ISO 13125:2013规定了一种试验方法，通过计算暴露于紫外线（UV-a）光下的预培养真菌孢子数量，测定含有光催化剂或表面有光催化膜的材料的抗真菌活性。 ISO 13125:2013规定了对各种应用中使用的材料的不同种类的评估，例如平涂层、薄板、板或平板形式的建筑材料等。不包括粉末、颗粒、纤维或多孔光催化材料。 ISO 13125:2013中表示的数值符合国际单位制（SI）。

ISO 13125:2013 specifies a test method covering the determination of the antifungal activity of materials that contain a photocatalyst or have photocatalytic films on their surface, by counting the number of pre-incubated fungal spores that survive exposure to ultraviolet (UV-A) light. ISO 13125:2013 provides for the assessment of different kinds on materials used in various applications, such as construction materials in flat coating, sheet, board or plate form, etc. Powder, granular, fibrous or porous photocatalytic materials are not included. Values expressed in ISO 13125:2013 are in accordance with the International System of Units (SI).
