JTC 11 (CIE-ISO): Light and Lighting – Maintenance factor – Way of working
This deliverable will provide a standardized way of working for determining the maintenance factor for both indoor and outdoor installations using the methodology as described in CIE 154:2003 & CIE 97:2005.
The deliverable will combine insights from IEC standards w.r.t. product performance of luminaires and light sources currently in the market with the existing determination methodology from CIE technical reports. Furthermore, it will reference to the data in the CIE technical reports w.r.t. the impact of the environment on luminaires (accumulation of dirt on surfaces and luminaires).
