Notes |
|
(1) | In groups B 03 D 1/001 to B 03 D 1/018, in the absence of an indication to the contrary, classification is made in the last appropriate place. [5] |
|
(2) | In groups B 03 D 1/001 to B 03 D 1/018, it is desirable to add the appropriate indexing code(s) from each of groups B 03 D 101:00 and B 03 D 103:00. The indexing codes should be unlinked. [5] |
