CE Low Voltage Directive (LVD)
Low voltage directive of European Community is 2006/95/EC. The directive applies to devices using alternating current (AC) 50-1,000V and direct current (DC) 75-1,500V.
The directive describes list of exempted devices on its Annex II.
- Electrical equipment for use in an explosive atmosphere
- Electrical equipment for radiology and medical purposes
- Electrical parts for goods and passenger lifts
- Electricity meters
- Plugs and socket outlets for domestic use
- Electric fence controllers
- Radio-electrical interference
- Specialized electrical equipment, for use on ships, aircraft, or railways, which complies with the safety provisions drawn up by international bodies in which the Member States participate.
CE Electro Magnetic Compatibility Directive (EMC)
The main goals of the directive 2004/108/EC are to
- ensure that the electromagnetic disturbances produced by equipment does not affect the correct functioning of other apparatus as well as radio and telecommunications networks, related equipment, and electricity distribution networks; and
- to ensure that equipment has an adequate level of intrinsic immunity to electromagnetic disturbances to enable them to operate as intended.
Compliance to EMC directive means the device satisfies acceptable criteria for
- level of emitted electromagnetic interference
- immunity to electromagnetic interference
‘Electromagnetic disturbance’ means any electromagnetic phenomenon which may degrade the performance of equipment. Examples are
- Electromagnetic noise
- Unwanted signal; or
- Change in the propagation medium
EMC directive does not apply to below devices.
- Military equipment
- Supplies for vehicle and/or truck
- Medical devices including Active implantable medical devices and in-vitro medical devices
Below devices are subject to ECM directive.
- Radio, TV, transmitters, and telephone
- Battery-operated device
- Electric fuse
- Capacitors, resistors, and other electrical parts
- Home appliances
- Battery charger
- Power supply
- Computers, printers
It is not mandatory to have CoC(Certification of Conformity) from third party (certification body). The manufacturer may draw DoC (Declaration of Conformity) and distribute the device.
In order to draw DoC, it is necessary to have complete technical construction file of the device in question. A test report, issued by approved testing lab, shall be included in TCF as a proof of compliance to the directive. Once the technical document is complete, a representative of the organization shall print name, date, and sign the DoC. Some nations may request for CoC issued by a certification body.
