Photometric methods for the measurement of other photometric parameterscurrently 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 reportand may vary for future editions. It is the responsibility of the laboratory to check for currentapplicable procedures. The concept of emergency ballast lumen factor applies only toemergency luminaires equipped with classical discharge lamps and for which a referenceballast has been normalised. For LED luminaires mostly absolute values apply, not related tothe luminous flux of the LEDs alone.
