Annotation of standard text ČSN ISO 27447 (727405):

Tato mezinárodní norma specifikuje zkušební metodu pro stanovení antibakteriální účinnosti materiálů, které obsahují fotokatalyzátor nebo mají fotokatalytickou povrchovou úpravu, měřením počtu bakterií při ozařování ultrafialovým světlem. Tato mezinárodní norma je určena pro použití s různými druhy polovodičových fotokatalytických materiálů používaných ve stavebních materiálech, v plochých deskách, tabulích, tvarovaných deskách nebo textiliích, které jsou základními formami materiálů pro různé aplikace. Nezahrnuje práškové, granulované nebo porézní fotokatalytické materiály. Tato zkušební metoda je obvykle použitelná pro fotokatalytické materiály vyrobené pro antibakteriální účinek. Jiné typy vlastností fotokatalytických materiálů, tj. rozklad vodních kontaminantů, samočištění, zamlžování a čištění vzduchu, nejsou touto metodou stanoveny. Hodnoty vyjádřené v této mezinárodní normě jsou v souladu s mezinárodní soustavou jednotek (SI)
