Standards Development
This International Standard specifies the LED light source and radiometers used in the performance evaluation of semiconducting photocatalytic materials used under an indoor LED lighting environment. A light source of an indoor lighting environment does not include the sunlight passing through the window glass. The ISO 14605 is not replaced by this ISO standard. An ISO standard to apply must be selected according to the lighting environment in which the photocatalytic material is used.
The ISO/AWI 24448 "Fine ceramics – LED light source for testing semiconducting photocatalytic materials used under indoor lighting environment" is currently being developed by ISO/TC 206. In the meantime, CEN/TC 386 has decided to convert the CEN/TS 16599 "Photocatalysis - Irradiation conditions for testing photocatalytic properties of semiconducting materials and the measurement of these conditions" into an EN standard.
The Project Leader Pr Georges ZISSIS has deemed necessary to gather these two parallel works into a same draft, and to work on an EN/ISO draft.
