Accessibility requirements suitable for public procurement of ICT products and services in Europe

DEN/HF-00125

Zahteve za dostopnost pri javnem naročanju izdelkov in storitev IKT v Evropi

Ta dokument določa zahteve za funkcijsko dostopnost proizvodov in storitev IKT, vključno z opisom preskusnih postopkov in metodologije ocenjevanja, za vsako zahtevo za dostopnost v obliki, ki bi se lahko uporabila pri javnem naročanju znotraj Evrope. Ta dokument je morda uporaben tudi za druge namene, kot je naročanje v zasebnem sektorju. Ta dokument je predviden kot podlaga za orodje za dostopno naročanje IKT. Ta dokument bo zlasti uporaben za javne naročnike pri prepoznavanju zahtev svojih nakupov in tudi za proizvajalce za vključevanje v zasnovne postopke, proizvodne postopke in postopke kontrole kakovosti. Ta dokument vsebuje potrebne funkcijske zahteve in predstavlja referenčni dokument, tako da so rezultati testiranja podobni in je razlaga teh rezultatov jasna, tudi če postopke spremljajo različni akterji. Opisi testov in metodologija ocenjevanja, ki so vključeni v trenutnem dokumentu, so opredeljeni na nivoju podrobne skladnosti s standardom ISO/IEC 17007:2009 [i.14], zato da preizkušanje skladnosti zagotovi prepričljive rezultate. Zaradi značilnosti nekaterih situacij ni mogoče podati zanesljivih in dokončnih izjav, da so zahteve za dostopnost izpolnjene. Zato v takih situacijah zahteve v trenutnem dokumentu ne veljajo:
• če je izdelek okvarjen, v popravilu ali se na njem izvaja vzdrževanje, kar pomeni, da običajni nabor vhodnih ali izhodnih funkcij ni na voljo;
• med zagonom sistema, zaustavitvijo sistema in med drugimi prehodnimi stanji, ki se lahko izvedejo brez pomoči uporabnika.
OPOMBA 1: Tudi v že omenjenih primerih je najbolje, da zahteve v trenutnem dokumentu upoštevamo, kadar je to mogoče in varno.
OPOMBA 2: Skladnost je navedena v normativni točki C.1.
