G01D MEASURING NOT SPECIALLY ADAPTED FOR A SPECIFIC VARIABLE; ARRANGEMENTS FOR MEASURING TWO OR MORE VARIABLES NOT COVERED IN A SINGLE OTHER SUBCLASS; TARIFF METERING APPARATUS; MEASURING OR TESTING NOT OTHERWISE PROVIDED FOR
Introduced: September 1968
Description
G01D provides a residual classification for measurement and testing technologies that are either generic in nature or do not fit within specialized subclasses dedicated to specific variables (such as length, temperature, or pressure). It covers multi-variable measurement systems where the combination of measured parameters cannot be classified under a single dedicated subclass, as well as tariff metering apparatus and generic transducing/transferring arrangements applicable across multiple measurement domains. This subclass also serves as a catch-all for measurement and testing methods or apparatus that lack adequate coverage in more specific G01 subclasses, making it essential for inventions with broad or cross-disciplinary measurement applications.

5 codes are CPC-only extensions.
Note: 5 CPC extensions are marked as secondary classification only.
6 shared codes have differing titles between IPC and CPC.
