Note(s) 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 Fulltext... Hierarchy... Expanded...B31. [4] In this class, the following term is used with the meaning indicated: "plastics" means macromolecular compounds or compositions based on such compounds. In this class, the following rules apply: The working of plastics is, as far as possible, classified primarily according to the particular shaping technique used, e.g. in subclass Fulltext... Hierarchy... Expanded...B29C. [4] A product is not classified in this class unless it results from a technique which is covered by this class. Classification according to production of particular articles in subclass Fulltext... Hierarchy... Expanded...B29D is restricted to: aspects which are characteristic for the production of a particular article, and not classifiable in subclass Fulltext... Hierarchy... Expanded...B29B or Fulltext... Hierarchy... Expanded...B29C; combined operations for making the particular article which are not fully classifiable in subclass Fulltext... Hierarchy... Expanded...B29C. [4]

|  | B29 - B29L |
Note(s) The codes of subclass Fulltext... Hierarchy... Expanded...B29K are only for use as indexing codes associated with subclasses Fulltext... Hierarchy... Expanded...B29B, Fulltext... Hierarchy... Expanded...B29C, or Fulltext... Hierarchy... Expanded...B29D so as to provide information concerning moulding materials or materials for reinforcements, fillers or preformed parts, e.g. inserts. [4] The codes of subclass Fulltext... Hierarchy... Expanded...B29L are only for use as indexing codes associated with subclass Fulltext... Hierarchy... Expanded...B29C, so as to provide information concerning the articles produced by the techniques classified in subclass Fulltext... Hierarchy... Expanded...B29C. [4]
