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 should, as far as possible, be 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;
aspects which are characteristic for the production of a particular article, and not classifiable in subclass Fulltext... Hierarchy... Expanded...B29B or C; [4]
This subclass constitutes an indexing scheme for non-obligatory use only. The indexing scheme may be used to identify additional information, which constitutes further information about subject matter already classified in subclasses Fulltext... Hierarchy... Expanded...B29B, Fulltext... Hierarchy... Expanded...B29C or Fulltext... Hierarchy... Expanded...B29D. The indexing codes of this subclass, of which only the pertinent ones should be selected, are added in conformity with paragraph 76 of the Guide so as to provide information concerning the materials used. These indexing codes should be presented as unlinked to the classification symbols with which they are associated, in conformity with paragraph 85 (b) of the Guide. [4]
In this subclass, the following term is used with the meaningindicated: [4]
"rubber" covers: [4]
natural or conjugated diene rubbers; [4]
rubber in general (for a specific rubber, other than a natural rubber or a conjugated diene rubber, see the group provided for such macromolecular compounds). [4]

Cellulose, modified cellulose or cellulose derivatives, e.g. viscose [4]
