In group C 04 B 35/66, it is desirable to add the indexing codes relating to individual constituents of the monolithic refractories or refractory mortars. The indexing codes, which are chosen from groups
C 04 B 7/00 to C 04 B 28/00, 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. [6] |
