Anm.: -1 gesamter Farbbereich (siehe Seite 4)
Die Standardlieferform von Serientypen beinhaltet eine untere bzw. obere Familiengruppe. Diese
besteht aus
3 bzw. 4 Helligkeitshalbgruppen. Einzelne Helligkeitshalbgruppen sind nicht
bestellbar.
In einer Verpackungseinheit / Gurt ist immer nur eine Helligkeitshalbgruppe enthalten.
Note: -1 Total color tolerance range (see page 4)
The standard shipping format for serial types includes a lower or upper family group of
3 or 4 individual luminous intensity half groups. Individual luminous intensity half groups cannot be
ordered.
No packing unit / tape ever contains more than one luminous intensity half group.
