Introduction
ETSI TR 100 027 [i.1] written in the early days of ETSI, provides a set of methods of measurement for private mobile
radio equipment to be used as draft material in ETSI standards written at a later stage. The original intention was to
keep it up to date but that work was never done. Later on other documents addressing methods of measurements were
developed (ETSI TR 102 273 [i.2] to [i.9], ETSI TS 103 052 [i.11]). Some ERM WGs have in addition developed their
own documents (e.g. ETSI EN 300 220-1 [i.29] in TG28, ETSI EN 303 883 parts 1 [i.30] and 2 [i.31] in TGUWB).
There is not one clear reference measurement procedures available for rapporteurs of radio standards with the risk that
radio standards in ETSI will diverge in different directions.
ETSI
5 ETSI TR 103 773 V1.1.1 (2022-01)
The present document aims to analyse the ways in which a set of reference documents (e.g. a set of technical
specifications) could be written including text for methods of measurement to be used as reference material in future
ETSI standards. The present document analyses if there is a clear benefit of developing and maintaining such reference
documents, for which areas reference documents should be developed at a central place in ETSI (e.g. at WGRM), for
which areas the expert WG should be responsible, and if there would be other options (e.g. refer to existing documents
from other organizations.). Pros and cons of different options are analysed. Such reference documents would provide a
clear guidance on common information and methods in harmonised standards and it would be a huge help for
rapporteurs of new harmonised standards. The aim of the present document is to describe the various possibilities and
find out their different merits.
The present document is structured as follows:
• Clause 1 provides the scope
• Clause 2 provides a list of used normative and informative references
• Clause 3 provides the definition of terms, symbols and abbreviations used in the present document
• Clause 4 provides an overview of available ETSI guidance for rapporteurs of harmonised standards
• Clause 5 provides related information on requirements and definitions
• Clause 6 provides a discussion on the need of a method of measurement
• Clause 7 provides a discussion of the pros and cons of the different options
• Clause 8 provides a conclusion

4 Available ETSI guidance for rapporteurs of
harmonised standards
Before starting with the analysis on how to develop reference documents for methods of measurements for radio
standards in ETSI, the document does first provide an overview of the status quo.
Harmonised standards are developed within the relevant ERM working group under the leadership of the rapporteur of
the standard.
The rapporteurs are guided by the ETSI Drafting Rules, which is provided in the ETSI Directives [i.17].
The ETSI Drafting Rules do first refer to a pre-structured deliverable skeleton [i.22] which is used as a basis for
drafting. The skeleton for harmonised standard is maintained by the ETSI secretariat and provides partly technical
guidance relevant for measurements procedures, e.g.:
• example text for the environmental profile clause(s) of harmonised standards;
• example text on measurement uncertainty.
The ETSI drafting rules do also define the objective of an ETSI deliverable as "to define clear and unambiguous
provisions in order to facilitate international and European trade and communication". To achieve this objective, an
ETSI deliverable should:
• "be as complete as necessary within the limits specified by its scope;
• be consistent, clear and accurate;
• provide a framework for future technological development;
• be comprehensible to qualified persons who have not participated in its preparation; and
ETSI
11 ETSI TR 103 773 V1.1.1 (2022-01)
• respect the rules for the drafting of ETSI deliverables."
The ETSI Drafting Rules [i.17] has in clause 8.1 the following general guidance on conformance tests for harmonised
standards:
• "the HS shall include all technical specifications necessary for demonstrating presumption of conformity of the
products and phenomena within its scope;"
Further general guidance on conformance tests in harmonised standards is provided in clause 7.2 of ETSI
EG 203 336 [i.18]:
• "Where technical parameters are specified, these should be accompanied by a test/assessment method, related
to the required limits and pass/fail criteria. The shared risk approach, which aims to equally share the risks of
allowing equipment failing a limit and rejecting equipment that complies with a limit, is standard practice in
ETSI HSs. Where the TB decides to include measurement uncertainty in an HS it should not be within a
normative part of the HS."
In addition the ETSI harmonised standard checklist [i.26] provides the following guidance:
• "Harmonised standards should report precise, complete, well defined and clear performance criteria,
technical specifications and test methods to provide presumption of conformity. If deemed appropriate, the
harmonised standard can define different precise performance criteria, technical specifications and test
methods for different (sub)categories or (sub)classes of radio equipment."
In addition to the above generic guidance, the common technical content of harmonised standards (e.g. methods of
measurements) has been standardized in several generic documents to support the rapporteurs (see Table 1). Table 1
provides a non-exhaustive list of published ETSI reference documents.

