varying electric, magnetic and electromagnetic fields, provide Basic restrictions andDerived reference levels for both occupational and general exposure. This standard may be used fordemonstration of equipment conformity to ICNIRP Guidelines on this basis, but there may beadditional national or international requirements which are not included.It is also possible to use this document as a basis to demonstrate conformity of resistance weldingequipment to other national and international guidelines or requirements with regard to humanexposure from EMF, for example Council Directive 2004/40/EC [4] on the minimum health and safetyrequirements regarding the exposure of workers to the risk arising from physical agents(electromagnetic fields), or the requirements of the Directive 98/37/EC [5]. In these cases, otherrestrictions and levels than those referenced above may be used.Other standards may apply to equipment covered by this standard. In particular this standard can notbe used to demonstrate electromagnetic compatibility with other equipment; nor does it specify anyproduct safety requirements other than those specifically related to human exposure toelectromagnetic fields.The frequency range covered is 0 Hz to 300 GHz.NOTE 2 Procedures to demonstrate conformity are not specified for the whole frequency range.
