Use RAL 9005 As A Colour Reference
Record RAL 9005 explicitly in the interior brief, together with the fact that it concerns the base. This avoids extending the colour requirement to the seat or backrest without justification. Establish which surrounding elements need coordination and where a close visual relationship matters most within the proposed office room arrangement.
Compare jet-black base office chairs with unspecified standards using representative surfaces where possible. The colour reference does not settle questions of texture or gloss. Review those characteristics in context, and document acceptable variation so that colleagues assessing the seating understand exactly which aspects of the visual result matter to the brief.
Keep Colour Separate From Construction And Care
A jet-black base description does not identify the underlying material or explain how its surface was produced. Ask for the information needed to plan care. Do not infer a cleaning method, protective treatment or resistance characteristic from the colour reference, even where another black surface appears similar in the room.
Connect the relevant instructions with the office cleaning routine. Identify who needs the guidance and how any concerns about the base should be reported. Review accessible surfaces and floor contact points during inspection, keeping the practical care assessment tied to the actual chair rather than to assumptions about black finishes.
