| 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 B31. [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 B29C. [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 B29D is restricted to: |
|
| (i) | aspects which are characteristic for the production of a particular article, and not classifiable in subclass B29B or B29C; |
|
| (ii) | combined operations for making the particular article which are not fully classifiable in subclass B29C. [4] |
|
| (4) | The codes of subclass B29K are only for use as indexing codes associated with subclasses B29B, B29C, or B29D 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 B29L are only for use as indexing codes associated with subclass B29C, so as to provide information concerning the articles produced by the techniques classified in subclass B29C. [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 B23; grinding, polishing B24; cutting B26D, B26F; making preforms B29B 11/00) [4] |
|
| B 29 D | PRODUCING PARTICULAR ARTICLES FROM PLASTICS OR FROM SUBSTANCES IN A PLASTIC STATE (making granules B29B 9/00; making preforms B29B 11/00) [4] |
|
| B 29 K | INDEXING SCHEME ASSOCIATED WITH SUBCLASSES B29B, B29C OR B29D, 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 B29C, RELATING TO PARTICULAR ARTICLES [4] |
