European common framework for the
marketing of products (CE Mark)
The CE Mark (("Conformité
Conformité Européenne
Européenne", "European
European Conformity
Conformity")), existing in its present form since
1993, is a mandatory conformance mark on many products placed on the market in the European
Economic Area (EEA).
The EC directives for CE marking include the following groups:
• ElectroMagnetic Compatibility;
• Low Voltage;
• Medical Devices;
• Radio and Telecommunications Terminal Equipment;
• Safety of Toys;
• etc….

d
electronic appliances, systems and installations.

electromagnetic disturbances and its normal operation is not affected by such disturbances. Hence,
equipment without electrical and/or electronic parts (inherently benign equipment) is not in the
scope of the EMC Directive, such as simple domestic heaters with no controls, thermostat, or fan;
headphones,
headphones loudspeakers without amplification; pocket lamps without active electronic circuits
and etc.
EMC Directive explicitly excludes three types of equipment:
- Radio equipment and telecommunications terminal equipment covered by R&TTE Directive
- Aeronautical products, parts and appliances
- Equipment covered by other specific Community Directives, such as Motor Vehicles (Directive
72/245/EEC and 2004/104/EC), Medical Devices (Directive 93/42/EEC), Marine Equipment
(Directive 96/98/EC) and etc.

New EMC Directive
2014/30/EU
 The new EMC Directive* (2014/30/EU) has already become effective as published in
the Official Journal of the European Union dated 29 March 2014, and as stated in
Article 46 of the Directive
 The existing Directive 2004/108/EC ceases to be applicable as from 20 April 2016
 A significant change is that there should only be a single EU Declaration of
Conformity
to ensure
y (DOC)
(
) in respect
p of all Union acts,, applicable/required
pp
q
conformity with the requirements for CE-marking. Information of the manufacturer
and the product, and the DOC, must be in language easily understood by the
destination’s end-users and required by the Member State’s authorities
 There are many
man other new
ne and tough
to gh requirements,
req irements e.g.
eg
1. Manufacturer is part of the Economic Operators, and therefore shall ensure that their products "have been
designed and manufactured in accordance with the essential requirements". (Article 7)
2. In the existing Directive, responsibility lies with "the person who places the products on the Community
market",

bu now
ow thee new
ew Directive
ec ve states:
s es: "thee manufacturer

3. Increased control on the competence of Notified Body (Article 31), and inferior Notified Body's service may
be unable to be "pan-European" anymore. (Preamble 45)
4. There is a "Union Safeguard Procedure" that „.. all Member States shall take the necessary measures to
ensure that the non-compliant
non compliant apparatus is withdrawn from their market“ (Article 39)
5. As said in the Preamble (37), "one of the conformity assessment procedures requires the intervention of
conformity assessment bodies, which are notified by the Member States to the Commission“, this implies the
using of NB for an "EC-type examination certificate" is encouraged in the Directive as "Module B": (Annex III
Part A).
6.
After using NB, manufacturer can specify the name and ID number of the NB in the
"Declaration of Conformity (DOC) " (Annex IV).

Emissions and Immunity
 Any EM noise emission
emission, ‘natural’
natural or ‘man
man-made
made’, is potentially a disturbance to any other susceptible
device in the environment. It may either put it out of action or, in many cases a worse problem, cause
it to malfunction. So there are two sides to the EMC equation:
 source equipment whose controllable emissions must be limited; and
 equipment needs to have adequate immunity to those disturbances in its environment to which
it is exposed.
 EM disturbances may work in more than one direction, disrupting more than one device, or multiple
sources may have a cumulative effect on a single piece of equipment. Thus an air traffic control radar
may affect the display of a laptop computer being used in an aircraft as well as other vital devices in
use on the ground
ground. At the same time
time, emissions from the same laptop computer may combine with
those from a mobile phone to disturb systems in the aircraft.
 On the emissions side of the equation, therefore, the aim of EMC is to ensure that equipment does not
disturb other equipment, radio services, power or other networks. On the immunity side, the aim is to
ensure that equipment is not affected by, e.g., radio transmissions, mains-borne disturbances,
electrostatic fields and other phenomena.
