IEC 81346

International Standard IEC/ISO 81346 series "Industrial systems, installations and equipment and industrial products – structuring principles and reference designations" [1] defines the rules for reference designation systems (RDS). It is published as a double logo standard prepared by IEC technical committee 3: Information structures and elements, identification and marking principles, documentation and graphical symbols, in cooperation with ISO technical committee 10: Technical product documentation. The 81346 series replaces the deprecated IEC 61346:1996.

gollark: Makes sense, then.
gollark: If you're paying for it with an egg, you'd have that slot taken anyway.
gollark: Would the egg they're offering not end up going to 6D0H anyway if you took it?
gollark: Assuming my maths is right, only about 30000 5-long `bug` codes can exist.
gollark: I would say "a destiny of being traded on to code collectors for some other dragon" but apparently not.
