Application Note As of January 1, 1996, all electrical or electronics products shipped into the European Union that could either cause electromagnetic interference (EMI) or could be susceptible to EMI, must be tested to ensure adherence to the EMC Directive. (If a manufacturer believes that a product does not cause EMI and is not affected by EMI, the onus is on the manufacturer to substantiate his claims.) In order to comply with the EMC Directive, the following products listed must conform to applicable Product or Product Family Standards. If no Product or Product Family Standards exist, the product must comply with the Generic Immunity and Emissions standards. These generic standards are divided into two areas:
Residential, Commercial and Light-Industrial Environments EN 50081-1, the generic emission standard for residential, commercial and light industrial states that:"The environments encompassed by this standard are residential, commercial and light-industrial locations, both indoor and outdoor. The following list, although not comprehensive, gives an indication of locations, which are included: - residential properties, e.g. houses, apartments - retail outlets, e.g. shops, supermarkets - business premises, e.g. offices, banks - areas of public entertainment, e.g. cinemas, public bars, dance halls - outdoor locations, e.g. petrol stations, car parks, amusement and sports centres - light-industrial locations, e.g. workshops, laboratories, service centres Locations which are characterized by being supplied directly at low voltage from the public mains network are considered to be residential, commercial or light industrial." Industrial Environment EN 50081-2, the generic emission standard for the industrial environment states that: "Apparatus covered by this standard is not intended for connection to the public mains network but is intended to be connected to a power network supplied from a high or medium-voltage transformer dedicated for the supply of an installation feeding manufacturing or similar plant." Industrial locations are characterized by the existence of one or more of the following conditions: - industrial, scientific and medical (ISM) apparatus - heavy inductive or capacitive loads are frequently switched - currents and associated magnetic fields are high These are the major contributors to the industrial electromagnetic environment and as such distinguish the industrial from other environments. ISM equipment is defined in EN 55011, Annex A as: ". suitable for use in all establishments other than domestic and those connected to a low voltage power supply network which supplies buildings used for domestic purposes." Some examples from Appendix A of EN 55011 for ISM equipment include: signal generators, measuring receivers, spectrum analyzers, chemical analysis machines and switched mode power supplies. Examples of general equipment include: industrial induction heating equipment, industrial microwave heating equipment, medical apparatus (specifically short-wave therapy equipment and microwave therapy equipment), spark erosion equipment, and spot welders. Some overlap exists in the definitions of the two categories and it is up to the manufacturer to use the best judgement in selecting the appropriate category. The manufacturer always has the final responsibility in assuring compliance with the directive. |
