| | B21 | MECHANICAL METAL-WORKING WITHOUT ESSENTIALLY REMOVING MATERIAL; PUNCHING METAL |
| | | Note(s) - This class does not cover:
- combinations of operations covered by different subclasses of class B21, which are covered by subclass B23P;
- combinations of operations covered by any particular subclass of class B21 with operations covered by other classes, e.g. with operations involving removal of material, which are also covered by subclass B23P, except that if the operations covered by the other classes are subsidiary to the operations properly covered by a single subclass of B21 the combination is classified in that subclass.
- Processes of a kind covered by this class but applied to non-metallic materials are classified in this class if they are applicable to metal and cannot be classified fully in another class.
|
| | B22 | CASTING; POWDER METALLURGY |
| | B23 | MACHINE TOOLS; METAL-WORKING NOT OTHERWISE PROVIDED FOR |
| | | Note(s) - This class covers:
- operations not provided for in any other class;
- combinations of operations covered by different subclasses of classes B21-B24, which combinations are covered by subclass B23P, with the exception of subsidiary operations performed in conjunction with main operations covered by a single subclass;
- features, specific to machine tools, which relate to a requirement or problem of a nature which is not peculiar to a particular kind of machine tool, e.g. feeding work, which are covered by subclass B23Q, although the realisation of these features may differ according to the kind of machine tool concerned. The said subclass covers such features, in general, even if the feature or a specific function, in any particular case, is to some extent peculiar to, or is claimed only for, machine tools designed for one particular operation; only in exceptional cases are such features classified in the subclass for the machine tool concerned. Certain features of this general nature are, however, referred to subclasses relating to particular metal-working operations, especially B23B, in which case the subclasses in question are not restricted, in respect of those features, to the kind of machine tool with which they are primarily concerned.
- In this class, the following terms or expressions are used with the meanings indicated:
- "metal-working" covers the working of other materials unless the context requires otherwise;
- "kind of operations" and similar expressions relate to such metal-working operations as boring, drilling, milling and grinding;
- "kind of machine" means a machine designed for a particular kind of metal-working operation (e.g. a lathe);
- "form of machine" means a machine of a particular kind adapted or arranged for a particular way of working or for particular work, e.g. face-plate lathe, tailstock lathe, turret lathe;
- "different machines" covers different forms of machines for performing the same type of metal-working operation, e.g. vertical and horizontal boring machines.
- If details, components, or accessories have no essential feature specific to machine tools, the more general class, e.g. F16, takes precedence.
|

- 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 B29C.
- Classification according to production of particular articles in subclass B29D is restricted to:
- aspects which are characteristic for the production of a particular article, and not classifiable in subclass B29B or B29C;
- combined operations for making the particular article which are not fully classifiable in subclass B29C.
- Products per se are not classified in this class. However, if a product is characterised by the way it is produced and not by its structure or composition, the production method should be classified in this class.
- 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.
- 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.

| | B31 | MAKING PAPER ARTICLES; WORKING PAPER |
| | | Note(s) - This class covers subject matter restricted to adaptations or associations of handling sheets, webs, or blanks peculiar to paper-working, e.g. bag or box making, machinery.
- This class does not cover:
- making articles directly from paper pulp, which is covered by D21J;
- handling sheets, webs, or blanks of wider applicability, irrespective of whether described or claimed only for paper-working machinery, which is regarded as being of a more comprehensive nature and is covered by B65H.
