WORKING OF PLASTICS; WORKING OF SUBSTANCES IN A PLASTIC STATE IN GENERAL (processing doughs A21C; working chocolate A23G; casting of metals B22; working cement, clay B28; chemical aspects, see section C, particularly C08; working glass C03B; candle making C11C 5/02; making soap C11D 13/00; manufacture of artificial filaments, threads, fibres, bristles or ribbons D01D, D01F; manufacture of articles from cellulosic fibrous suspensions or from papier-mâche D21J)
 B29

Note(s)

  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:
    1. The working of plastics is, as far as possible, classified primarily according to the particular shaping technique used, e.g. in subclass B29C. [4]
    2. A product is not classified in this class unless it results from a technique which is covered by this class.
    3. Classification according to production of particular articles in subclass B29D is restricted to:
      1. aspects which are characteristic for the production of a particular article, and not classifiable in subclass B29B or B29C;
      2. 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]

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]
 B29B

Note(s)

In this subclass, it is desirable to add the indexing codes of subclass B29K. The indexing codes should be unlinked. [4]

 B29C

Note(s)

  1. Attention is drawn to Note (3) following the title of class B29. [4]
  2. When classifying in this subclass, classification is also made in subclass B32B insofar as any layered product is concerned. [4]
  3. In this subclass:
    (See paragraph 69 of the Guide.) [4,5]
  4. In this subclass, it is desirable to add the indexing codes of subclasses B29K and B29L. The indexing codes should be unlinked. [4]

Note(s)

Note(s)

  1. This subclass constitutes an indexing scheme associated with subclasses B29B, B29C or B29D. The indexing codes should be unlinked. [4]
