SIST EN 301 843-2 V2.3.1:2026 is the SIST adoption of ETSI EN 301 843-2 V2.3.1, a harmonised European EMC standard for marine VHF radiotelephone transmitters and receivers. It specifies how to test and assess VHF radiotelephone equipment for the maritime mobile service, together with associated ancillary equipment, for use in a marine environment.

What does SIST EN 301 843-2 V2.3.1:2026 specify?

SIST EN 301 843-2 V2.3.1:2026 covers EMC assessment for VHF radiotelephone transmitters and receivers operating in the frequency range 156 MHz to 174 MHz, plus associated ancillary equipment. It gives the test conditions, performance assessment, and performance criteria needed to judge the equipment’s EMC behavior in marine use.

The scope excludes technical specifications for the antenna port and for emissions from the enclosure port of marine radiotelephone transmitters and receivers. Those items are handled in related product standards aimed at effective use of the radio spectrum, so this part is mainly the EMC test and evaluation standard.

The document is organized into these main clauses and annexes:

• Clause 1 - Scope
• Clause 2 - References
• Clause 3 - Terms, symbols and abbreviations
• Clause 4 - General and operational requirements
• Clause 5 - Performance assessment
• Clause 6 - Performance criteria
• Clause 7 - Applicability overview
• Annex A - Relationship with Directive 2014/53/EU
• Annex B - Bibliography
• Annex C - Change history

Annex A links the standard to the essential requirements of Directive 2014/53/EU, which matters for compliance work and conformity assessment.

What are the key requirements of SIST EN 301 843-2 V2.3.1:2026?

SIST EN 301 843-2 V2.3.1:2026 builds on ETSI EN 301 843-1 and then adds product-specific conditions for marine VHF radiotelephone equipment. The most important points are the test signal arrangements, the exclusion bands, the performance checks, and the way emission and immunity tests are applied by equipment class.

Test setup and signal arrangements

Clause 4 uses the general arrangements from ETSI EN 301 843-1, but adds conditions specific to transmitter, receiver, and combined system tests. For transmitter input testing, the signal is applied at the microphone input directly or through an acoustic coupler if needed, which matters when the product has no direct microphone connection.

For receivers with an integral GNSS receiver, clause 4.2.3.1 requires a GNSS source outside the test area and re-radiated into the test environment. In practice, this means the GNSS signal has to be controlled during immunity testing so the receiver can be checked under a known wanted signal condition.

For marine communication receiver tests, clause 4.2.3.2 requires normal test modulation on the wanted RF input signal. Clause 4.2.5 also states that combined transmitter and receiver testing uses two EUT samples when the equipment operates at the same frequency, which matters for system-level verification.

Exclusion bands and test modulation

Clause 4.3 defines exclusion bands for receiver and transmitter tests. These are frequency ranges where emission measurements or immunity testing are not carried out, so test labs do not judge the equipment in areas where the wanted signal or receiver behavior would distort the result.

Clause 4.3.1 covers receiver-side exclusion bands, including GNSS-related bands and the marine communication receiver switching range. Clause 4.3.2 fixes the transmitter exclusion band around CH16, which is the distress, urgency and safety channel used for the testing conditions in this document.

Clause 4.4 says narrowband intermediate-frequency responses on receivers are disregarded from immunity tests. That keeps the test focused on normal operating behavior rather than narrow responses that are not relevant to the intended service.

Clause 4.5 fixes the test modulation for both transmitter and receiver testing. For users, that means the same defined modulation is used throughout the assessment, so results stay comparable across laboratories.

Performance assessment and criteria

Clause 5 says equipment that can provide a continuous communication link and equipment that cannot are assessed using the corresponding rules from part 1. It also says ancillary equipment supplied with the EUT is connected according to the operating instructions and tested as a system, which matters when the product is sold with accessories that affect EMC performance.

Clause 5.5 states that radiotelephone transmitters and receivers may be classed as mobile or portable marine radio equipment. That classification controls which emission and immunity tables apply in clause 7.

