ISO/CIE TS 22012 discusses maintenance factor determination of light and lighting. A lighting maintenance policy is a set of written procedures designed to serve as a guideline, not only for everyday maintenance practices but for optimizing lighting systems on a year-round basis.
ISO/CIE TS 22012 specifies a standardized way of working for determining the maintenance factor for both outdoor and indoor lighting installations using the methodology as described in CIE 154:2003 and CIE 097:2005.
ISO/CIE TS 22012 on light and lighting is useful for:
ISO/CIE TS 22012 provides background information with respect to the principles of the maintenance factor and the relevant parameters for indoor and outdoor applications.
ISO/CIE TS 22012 provides you with a detailed way of working on how to apply the maintenance factor determination method (as described in CIE 154:2003 and CIE 097:2005) for outdoor and indoor lighting designs using the technologies available in the market.
ISO/CIE TS 22012 gives you explanations and examples on how to apply the maintenance factor and how to ensure proper operation over time corresponding to the determined values.
