Investigations showed differences between the two sets of yellow spot colour discs.

In October 2002 (10/02) the approved master set of EBC yellow spot discs was realigned to the reference CIE (Illuminant B) chromaticity co-ordinates published in 1997 in ANALYTICA-EBC. Changes to the discs were small and notifi cation to the brewing and malting industries was considered unnecessary.
