RE: Part names

Thanks for the responses, I think I have managed to piece it together. In the document above there was a link to the cpic website (the link didn't actually work) but searching around on there website I have found:

In general, the following mappings hold between Uniclass2 and the previous Uniclass:
Ac – Activities is new to both ISO 12006-2 and to Uniclass
Co – Complexes will replace parts of table D (Facilities)
Ee – Elements will replace table G (Elements)
EF – Entities by Form will replace parts of table D (Facilities)
En – Entities will replace parts of table D (Facilities)
PP – Project Phases is new to both ISO 12006-2 and to Uniclass
Pr – Products will replace table L (Construction Products)
Sp – Spaces will replace parts of table D (Facilities)
Ss – Systems is new to both ISO 12006-2 and to Uniclass
WR – Work Results will replace table J (Work sections for buildings) and table K (Work sections for civil engineering works)
Zz – CAD is new to both ISO 12006-2 and to Uniclass

So, it looks like the reason I can't seem to find G2613, is because it has been superseded (in the Uniclass tables at least)
