SIST EN 301 178-2 V1.2.2:2007 is the Slovenian adoption of ETSI EN 301 178-2 V1.2.2 (2007-02). It is a harmonized European Standard for portable Very High Frequency (VHF) radiotelephone equipment used in the maritime mobile service on VHF bands for non-GMDSS applications only. The document specifies the minimum technical characteristics and measurement methods used to show that this equipment uses spectrum effectively and avoids harmful interference under Article 3.2 of the R&TTE Directive.

What does SIST EN 301 178-2 V1.2.2:2007 specify?

SIST EN 301 178-2 V1.2.2:2007 specifies the radio-performance requirements and conformance tests for portable VHF radiotelephones that are not part of the Global Maritime Distress and Safety System (GMDSS). It covers equipment operating in maritime mobile service frequency bands and using both 25 kHz and 12,5 kHz channels.

The document is organized into five clauses plus three annexes:

• Clause 1 - Scope
• Clause 2 - References
• Clause 3 - Definitions and abbreviations
• Clause 4 - Technical requirements specifications
• Clause 5 - Testing for compliance with technical requirements

Annex	What it covers
Annex A	HS Requirement and conformance Test specifications Table (HS-RTT) for presumption of conformity
Annex B	The EN title in the official languages
Annex C	Bibliography

The foreword also places this part in a two-part deliverable. Part 1 is the companion document for technical characteristics and methods of measurement, and Part 2 is the harmonized EN for Article 3.2 of the R&TTE Directive.

What are the key requirements of SIST EN 301 178-2 V1.2.2:2007?

SIST EN 301 178-2 V1.2.2:2007 is built around a set of transmitter and receiver performance limits, plus the test methods used to demonstrate compliance. Most of the detailed definitions and limit values are taken from ETSI EN 301 178-1, while this part identifies which tests must be used and how results are judged.

Environmental profile and test conditions

Clause 4.1 requires testing at representative points within the declared operational environmental profile, and that profile must at least match the test conditions in the document. In practice, this means the equipment has to be checked under the environmental range it is claimed to support, not only in ideal laboratory conditions.

Clause 5.1 points to EN 301 178-1 for the detailed test conditions, power supply arrangements, and ambient temperature requirements. For users of the standard, this means the test plan must follow the companion part rather than inventing its own setup.

Transmitter requirements

Clauses 4.2.1 to 4.2.7 cover the transmitter. They address:

• frequency error
• carrier power
• frequency deviation
• adjacent channel power
• conducted spurious emissions conveyed to the antenna
• cabinet radiation and conducted spurious emissions other than those conveyed to the antenna
• transient frequency behaviour

Each requirement uses the definition and limit stated in EN 301 178-1, and each one has a corresponding test in clause 5.3. In practice, a supplier needs to measure not only the wanted signal, but also unwanted emissions and frequency stability, because those are the characteristics that affect interference to other maritime users.

Receiver requirements

Clauses 4.2.8 to 4.2.15 cover receiver performance. They include:

• maximum usable sensitivity
• co-channel rejection
• adjacent channel selectivity
• spurious response rejection
• intermodulation response
• blocking or desensitization
• conducted spurious emissions
• radiated spurious emissions

Clause 5.4 gives the corresponding test specifications. These checks matter because a receiver must still function when other signals are present nearby, and it must not create unwanted emissions of its own.

Measurement uncertainty and reporting

Clause 5.2 requires the measurement uncertainty for each parameter to be included in the test report, and the recorded uncertainty has to be within the values given in Table 1. The uncertainties are to be calculated using ETSI TR 100 028 with an expansion factor of k = 1,96 or k = 2.

In practice, this means a pass or fail decision is not based on the measured number alone. The uncertainty has to be known and reported, so laboratories can show that a result is reliable enough for compliance assessment.

Essential radio test suites and presumption of conformity

Clause 5.3 defines the Essential Radio Test Suite for transmitter requirements, and clause 5.4 defines the other receiver test specifications. Annex A, the HS-RTT table, ties each requirement to its clause reference, shows whether it is unconditional, and identifies whether the test is essential or other.

For buyers, engineers, and certification teams, Annex A is the practical map for compliance work. When the equipment schedule is completed with the test outcomes, it supports a presumption of conformity with Article 3.2.

What terms does SIST EN 301 178-2 V1.2.2:2007 define?

SIST EN 301 178-2 V1.2.2:2007 uses a small set of definitions and abbreviations that are important for reading the document correctly.

• Environmental profile - the range of environmental conditions under which the equipment is required to comply.
• Supplier - the entity responsible for placing the equipment on the market under the R&TTE Directive.
• Electro-Magnetic Compatibility (EMC) - the ability of equipment to operate without causing or suffering unacceptable interference.
• Global Maritime Distress and Safety System (GMDSS) - the maritime distress and safety system that this standard explicitly excludes from scope.
• Low Voltage (LV) - an abbreviation listed for use in the document.
• Radio and Telecommunications Terminal Equipment (R&TTE) - the directive framework named in the standard.
• Very High Frequency (VHF) - the frequency range used by the equipment in scope.
• electromotive force (emf) - an abbreviation listed in the document.

Who uses SIST EN 301 178-2 V1.2.2:2007?

SIST EN 301 178-2 V1.2.2:2007 is used by suppliers and manufacturers of portable maritime VHF radiotelephones when designing, verifying, and placing equipment on the market. It is also used by test laboratories that perform the transmitter and receiver measurements, record uncertainty, and compile the technical file.

Conformity assessment bodies and market surveillance authorities use it to check whether equipment claims for non-GMDSS maritime VHF use are supported by the required tests. Quality managers and buyers use it to confirm that a product has been assessed against the correct maritime radio standard, rather than a general-purpose radio standard.

What changed in SIST EN 301 178-2 V1.2.2:2007 from the previous edition?

The document history lists two published versions: V1.1.1 from August 2000 and V1.2.2 from February 2007. The present standard is the V1.2.2 publication.

Which standards are used with SIST EN 301 178-2 V1.2.2:2007?

• ETSI EN 301 178-1 (V1.3.1) - the companion part for this equipment family; it provides the technical definitions, limit values, and measurement procedures that Part 2 references for almost every requirement.
• ETSI TR 100 028 series (V1.4.1) - used to calculate measurement uncertainty for the test results.
• Directive 1999/5/EC (R&TTE Directive) - the legal framework for Article 3.2 that this harmonized EN is intended to support.
• Directive 98/34/EC - the directive mentioned in the foreword as the basis for the mandate under which ETSI produced the standard.

What does the SIST EN 301 178-2 V1.2.2:2007 document contain?

The document contains clause-by-clause technical requirements for transmitter and receiver performance, with each requirement linked to a matching conformance test. It also contains the test conditions framework, the measurement-uncertainty rules, and the Essential Radio Test Suite / other test specification split.

Annex A gives the HS-RTT table, which is the key compliance mapping tool. Annex B lists the title in official languages, and Annex C lists bibliography items. Table 1 sets the maximum absolute measurement uncertainties used when judging compliance.
