This includes the CE marking for after market ESAs described in category a) above, but additionally requires that the limits of the clauses referenced in Annex 1, clause 3.2.9 of the Automotive EMC Directive are fulfilled.

The Automotive EMC Directive recognizes conformity according to the procedures of the EMC Directive and the Radio Equipment Directive (RED). As a general rule these are ESAs which are not related to an immunity-related function of the motor vehicle, are connected directly to the vehicle's dc supply, and are not involved/related with any of the vehicle functions (described in Annex 1, clause 2.1.12 of the Directive).ī) After market equipment intended for installation in a motor vehicle, and which is related to immunity related functions of the motor vehicle, as set out in Annex 1, clause 2.1.12 of the Directive, is subject to full type approval requirements of the Directive. The Directive covers two categories of after market equipment ESAs:Ī) After market equipment intended for installation in a motor vehicle, and which are not related to immunity related functions of the motor vehicle. The annexes of this Directive contain all the technical requirements necessary to demonstrate conformance which allows the ESA to be placed on the market. These requirements are set out in Directive 2004/104/EC, a specific Directive which forms part of European legislation for automotive type approval. Alternatively, manufacturers may choose to request certification of equipment by a recognized third party, known as a 'Notified Body'.Įlectrical equipment (including telecommunications equipment) intended to be fitted to a motor vehicle are considered to be 'Electronic Sub Assemblies (ESA)' and are required to meet Automotive EMC requirements.

the apparatus has an adequate level of intrinsic immunity to electromagnetic disturbance to enable it to operate as intended.Įquipment which meets Harmonised Standards is presumed to comply with the essential requirements, and a manufacturer may declare conformity with the Directive.

the electromagnetic disturbance it generates does not exceed a level allowing radio and telecommunications equipment and other apparatus to operate as intended and.

In the case of the EMC Directive, the essential requirements are that equipment shall be designed and manufactured such that: Harmonised Standards define technical characteristics which can be used to demonstrate compliance with the essential requirements of the Directive. As such, they rely for their operation on Harmonised Standards developed by recognized European standards bodies, such as ETSI.

The EMC Directive and many of the other relevant Directives are 'New Approach' Directives. Amateur radio equipment not available commercially.Medical devices, including implantable devices.Equipment covered by the Radio Equipment Directive (RED).However, there are many types of equipment that are excluded from the EMC Directive, although EMC requirements for most of them are included in other Directives and regulations. Within Europe, EMC regulation is managed mainly through the European Commission's EMC Directive (2014/30/EU) and for Radio equipment through Directive 2014/53/EU. EMC regulationĪs the effects of interference have severe consequences, EMC is frequently a subject of national and international regulation.

It is part of the EMC 'art' to design and operate equipment so that it is both prevented from emitting spurious energy that can cause interference and is immune to the adverse effects of any spurious energy that it may receive. Obviously, radio transmitters and receivers are intended to emit and receive electrical energy, but other equipment may not be intended to do so.Įven transmitters and receivers may emit and receive unwanted energy that may prevent those devices, or others, from functioning as intended. Equally, equipment may be susceptible to receiving energy emitted from other sources. All such equipment emits electrical energy, and some of that emitted energy may interact and interfere with other equipment. ElectroMagnetic Compatibility (EMC) is a characteristic of electrical and electronic equipment that permits it to operate as intended in the presence of other electrical and electronic equipment, and not to adversely interfere with that other equipment.
