This document specifies light emitting diodes (LED) for light source and radiometers used in the performance evaluation of semiconducting photocatalytic materials under indoor LED lighting environments in a laboratory. Light sources for indoor lighting environments do not include sunlight passing through window glass. This document does not replace ISO 14605.[1] Either document can apply depending on the lighting environment in which the photocatalytic material is used.
Abstract
Overview
ISO 24448:2023 defines laboratory light-source and radiometer requirements for evaluating semiconducting photocatalytic materials under indoor LED lighting. Developed by ISO/TC 206 (Fine ceramics), the standard ensures reproducible, comparable photocatalytic performance tests when white LED lamps are used in place of older fluorescent lamps. It explicitly covers LED characteristics, illuminance meter specifications, measurement conditions and required test-report information. Note: indoor lighting excludes sunlight passing through window glass.
Key topics and technical requirements
- LED light source
- Phosphor-type white LEDs with a peak emission at 450 nm ± 10 nm.
- CIE 1974 general colour rendering index (Ra): **80 ≤ Ra
