CIE 121-SP1:2009

This report provides information regarding the photometric measurements of emergency lighting luminaires. It is the intention of this document to provide measurement methods for testing the compliance of emergency luminaires with the photometric requirements of IEC safety standards IEC 60598-2-22 and IEC 61347-2-7 issued by IEC/TC34 "Lamps and related equipment". Photometric methods for the measurement of other photometric parameters currently in use are also provided, but the measurement of safety signs is not included. Measurement procedures relate to the editions in use at the date of publication of this report and may vary for future editions. It is the responsibility of the laboratory to check for current applicable procedures. The concept of emergency ballast lumen factor applies only to emergency luminaires equipped with classical discharge lamps and for which a reference ballast has been normalised. For LED luminaires mostly absolute values apply, not related to the luminous flux of the LEDs alone.
