Zahteve za dostopnost izdelkov in storitev IKT
Ta dokument določa zahteve za funkcijsko dostopnost proizvodov in storitev IKT, vključno z opisom preskusnih postopkov in metodologijo ocenjevanja, za vsako zahtevo za dostopnost v obliki, ki bi se lahko uporabila pri javnem naročanju znotraj Evrope. Ta dokument je predviden za uporabo s spletnimi in nespletnimi tehnologijami ter hibridi, ki uporabljajo obe vrsti tehnologije. Zajema programsko in strojno opremo ter storitve. Namenjen je ponudnikom in naročnikom, vendar se pričakuje, da bo uporaben tudi za mnoge druge posameznike. Razmerje med tem dokumentom in bistvenimi zahtevami Direktive 2016/2102 o dostopnosti spletnih mest in mobilnih aplikacij organov javnega sektorja [i.28] je podano v dodatku A. Ta dokument vsebuje potrebne funkcijske zahteve in predstavlja referenčni dokument, tako da so rezultati preskušanja podobni in je razlaga teh rezultatov jasna, tudi če postopke spremljajo različni akterji. Opisi testov in metodologija ocenjevanja, ki so vključeni v tem dokumentu, so opredeljeni na ravni podrobne skladnosti s standardom ISO/IEC 17007:2009 [i.14], zato da je mogoče s preskušanjem skladnosti zagotoviti prepričljive rezultate.
