This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical
Committee Electromagnetic compatibility and Radio spectrum Matters (ERM).The present document has been produced by ETSI in response to a mandate from the European Commission issued

The left hand edge of figure 0.1 shows the different clauses of article 3 of the R&TTE Directive [2].
For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of the present
document essential requirements in these areas have to be adopted by the Commission. If such essential requirements
are adopted, and as far and as long as they are applicable, they will justify individual standards whose scope is likely to
be specified by function or interface type.The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The
scopes of these standards are specified either by frequency (normally in the case where frequency bands are
harmonized) or by radio equipment type.For article 3.1b the diagram shows EN 301 489, the multi-part product EMC standard for radio used under the
EMC Directive [3].For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [4] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
required.The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal
equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio
spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant
essential requirement under the R&TTE Directive is adopted by the Commission and if the equipment in question is
covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential
requirements under the R&TTE Directive may be covered in a set of standards.The modularity principle has been taken because:
• it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and
functions it is not practicable to produce a single standard for each possible combination of functions that may
occur in an equipment;• it provides scope for standards to be added:
- under article 3.2 when new frequency bands are agreed; or
- under article 3.3 should the Commission take the necessary decisions
without requiring alteration of standards that are already published;
• it clarifies, simplifies and promotes the usage of Harmonized Standards as the relevant means of conformity
assessment.Other documents directly associated with the present document:
• EN 302 018-1 [5];
• EN 301 489-11 [6].

3.1 Definitions
For the purposes of the present document, the following terms and definitions apply:
antenna port: port of an apparatus which is designed, in normal operation, to be connected to an antenna using coaxial
cablebroadcasting service: radio communication service in which the transmissions are intended for direct reception by the
general publicNOTE: This service may include sound transmissions, television transmissions or other types of transmission.
cabinet radiation: radiation from an enclosure containing, equipment, excluding radiation from connected antennas or
cablescarrier power: average power supplied to the antenna transmission line by a transmitter during one cycle taken under
the condition of no modulationchannel L: left hand channel of a stereophonic signal
channel R: right hand channel of a stereophonic signal
class of emission: set of characteristics of an emission, designated by standard symbols, e.g. type of modulation of the
main carrier, modulating signal, type of information to be transmitted, and also, if appropriate, any additional signal
characteristicscomposite: See "Multiplex (MPX) signal".
dBc: decibels relative to the unmodulated carrier power of the emission
NOTE: In the cases which do not have a carrier, for example in some digital modulation schemes where the
carrier is not accessible for measurement, the reference level equivalent to dBc is decibels relative to the
mean power P.difference signal: signal (S) theoretically equal to half the difference between the left (L) and right (R) stereophonic
signals, and in practice proportional to this difference. S = (L - R) / 2enclosure port: physical boundary of the apparatus through which electromagnetic fields may radiate or impinge
NOTE: In the case of integral antenna equipment, this port is inseparable from the antenna port.
environmental profile: range of environmental conditions under which equipment within the scope of EN 302 018-2 is
required to comply with the provisions of EN 302 018-2exclusion band: band of radio frequencies where no measurements are made
harmonic: component of order greater than 1 of the Fourier series of a periodic quantity
harmonic number: integral number given by the ratio of the frequency of a harmonic to the fundamental frequency
