Fine ceramics (advanced ceramics, advanced technical ceramics). Determination of bacterial reduction rate by semiconducting photocatalytic materials under indoor lighting environment. Semi-dry method for estimating antibacterial activity on the…1 Scope This document establishes a test method for determining the antibacterial activity of materials containing an indoor light active photocatalytic material on the surface. The antibacterial reduction rate is determined by measuring the survival of bacteria after illumination with indoor light. This test assumes a surface with high potential of possible person contact with bacteria. This test is designed to evaluate the suppression of contact
