DETAILS OF INSTRUMENTS, OR COMPARABLE DETAILS OF OTHER APPARATUS, NOT OTHERWISE PROVIDED FOR
G12B
Note(s)
This sub-class includes only details which are not restricted to measuring instruments or to any other apparatus covered by a single class. Details which are covered by any other sub-class in Section A, F, G, or H are classified in the relevant sub-class. In particular, details which are restricted to measuring instruments are covered by the relevant sub-class of class Fulltext... Hierarchy... Expanded...G01, e.g. Fulltext... Hierarchy... Expanded...G01D.
Constructional details restricted to electric apparatus, e.g. casings, screenings, are covered by sub-class Fulltext... Hierarchy... Expanded...H05K or the relevant sub-class in Section H.
Attention is drawn to the notes on scope on page [G 3] of this Section, in particular to the definition of "measuring" in Note (2).
