This European Standard provides a procedure to assess the risk to workers bearing one or more active implantable medical devices from exposure to electric, magnetic and electromagnetic fields at a workplace. It describes how a general risk assessment should be performed and determines whether it is necessary to carry out a detailed risk assessment.NOTE 1This European Standard does not cover indirect effects caused by non active implants.NOTE 2The risk of human exposure to EMF considered is only due to malfunctioning of AIMD. Possibilities of AIMD contribution to the risk, e.g. local modification of the distribution of EMF produced by external source or production of own EMF, are covered by the respective product standards for the AIMD.Based on specific workplace standards it can be determined whether preventive measures/actions need to be taken to comply with the provisions of Directive 2013/35/EU. The work situation covered is considered to be under normal working conditions including normal operation, maintenance, cleaning and other situations being part of the normal work.The frequencies covered are from 0 Hz to 300 GHz.The European Parliament and Council Directive 2013/35/EU will be transposed into national legislation in all the EU member countries. It is recommended that users of this standard consult the national legislation related to this transposition in order to identify the national regulations and requirements. These national regulations and requirements may have additional requirements that are not covered by this standard and take precedence.NOTE 3Performance requirements with respect to active implantable medical devices are excluded from the Scope of this standard. These are defined in the relevant particular standards for active implantable medical devices.The risk assessment described in this standard is only required if an AIMD-Employee is present.Active Implantable Medical Devices (AIMDs) are regulated by Directive 90/385/EEC and the amendments to it.NOTE 4Product standards EN 45502-1 and of the EN 45502-2-X series describe the product requirements for different kinds of AIMDs. Different kinds of AIMDs are e.g. pacemaker (EN 45502-2-1), implantable cardioverter defibrillators (EN 45502-2-2), cochlear implants (EN 45502-2-3), implantable neurostimulators (ISO 14708-3), implantable infusion pumps (ISO 14708-4).In situations where the risk assessment following this standard does not lead to a conclusion, complementary provisions for the assessment of workers exposure for different kinds of AIMDs are given in particular standards for these specific AIMDs (see Figure 1).(...)Figure 1 - Structure of the EN 50527 family of standards
