Le pr\u00e9sent document d\u00e9crit une m\u00e9thode d\u2019essai pour la d\u00e9termination de la performance en mati\u00e8re de purification de l\u2019air de mat\u00e9riaux contenant un photocatalyseur ou dont la surface est pourvue de films photocatalytiques, g\u00e9n\u00e9ralement constitu\u00e9s d\u2019oxydes m\u00e9talliques semi-conducteurs tels que le dioxyde de titane ou d\u2019autres mat\u00e9riaux c\u00e9ramiques, par exposition continue d\u2019un \u00e9chantillon \u00e0 un polluant atmosph\u00e9rique mod\u00e8le sous rayonnement de proche ultraviolet (UV). Le pr\u00e9sent document est destin\u00e9 \u00e0 \u00eatre utilis\u00e9 avec diff\u00e9rents types de mat\u00e9riaux tels que les mat\u00e9riaux de construction sous forme de feuilles, de plaques et d\u2019agglom\u00e9rats plans, qui constituent les diff\u00e9rentes formes de base des mat\u00e9riaux utilis\u00e9s pour diverses applications.
