Fine ceramics (advanced ceramics, advanced technical ceramics) -- Test method for air-purification performance of semiconducting photocatalytic materials by test chamber method under indoor lighting environment -- Part 1: Removal of formaldehyde
This test method is usually applicable to indoor-light-active photocatalytic materials produced for air purification. This method is not suitable for the determination of other performance attribute of photocatalytic materials, i.e. decomposition of water contaminants, self-cleaning, antifogging and antibacterial actions. This test method is based on ISO 16000‑23 and is adjusted for the measurement of indoor-light-active photocatalytic materials.
NOTE Another test method for the determination of air-purification performance of photocatalytic materials by using formaldehyde is described in ISO 22197‑4. The test methods comprising of ISO 22197 are prepared for evaluation of material-based air-purification performance under irradiation of ultraviolet light, while this part of ISO 18560 is intended for providing a direct index to the improvement of indoor air quality by the indoor-light-active photocatalytic materials under the simulated conditions. Approximate correlation between the results by ISO 22197‑4 and this part of ISO 18560 has been confirmed.
