DEFINITION

Classification: 422/1

PROCESS DISINFECTING, PRESERVING, DEODORIZING, OR STERILIZING:

(under the class definition) Process for maintaining a protective environment or counteracting destructive environment by disinfection, deodorizing, preserving, or sterilizing.

(1) Note. Manufacturing articles or stock material to be resistant to deterioration in use, as by adding a stabilizer or by processes of manufacture, are classifiable, per se, in; e.g., Classes 156, 264, 427, etc.

(2) Note. Manufacturing or processing steps classifiable, per se, in a class when combined with a step(s) proper for this class is classified in the, per se, class and crossed to this Class 422.
