ISO 10820:2025

Fine ceramics (advanced ceramics, advanced technical ceramics) — Ultraviolet irradiation equipment using UV-A LEDs and optical radiometry for performance test of semiconducting photocatalytic materials

Scope

This document specifies the irradiation equipment using ultraviolet light emitting diode (UV-LED) and optical radiometry for testing the performance of semiconducting photocatalytic materials. The UV-LED irradiation equipment specified in this document uses UV-LEDs having a peak wavelength of 365 nm in the UV-A range and applies for a semiconductor photocatalyst exhibiting a photocatalytic function at this wavelength.
This document applies only to irradiation equipment using UV-LED. ISO 10677[2] is applicable for equipment using conventional UV light sources such as fluorescent lamps.
