| Notes |
|
| (1) | This class does not cover the working of plastics sheet material in a manner analogous to the working of paper, which is covered by class B 31. [4] |
|
| (2) | In this class, the following term is used with the meaning indicated: |
|
| – | "plastics" means macromolecular compounds or compositions based on such compounds. |
|
| (3) | In this class, the following rules apply: |
|
| (a) | The working of plastics is, as far as possible, classified primarily according to the particular shaping technique used, e.g. in subclass B 29 C. [4] |
|
| (b) | A product is not classified in this class unless it results from a technique which is covered by this class. |
|
| (c) | Classification according to production of particular articles in subclass B 29 D is restricted to: |
|
| (i) | aspects which are characteristic for the production of a particular article, and not classifiable in subclass B 29 B or B 29 C; |
|
| (ii) | combined operations for making the particular article which are not fully classifiable in subclass B 29 C. [4] |
|
| (4) | The codes of subclass B 29 K are only for use as indexing codes associated with subclasses B 29 B, B 29 C, or B 29 D so as to provide information concerning moulding materials or materials for reinforcements, fillers or preformed parts, e.g. inserts. [4] |
|
| (5) | The codes of subclass B 29 L are only for use as indexing codes associated with subclass B 29 C, so as to provide information concerning the articles produced by the techniques classified in subclass B 29 C. [4] |
|
| B 29 B | PREPARATION OR PRETREATMENT OF THE MATERIAL TO BE SHAPED; MAKING GRANULES OR PREFORMS; RECOVERY OF PLASTICS OR OTHER CONSTITUENTS OF WASTE MATERIAL CONTAINING PLASTICS [4] |
|
| B 29 C | SHAPING OR JOINING OF PLASTICS; SHAPING OF SUBSTANCES IN A PLASTIC STATE, IN GENERAL; AFTER- TREATMENT OF THE SHAPED PRODUCTS, e.g. REPAIRING (working in the manner of metal B 23; grinding, polishing B 24; cutting B 26 D, B 26 F; making preforms B 29 B 11/00) |
|
| B 29 D | PRODUCING PARTICULAR ARTICLES FROM PLASTICS OR FROM SUBSTANCES IN A PLASTIC STATE (making granules B 29 B 9/00; making preforms B 29 B 11/00) |
|
| B 29 K | INDEXING SCHEME ASSOCIATED WITH SUBCLASSES B 29 B, B 29 C OR B 29 D, RELATING TO MOULDING MATERIALS OR TO MATERIALS FOR REINFORCEMENTS, FILLERS OR PREFORMED PARTS, e.g. INSERTS [4] |
|
| B 29 L | INDEXING SCHEME ASSOCIATED WITH SUBCLASS B 29 C, RELATING TO PARTICULAR ARTICLES [4] |
