Tento dokument je určen pro použití různých typů materiálů, jako jsou stavební materiály ve tvaru plochého plechu, desky nebo desky, které jsou základními formami materiálů pro různé aplikace. Tento dokument se vztahuje také na materiály ve voštinové formě a na plastové nebo papírové materiály, pokud obsahují keramické mikrokrystaly a kompozity. Tento dokument se nevztahuje na práškové nebo granulované fotokatalytické materiály. Tato zkušební metoda je obvykle použitelná pro fotokatalytické materiály vyrobené pro čištění vzduchu. Tato metoda není vhodná pro stanovení jiných funkčních vlastností fotokatalytických materiálů, tj. rozkladu vodních kontaminantů, samočištění, protizamlžovačích a antibakteriálních účinků.
