CONSTRUCTIONAL DETAILS OF INSTRUMENTS, OR COMPARABLE DETAILS OF OTHER APPARATUS, NOT OTHERWISE PROVIDED FOR
Definition statement
This subclass covers:

Only details which are restricted to mechanical measuring instrument.

Relationship between large subject matter areas

Details which already are covered by any other subclass in sections A, F, G or H are classified under those corresponding places and not under G12B.

References relevant to classification in this subclass/group
This subclass does not cover:

Details restricted to the measuring instruments covered by the relevant subclasses of class G01, e.g. G01D

Constructional details restricted to electric apparatus, e.g. casings, screenings

Constructional details restricted to electronic apparatus, e.g. casings, screenings

Informative references
Attention is drawn to the following places, which may be of interest for search:

Insulation or protection of buildings

Damping of shock or vibrations movement

Emergency protection of apparatus in general

Emergency protection of apparatus in general

Screening of lighting devices

Cooling by refrigeration

Heat-exchange or heat-transfer details

Special rules of classification within this subclass

Attention is drawn to the Notes following the IPC title of section G, especially as regards to the definition of the term "measuring" in Note (2) following the title of class G01.

Groups G12B 3/00, G12B 13/00, G12B 15/00, G12B 17/00 are not used anymore for classifying new documents.

Groups G12B 1/00, G12B 5/00, G12B 9/00 and G12B 11/00 are used only very rarely.

Glossary of terms
In this subclass, the following terms (or expressions) are used with the meaning indicated:

Apparatus:

a category of subject matter which is a machine or device, described in terms of its functional capabilities or structural features, that is used to make a product, or to carry out a non-manufacturing process or activity.

Sensitive elements capable of producing movement or displacement for purposes not limited to measurement; Associated transmission mechanicsms therefor
Definition statement
This group covers:

Actuating mechanisms of small size, e.g. Micromotion actuators for microdisplacement.

References relevant to classification in this group
This group does not cover:
