G12B CONSTRUCTIONAL DETAILS OF INSTRUMENTS, OR COMPARABLE DETAILS OF OTHER APPARATUS, NOT OTHERWISE PROVIDED FOR
Introduced: September 1968
Description
G12B covers structural and mechanical components of measuring instruments and apparatus that are not classified in more specific instrument classes. This subclass addresses constructional elements such as housings, supports, protective casings, mechanical linkages, and mounting systems that are shared across multiple instrument types. It serves as a residual classification for instrument details that lack dedicated coverage elsewhere in the G12 group or other technical fields. Examples include instrument frames, protective enclosures, and mechanical assembly details of general applicability to various measurement and control devices.
IPC and CPC are identically structured here. All 9 subcodes exist in both systems.
6 shared codes have differing titles between IPC and CPC.
