Subclasses list

Definition

(1) This is the generic class for processes and apparatus for making a measurement of any kind or for making a test of any kind, and takes all such subject matter not provided for in other classes.

(2) The term "test" includes inspection, processes and apparatus for determining qualities by inspection being included where not provided for in other classes.

(3) This class is the generic class for sampling and takes all sampling apparatus and processes not otherwise provided for; see subclasses 863+ and the notes thereto.

Notes

(1) Note. Processes and apparatus for its practice are classified together. (2) Note. Substantially all apparatus classes have means to automatically control the operation of the apparatus. Such automatic controls usually involve some means to measure or test a condition or change of condition, the measuring or testing means then operating to control or regulate the apparatus in accordance with the results of the measurement or test. For such subject matter, the class appropriate to the type of apparatus controlled should be investigated. No attempt has been made to search note automatic controls.
