| Notes |
|
| (1) | In groups C03C 25/24 to C03C 25/54, in the absence of an indication to the contrary, classification is made in the last appropriate place. [7] |
|
| (2) | In groups C03C 25/24 to C03C 25/44, it is desirable to add the indexing codes relating to the individual constituents of the composition. The indexing codes, which are chosen from groups C03C 25/24 to C03C 25/44, have the same numbers as the classification symbols, but a colon is used instead of the oblique stroke and should be linked. [7] |
|
| (3) | 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. [7] |