Clause 6 uses performance criteria A, B, and C from part 1. During radiated and conducted immunity testing, the speech output SINAD has to remain at least 20 dB, so the receiver must stay intelligible enough for practical marine communication.

For transmitter performance checks, clause 6.4.1 looks at RF output power, frequency error, and demodulated SINAD. For receiver performance checks, clause 6.4.2 requires GNSS receiver position fix checks or VHF marine receiver SINAD checks on CH16 with a fixed RF input level.

Emission and immunity applicability

Clause 7 sets out which EMC tests apply to mobile and portable equipment. Emission requirements cover radiated emission from the enclosure port and conducted emission on DC and AC power ports, while immunity requirements cover RF field, ESD, fast transients, RF common mode, supply variations, power failure, and surges as applicable.

The special conditions in clause 7 tie the emission and immunity tests back to the exclusion bands in clause 4.3. For test teams, that means the actual pass/fail evaluation depends not only on the generic EMC setup from part 1, but also on the product-specific marine radio conditions in this part.

What terms does SIST EN 301 843-2 V2.3.1:2026 define?

SIST EN 301 843-2 V2.3.1:2026 uses the terms from ETSI EN 301 843-1 and adds a few abbreviations that are important for testing.

• GNSS - Global Navigation Satellite System. In this document, GNSS is the navigation signal source used when the equipment has an integral GNSS receiver.
• SINAD - signal + noise + distortion / (noise + distortion). This is the audio quality measure used to judge receiver performance and immunity.
• EUT - equipment under test. This is the radio equipment being assessed in the EMC test.
• Exclusion band. This is the frequency range excluded from certain EMC measurements or immunity tests.
• Switching range. This is the maximum receiver tuning range available without reprogramming or realignment.
• Performance check. This is the post-test measurement used to confirm transmitter output, receiver reception, or GNSS position fix behavior.
• Ancillary equipment. This is extra equipment supplied with the EUT and tested together with it as a system.

Who uses SIST EN 301 843-2 V2.3.1:2026?

SIST EN 301 843-2 V2.3.1:2026 is used by manufacturers of marine VHF radiotelephone transmitters and receivers, EMC and radio test laboratories, and conformity assessment teams. It is also relevant to quality managers and buyers who need to verify that marine radio equipment is being assessed against the right EMC standard.

In practice, users apply it when designing products, planning EMC tests, checking receiver and transmitter performance, preparing technical documentation, and supporting regulatory conformity work for marine radio equipment and its ancillary equipment.

What changed in SIST EN 301 843-2 V2.3.1:2026 from the previous edition?

SIST EN 301 843-2 V2.3.1:2026 adds a new clause for GNSS exclusion bands, defines the test frequency as Distress/Urgency/Safety CH16 throughout the document, and adds a clearer categorization of ancillary equipment in clause 5.4. It also tightens the definition of RF power levels in clause 6.4.1 and replaces narrative text in clause 7 with definitive tables.

Which standards are used with SIST EN 301 843-2 V2.3.1:2026?

SIST EN 301 843-2 V2.3.1:2026 depends on ETSI EN 301 843-1 (V2.3.1), which provides the common technical requirements for the series. Part 1 supplies the shared terms, symbols, abbreviations, environmental profile, baseline test arrangements, and general EMC test framework that part 2 applies and modifies for marine VHF radiotelephone equipment.

What does the SIST EN 301 843-2 V2.3.1:2026 document contain?

SIST EN 301 843-2 V2.3.1:2026 contains the test arrangements for transmitter, receiver, GNSS, and combined system testing, including the step-by-step setup for establishing the wanted GNSS signal level. It also includes the exclusion-band rules, the receiver narrowband-response handling, and the fixed test modulation used for both transmitter and receiver checks.

The document’s tables are important for lab work because they map emission and immunity phenomena to mobile and portable equipment, and then add special conditions for marine radio use. Annex A provides the regulatory mapping to Directive 2014/53/EU, Annex B lists a bibliography item, and Annex C records the change history for this edition.
