3.6

registration number

unique number assigned each graphical symbol (3.1)

Note 1 to entry: In principle, this number is arbitrarily chosen. No information can be derived from it.

Note 2 to entry: The registration number remains unchanged throughout the lifetime of the corresponding graphical symbol, including in future revisions of this document. If a graphical symbol is slightly changed in the future, the registration number shall be supplemented with one or more characters. If the graphical symbol is substantially changed, it shall instead be given a new registration number.

Note 4 to entry: Annex C specifies common registration number rules for ISO 14617-2 and derived collective application standards.

Note 5 to entry: ”GSD” was added in front of registration numbers defined in the previous edition of the ISO 14617 series. The reason is to distinguish the graphical symbols in the ISO 14617 series from those defined by other standards on the ISO Online browsing platform. “GSD” stands for graphical symbols for diagrams.
