Division 3.3.5 Identification of units
United Kingdom
Each unit shall be clearly and unambiguously identifiable (e.g. by marking for hardware and marking or software output for software content) to provide corresponding hardware and documentation association.
Where functions are combined within a single unit or within a single computer, but shown in multiple blocks in the block diagram for clarity and ease of explanation, only a single hardware identification marking shall be used.
The manufacturer shall, by the use of this identification, affirm that the equipment supplied conforms to the corresponding document.