5 Requirements and definition of terms
Connected to each method of measurement is a requirements, which is ideally defined at a central place. The definition
of terms used in ETSI standards are summarized in ETSI TR 103 265 [i.21] and in the TEDDI database [i.20]. At the
time of writing the present document the definition of terms in published ETSI standards were not aligned between all
ETSI standards.
To improve the situation, a new work is planned to develop preferred and common definition of terms for harmonised
standards. The aim is to align the definition of terms in ETSI standards.
Generally a harmonised standard should not create its own terms if the parameters are already defined at a higher level,
e.g. in the EC Directives, EC Decisions, CEPT/ECC documents, ITU-R documents, Radio Regulations. Another useful
source for definitions is the IEC International Electrotechnical Vocabulary [i.19].
6 The need of a method of measurement
Is a method of measurement needed as a normative part in a harmonised standard to proof the compliance against a
requirement or is method of measurement redundant? Three theoretical cases are possible:
• Case A: A standard says nothing and everything is left to the interpretation of the manufacturer (risk
assessment)
• Case B: A standard provides a common method of measurement which ensures a common quality (state of the
art)
• Case C: A standard provides every detail
ETSI
15 ETSI TR 103 773 V1.1.1 (2022-01)
As a first step the value of a harmonised standard only with requirements but without measurement procedures is
discussed in the following (Case A):
• such a standard would not provide a standardized methods of measurement;
• the manufacturer would need to proof in its technical documentation and risk assessment how the equipment
complies with the requirements without a standardized guidance;
• in absence of a harmonised method of measurement, the quality of the assessment of the manufacturers (with
and without measurements) would very likely be very different; and
• the quality of the assessment would also depend on the quality of the definition of the requirements (e.g. in the
regulation), and in many cases the regulation is not absolutely clear; for this reason one main objective of
standardization is to support/complement the regulation);
• national frequency assignments do usually refer to a harmonised standards, to clarify how a limit should be
measured; without a method of measurement such a reference would be not present.
In addition, the ETSI drafting rules [i.17] and the ETSI EG 203 336 [i.18] do ask for a method of measurement to be
used (see more details in clause 4).
As a consequence a harmonised standard should, if possible, contain guidance on how to perform a measurement to test
compliance towards parameters given in regulation and mutual agreements achieved in ETSI (not being regulation).
However, it is important to note that for some parts of a method of measurement it is more important to provide a
detailed description than for others; test hardware and test setup description may require more details than the
description of the test process (e.g. test frequencies, angular resolution of antenna measurements). Further information
on the detail degree of a method of measurement is provided in Annex A. It should also be noted that standardization is
an iterative process, where shortcomings in a published standard are reported to ETSI which triggers a new work item
to improve the standard.
Also the RED [i.16] foresees a procedure for market surveillance authorities for radio equipment presenting a risk at
national level (Directive 2014/53/EU [i.16] article 40 and 41), which can lead to the withdrawal of the references to the
harmonised standard concerned from the Official Journal of the European Union (Regulation (EU) No 1025/2012 [i.15]
article 11 on "Formal objections to harmonised standards").
The above conclusion that a method of measurement should (if possible) be part of a harmonised standard, is drawn
under the assumption that the method of measurement is feasible. They apply to typical regulatory requirements like
radiated power, unwanted emissions, receiver requirements. But there are (regulatory) requirements where a method of
measurement procedure is not possible or is meaningless:
• Duty cycle limit in regulation for equipment where the duty cycle of the equipment is dependent on the use
(e.g. garage door opener).
• Push-button, Wall contact (ETSI EN 302 065-4-1 [i.44]).
• Dimension of boundary wire of a lawn mower (ETSI EN 303 447 [i.45]).
• Applying requirements over temperature range.
Such requirements do typically apply to the user of the equipment or to the installer of a network and they cannot be
tested when putting the device to the market. One approach could be to outlaw such requirements in the scope clause
but this requires the manufacturer to declare the applicability of this.
7 Discussion
7.1 Summary previous clauses
Guidance for rapporteurs of harmonised standard is available in a huge number of ETSI documents (see clauses 4 and
5). However due to the huge number of documents, the variety of possible methods of measurement is also huge and
there is a diverse use of terms and definitions.
ETSI
16 ETSI TR 103 773 V1.1.1 (2022-01)
The need of a method of measurement was discussed in clause 6 and it was concluded that in most cases it is needed.
But there are cases where a method of measurement is not possible or meaningless.
7.2 Options to proceed
Are the documents from ETSI now sufficient to support the work of rapporteurs or should ETSI start developing and
maintaining reference documents?
Numerous ETSI reference documents are available but they are not maintained at a central place. A clear reference
document would be better which should be maintained by ETSI. There is agreement to as much as possible use
standardized methods of measurement (including test equipmen
