Foreword
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
under Council Directive 98/34/EC [3] laying down a procedure for the provision of information in the field of technical
standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Directive 1999/5/EC [1] of the European Parliament and
of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual
recognition of their conformity ("the R&TTE Directive").
The present document is part 2 of a multi-part deliverable, covering digitally modulated Radiosonde transmitters in the
Meteorological Aids frequency band from 400,15 MHz to 406 MHz, as identified below:
Part 1: "Technical characteristics and test methods";
Part 2: "Harmonized EN covering essential requirements under article 3.2 of the R&TTE Directive".
Technical specifications relevant to Directive 1999/5/EC [1] are given in annex A.

National transposition dates
Date of adoption of this EN: 14 March 2003
Date of latest announcement of this EN (doa): 30 June 2003
Date of latest publication of new National Standard
or endorsement of this EN (dop/e): 31 December 2003
Date of withdrawal of any conflicting National Standard (dow): 30 June 2006

Introduction
The present document is part of a set of standards designed to fit in a modular structure to cover all radio and
telecommunications terminal equipment under the R&TTE Directive [1]. Each standard is a module in the structure.
The modular structure is shown in figure 1.

The left hand edge of the figure 1 shows the different clauses of article 3 of the R&TTE Directive [1].
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 figure 1 shows EN 301 489 [6], the multi-part product EMC standard for radio used under the EMC
Directive [7].
For article 3.1a figure 1 shows the existing safety standards currently used under the LV Directive [5] and new
standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be
required.
The bottom of figure 1 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 [1] 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 [1] 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.
