1) Lamps with chromaticity coordinates that do not lie in the vicinity of the reference radiators (Judd lines; see
CIE calculation method) cannot, by definition, be assigned a colour temperature and hence cannot be assigned
a colour rendering index.

2.3.3 Chromaticity coordinates tolerance fields

Chromaticity coordinates tolerance fields are ellipses in the chromaticity table which represent the
permissible range for the relevant light colour. The tolerances are five threshold units for all light
colours (LUMILUX

®

, LUMILUX

DE LUXE).

A threshold unit represents the minimum perceivable difference in colour between two lamps (see
also IEC 60901 and IEC 60081).
