Application Summary AI generated

This standard specifies a semi-dry testing method for measuring the bacterial reduction rate of photocatalytic materials under indoor lighting conditions. It is applied in the glass and ceramics industry to evaluate the antibacterial activity of photocatalytic coatings on surfaces such as tiles, windows, or sanitary ware, simulating real-world contamination scenarios. The method is particularly relevant for quality control and product certification of self-cleaning or antimicrobial building materials used in indoor environments.
