(under the class definition) Processes in which (a) a process parameter in a qualitative or quantitative chemical analysis is determined and that or another process parameter of the analysis is changed in response to the analysis or (b) a process parameter in a chemical process is determined by a qualitative or quantitative chemical analysis and some parameter of the process is changed in response to the analysis and such condition responsive control is not other wise classifiable in the class providing for the chemical process.
(1) Note. In general each chemical class provides for control of its own processes even when such control is responsive to a qualitative or quantitative chemical analysis. To be properly classifiable in this class a condition responsive control of a process should be unclassifiable in the class providing for the chemical process in question.
