C 10 NINDEXING SCHEME ASSOCIATED WITH SUBCLASS C10M  [4]


Notes

(1)This subclass constitutes an indexing scheme associated with subclass C10M, relating to:

 metals and the metal of a compound (C10N 10:00);

 the properties of the lubricant composition or constituents thereof (C10N 20:00, C10N 30:00);

 the use or application of the lubricant composition (C10N 40:00);

 the form in which the lubricant composition is applied (C10N 50:00);

 chemical modification by after-treatment of lubricant constituents (C10N 60:00);

 special methods of preparation (C10N 70:00);

 special pretreatment of the material to be lubricated (C10N 80:00).

 The indexing codes should be unlinked.

 Attention is drawn to Chapter IV of the Guide which sets forth the rules concerning the application and presentation of the different types of indexing code.

(2)In this subclass, the following terms or expressions are used with the meanings indicated:

 "lubricant" or "lubricating composition" includes cutting oils, hydraulic fluids, metal drawing compositions, flushing oils, slushing oils, or the like;

 "aliphatic" includes "cycloaliphatic".  [4]
