21/30403033 DC

This standard 21/30403033 DC BS EN ISO 24448. Fine ceramics (advanced ceramics, advanced technical ceramics). LED light source for testing semiconducting photocatalytic materials used under indoor lighting environment is classified in these ICS categories:

• 81.060.30 Advanced ceramics

This International Standard specifies the light emitting diode (LED) for light source and radiometers used in the performance evaluation of semiconducting photocatalytic materials used under indoor LED lighting environments in a laboratory. 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 shall be selected according to the lighting environment in which the photocatalytic material is used.
