ISO 2810:2004规定了在选择天然风化类型时需要考虑的条件以及用于确定涂料或涂料体系（玻璃幕后直接耐候或耐候）的自然风化程序。 天然风化用于确定涂料或涂料体系（以下简称为涂料的文字）对太阳的辐射和气氛的抵抗力。 特殊的大气影响，例如工业污染没有被考虑

ISO 2810:2004 specifies the conditions which need to be taken into consideration in the selection of the type of natural weathering and the natural weathering procedure to be used to determine the resistance of coatings or coating systems (direct weathering or weathering behind window glass). Natural weathering is used to determine the resistance of coatings or coating systems (denoted in the following text simply by coatings) to the sun's radiation and the atmosphere. Special atmospheric influences, e.g. industrial pollution, are not taken into account.
