Foreword
This European Standard (Telecommunications series) has been produced by ETSI Technical Committee
Electromagnetic compatibility and Radio spectrum Matters (ERM).
For non EU countries the present document may be used for regulatory (Type Approval) purposes.
The present document is part 1 of a multi-part deliverable covering the Electromagnetic compatibility and Radio
spectrum Matters (ERM); Short Range Devices (SRD); Radio equipment in the frequency range 9 kHz to 25 MHz and
inductive loop systems in the frequency range 9 kHz to 30 MHz, as identified below.
Additionally, the present document should be read in conjunction with CEPT/ERC/Recommendation 70-03 [3] together
with the respective ECC Decisions as implemented through National Radio Interfaces (NRI) and additional NRI as
relevant. The Recommendation states the recommended transmitter parameters for the various SRD applications in the
appropriate annexes.
The content of the standard is:
Part 1: "Technical characteristics and test methods";
Part 2: "Harmonized EN under article 3.2 of the R&TTE Directive".

1 Scope
The present document applies to Short Range Devices (SRDs) transmitters and receivers:
• transmitters operating in the range from 9 kHz to 25 MHz; and
• inductive loop transmitters operating from 9 kHz to 30 MHz;
• receivers operating from 9 kHz to 30 MHz.
The present document does not necessarily include all the characteristics which may be required by a user, nor does it
necessarily represent the optimum performance achievable. It is a product family standard which may be completely or
partially superseded by specific standards covering specific applications.
The present document applies to generic SRDs including:
• inductive loop systems;
• systems with an antenna connector and/or an integral antenna;
• systems for alarm, identification, telecommand, telemetry, etc.; and/or
• applications with or without speech.
When selecting parameters for new SRDs, which may have inherent safety of human life implications, manufacturers
and users should pay particular attention to the potential for interference from other systems operating in the same or
adjacent bands.
The present document covers fixed stations, mobile stations and portable stations. If a system includes transponders,
these are measured together with the transmitter.
All types of modulation for radio devices are covered by the present document, provided the requirements of clause 7.3
are met.
The radio equipment, covered by the classification SRD is divided into several classes based on the maximum radiated
magnetic field strength. The field strength designation in the present document is based on
CEPT/ERC/Recommendation 70-03 [3] and National SRD-frequency designations.
Three types of measuring methods are defined in the present document due to the varied nature of the antenna types for
equipment used in this band. One method measures the RF carrier current, another measures the radiated H-field and
the third the conducted power.
The present document covers requirements for radiated emissions below as well as above 30 MHz.
Additional standards or specifications may be required for equipment such as that intended for connection to the
Public Switched Telephone Network (PSTN).

4 Technical requirements specifications
4.1 General requirements
4.1.1 Receiver classification
The product family of short range radio devices is divided into three receiver Classes, see table 1, each having its own
set of minimum performance criteria. This classification is based upon the impact on persons in case the equipment
does not operate above the specified minimum performance level.
Table 1
Receiver class Relevant receiver clauses Risk assessment of receiver performance
Safety critical SRD communication media; i.e. for devices serving
1 8.1, 8.2 and 8.3
systems where failure may result in a physical risk to a person.
Function critical SRD communication media; i.e. when a failure to
2 8.2 and 8.3 operate correctly causes loss of function but does not constitute a
safety hazard.
Non-critical SRD communication media whose failure to operate
3 8.3 correctly causes loss of function which can be overcome by
parallel means.
NOTE: With reference to the present document manufacturers are recommended to declare classification of
their devices in accordance with table 1, as relevant. In particular where an SRD which may have an
inherent safety of human life implication, manufacturers and users should pay particular attention to the
potential for interference from other systems operating in the same or adjacent bands.
