INDEXING SCHEME ASSOCIATED WITH SUBCLASS C10M  [4]
 C10N

Note(s)

  1. This subclass constitutes an indexing scheme for non-obligatory use only. The indexing scheme may be used to identify "additional information", which constitutes further information about subject matter already classified in subclass C10M. The indexing codes of this subclass, of which only the pertinent ones should be selected, are added in conformity with paragraph 76 of the Guide so as to provide information concerning: [4]
    These indexing codes should be presented as unlinked to the classification symbols with which they are associated, in conformity with paragraph 85 (b) of the Guide. [4]
  2. In this subclass, the following terms or expressions are used with the meanings indicated: [4]
    • "lubricant" or "lubricating composition" includes cutting oils, hydraulic fluids, metal drawing compositions, flushing oils, slushing oils, or the like; [4]
    • "aliphatic" includes "cycloaliphatic". [4]
