VHF radiotelephone equipment for general communications and associated equipment for Class D Digital Selective Calling (DSC) - Harmonised Standard covering the essential requirements of articles 3.2 and 3.3(g) of the Directive 2014/53/EU

The present document covers the minimum requirements for general communication for shipborne fixed installations using
a VHF radiotelephone operating in certain frequency bands allocated to the maritime mobile service using either 25 kHz
or 25 kHz and 12,5 kHz channels and associated equipment for DSC - class D.
These requirements include the relevant provisions of the ITU Radio Regulations, appendix 18 [1], Recommendations
ITU-R M.493-13 [3] (where class D is defined), M.825-3 [i.4] and incorporate the relevant guidelines of the IMO as detailed
in IMO Circular MSC/Circ-803 [i.1].
The present document also specifies technical characteristics, methods of measurement and required test results.
The present document contains requirements to demonstrate that "... Radio equipment shall be so constructed that it both
effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference" [i.3] and that
"....radio equipment supports certain features ensuring access to emergency services" [i.3].
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of article 3 of the Directive 2014/53/EU [i.3] may apply to equipment within the scope of the present
document.

Radiotelefonska oprema za območje VHF za splošne komunikacije in pripadajoča oprema za digitalni selektivni klic (DSC) razreda D - Harmonizirani standard, ki zajema bistvene zahteve členov 3.2 in 3.3(g) direktive 2014/53/EU

Ta dokument zajema minimalne zahteve za splošno komunikacijo z ladijskimi, stalno nameščenimi napravami z radiotelefonom VHF, ki deluje v določenih frekvenčnih pasovih, dodeljenih pomorskim mobilnim storitvam, ki uporabljajo kanale 25 kHz ali 25 kHz in 12,5 kHz in ustrezno opremo za digitalni selektivni klic (DSC) razreda D.
Te zahteve vsebujejo ustrezne določbe ITU pravilnika o radiokomunikacijah, dodatek 18 [1], priporočila ITU-R M.493-13 [3] (v katerih je določen razred D), M.825-3 [i.4] in vključujejo ustrezne smernice IMO, kot so opisane v okrožnici IMO MSC/Circ-803 [i.1].
Ta dokument določa tudi tehnične karakteristike, merilne metode in zahtevane rezultate preskusov. Ta dokument zajema zahteve za dokaz, da »... je radijska oprema sestavljena tako, da učinkovito uporablja in tudi podpira učinkovito uporabo radijskega spektra, tako da ne pride do škodljivega motenja« [i.3], ter da »... radijska oprema podpira določene funkcije, ki zagotavljajo dostop do storitev za nujne primere« [i.3].
Poleg tega dokumenta se lahko za opremo na področju uporabe tega dokumenta uporabljajo tudi drugi standardi EN, ki določajo tehnične zahteve v zvezi z bistvenimi zahtevami iz drugih delov člena 3 Direktive 2014/53/EU [i.3].
