标准范围

本文件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在表面上具有室内光活性光催化膜的片状材料的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，水接触角是反映半导体光催化材料自清洁性能的指标之一。本文件不适用于水滴无法容纳的可渗透材料和遮挡水滴的粗糙材料。该文献不适用于由于附着的有机物的分解而导致的水接触角的变化无法评估的材料，因为即使表面是干净的，水接触角也非常大，或者有机物附着到表面不能充分增加水接触角。

This document 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.

This document 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.
