本文件规定了一种评估水泥砂浆和/或石灰或陶瓷基基质、涂料或材料中所含光催化无机材料性能的方法，这些材料以薄膜或涂层的形式沉积在各种基质上，用于光催化消除气相中的一氧化氮。本方法不适用于评估垂直于表面的流动或作为聚合物和纸质过滤器、蜂窝结构等渗透表面的流动所应用的样品。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies a method for assessing the performance of photocatalytic inorganic materials contained in cement mortars and/or limes or ceramic-based matrices, paints or materials deposited as thin films or coatings on a variety of substrates for the photocatalytic abatement of nitric oxide in the gas phase. This method does not apply to the assessment of samples to be applied with flow perpendicular to the surface or flow permeating the surface itself as polymeric and paper filters, honeycomb structures and suchlike.All current amendments available at time of purchase are included with the purchase of this document.
