This is really a European question but all are free to chip in.
It has come to my attention that the item designations used for many years in electrical drawings have been superseded. I'm talking about -105K1 as an example being the 1st relay on page 105 of a set of drawings.
The designation "K" comes from the standard AS3702-1989 where "K" is designated: "Relays, contactors"
AS3702 has been replaced by IEC 81346 and table 1 of part 2 now describes "K" as "object for treating input signals and providing an
appropriate output"
My question is: Does anyone actually use IEC 81346 for item designations or is everyone still using AS3702?
