Notes |
|
(1) | In this subclass, the following terms or expressions are used with the meanings indicated: [6] |
|
– | "fillers" includes pigments, aggregates and fibrous reinforcing materials; [6] |
|
– | "active ingredients" includes processing aids or property improvers, e.g. grinding aids used after the burning process or used in the absence of a burning process; [6] |
|
– | "mortars", "concrete" and "artificial stone" are to be considered as a single group of materials, and therefore, in the absence of an indication to be contrary, they include mortar, concrete and other cementitious compositions. [6] |
|
(2) | In groups C 04 B 7/00 to C 04 B 32/00, in the absence of an indication to the contrary, classification is made in the last appropriate place. [4] |
|
(3) | A composition classified in groups C 04 B 26/00 or C 04 B 28/00 is also classified in groups C 04 B 14/00 to C 04 B 24/00, if a filler or active ingredient is of interest. [4] |
|
(4) | In groups C 04 B 26/00 to C 04 B 30/00, it is desirable to add the indexing codes relating to individual constituents. The indexing codes, which are chosen from groups C 04 B 7/00 to C 04 B 24/00, with the exception of groups C 04 B 7/13, C 04 B 7/36 to C 04 B 7/60, C 04 B 9/11 to C 04 B 9/20, C 04 B 11/02 to C 04 B 11/036, C 04 B 11/28 and C 04 B 11/30, have the same numbers as the classification symbols, but a colon is used instead of the oblique stroke, and should be linked. [4] |
|
(5) | 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. [6] |
