SIST EN 302 609 V1.1.1:2009 is the Slovene adoption of ETSI EN 302 609 V1.1.1, a Harmonized European Standard for Euroloop railway radio equipment. It specifies radio spectrum and electromagnetic compatibility requirements, test conditions, and measurement methods for the On-Board Equipment (OBE) and the Track-Side Equipment used in Euroloop transmission systems. The standard supports article 3.2 of the R&TTE Directive, so it is used to show that the equipment uses spectrum effectively and avoids harmful interference.
What does SIST EN 302 609 V1.1.1:2009 specify?
SIST EN 302 609 V1.1.1:2009 covers the technical requirements for radio transmitters and receivers used in the Euroloop transmission system in railway applications. It applies to two equipment units: the OBE, which receives the Euroloop signal, and the track-side Euroloop unit, which transmits the signal from the rail area.
The document is organized into clauses for scope, references, definitions, technical requirements, test conditions, measurement uncertainty, and test procedures. The annexes then connect the requirements to conformance testing and give supporting measurement methods.
| Annex | What it covers |
|---|---|
| Annex A | HS Requirements and conformance Test specifications Table linking requirements to test clauses |
| Annex C | Radiated measurement |
| Annex D | Field strength measurements along the Euroloop |
| Annex E | E-fields in the near field at low frequencies |
| Annex F | H-field measurements and limits at 3 m and 30 m |
What are the key requirements of SIST EN 302 609 V1.1.1:2009?
SIST EN 302 609 V1.1.1:2009 defines three essential radio test areas: unwanted emissions from the OBE, magnetic field strength from the Euroloop installation, and the Euroloop transmitter spectrum mask. In practice, these are the checks that show whether the equipment can operate in the railway environment without causing unacceptable interference.
OBE unwanted emissions
Clause 4.1 applies only to the OBE. The OBE is checked for unwanted emissions with radiated measurement below 30 MHz and conducted measurement from 30 MHz to 1 000 MHz.
For a manufacturer, this means the receiver unit must be verified not to radiate or conduct spurious energy above the stated limits. For a test lab, it means using the correct split between radiated and conducted methods and recording the results against the limit.
Euroloop field strength
Clause 4.2 applies only to the Euroloop transmitter. The transmitted magnetic field strength is measured radiated in the railway environment, with results assessed over the installed loop length.
This matters because the track-side unit is part of the railway infrastructure, not a bench-top transmitter. The test shows whether the installed system stays within the permitted field strength across the relevant section of track.
Euroloop transmitter mask
Clause 4.3 applies only to Euroloop transmitters and is checked by conducted measurement. The transmitter spectrum must follow the specified mask, which controls the allowed spectral shape and out-of-band behavior.
In practice, this is the lab check that the transmitter output is spectrally well behaved before installation. It helps confirm that the transmitter does not occupy or spill into frequencies outside its intended operation.
Test conditions and test setup
Clause 5 sets the test conditions, including normal temperature and humidity, the test power source, and the Euroloop test modulation. The applied DSSS code is the Euroloop test-code #15 from SUBSET-044, and the manufacturer must provide means to operate the transmitter during testing.
This matters because test results need to be repeatable and representative. It also tells the supplier what sample, power source, and operating mode the laboratory needs.
Equipment selection and uncertainty
Clause 5.5 says tests are carried out on production or equivalent preliminary models, and that optional features affecting RF parameters are tested in the worst-case configuration. Clause 6 requires measurement uncertainty to be reported and linked to the measured value used for compliance decisions.
For buyers and auditors, this is the evidence trail: which model was tested, how it was configured, and how uncertainty was handled. For labs, it means the report must show the uncertainty alongside the measurement result.
Measurement methods
Clause 7 gives the essential radio test suites for OBE unwanted emissions, Euroloop transmitter conducted measurements, and Euroloop field strength measurements. Annexes D, E, and F provide the calculation and conversion methods used when measurements are taken along the loop or at alternative distances.
What terms does SIST EN 302 609 V1.1.1:2009 define?
- dedicated antenna - A removable antenna supplied and tested with the radio equipment as an integral part of the system.
- euroloop - The wayside transmission unit that uses magnetic transmission technology to communicate with a passing train.
- magnetic transmission technology - A method that uses magnetic coupling in the air gap between transmitter and receiver.
- rf carrier - The fixed radio frequency before modulation.
- uplink - The transmission link from the Euroloop to the OBE.
- BPSK - Binary Phase Shift Keying, the modulation used for the Euroloop transmit signal.
- DSSS - Direct Sequence Spread Spectrum, the spread-spectrum method used in the Euroloop transmitter.
- OBE - On-Board Equipment, the train-mounted unit that receives the Euroloop signal.
Who uses SIST EN 302 609 V1.1.1:2009?
This standard is used by manufacturers of Euroloop OBE and track-side equipment, railway signalling suppliers, and test laboratories. It is also relevant to conformity assessment bodies, system integrators, and railway buyers who need a clear test basis for RF performance and interference control.
In practice, they use it to design the equipment, select a test configuration, run emissions and field-strength tests, and prepare technical documentation and test reports. For procurement, it helps define what evidence a supplier should provide for Euroloop radio equipment intended for railway use.
Which standards are used with SIST EN 302 609 V1.1.1:2009?
- ETSI TR 100 028 - Used for calculating measurement uncertainty for the test methods in this standard.
- ERTMS/ETCS - CLASS 1, SUBSET-044 FFFIS for Euroloop - Provides the Euroloop test-code and operating specification used during testing.
- ETSI TR 102 273 - Gives additional information on radiated methods of measurement and uncertainty.
- ETSI EN 302 608 - The related harmonized EN for Eurobalise railway systems, referenced for the Eurobalise OBE transmitter mask.
What does the SIST EN 302 609 V1.1.1:2009 document contain?
The document contains the testable RF requirements, the test conditions, the uncertainty rules, and the detailed measurement procedures used for Euroloop equipment. Annex A ties each requirement to its test clause for conformance work, while clause 7 gives the step-by-step test suites.
It also includes supporting methods for radiated measurement, field-strength evaluation along the loop, near-field conversion, and alternative measurement-distance conversion. Annex D provides the processing method for combining field components and extracting a representative loop envelope, and Annex F gives the distance conversion approach for 3 m and 30 m cases.
The document therefore serves as a practical conformance reference for design verification, laboratory testing, and technical file preparation for railway Euroloop radio equipment.

ETSI standards Two-step Approval Procedure.
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [i.5] (as amended) 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 [i.6] 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").
Technical specifications relevant to Directive 1999/5/EC [i.6] are given in annex A.
The Euroloop transmission system operates in accordance with ERC Recommendation 70-03, annex 4.
These specifications are complementary with the system and interoperability requirements for these devices established
under Commission Decision 2004/447/EC [i.7].
