标准范围

ISO 19810:2017规定了在室内照明环境下，测定含有室内光活性光催化剂或表面有室内光活性光催化薄膜的片状材料自清洁性能的试验方法。该方法用于测量室内光照环境下水接触角的变化，这是反映半导体光催化材料自清洁性能的指标之一。ISO 19810:2017不适用于水滴无法附着的渗透材料和遮挡水滴的粗糙材料。本文件不适用于因附着的有机物分解而导致的水接触角变化无法评估的材料，因为即使表面清洁，水接触角也非常大，或者通过将有机物附着到表面无法充分增加水接触角。

ISO 19810:2017 specifies a test method for the determination of the self-cleaning performance of sheet-form materials that contain an indoor-light-active photocatalyst or have indoor-light-active photocatalytic films on the surface, under indoor lighting environment.This method is used to measure the change of water contact angle under indoor lighting environment, which is one of the indices reflecting the self-cleaning performance of semiconducting photocatalytic materials.ISO 19810:2017 is not applicable to permeable materials on which water droplets cannot hold and rough materials which obscure water droplets. This document is not applicable to materials of which the changes in the water contact angle due to decomposition of adhered organic matter cannot be evaluated because even if the surface is clean the water contact angle is remarkably large or the water contact angle cannot be sufficiently increased by attaching organic matter to the surface.
