Note(s)

  • The following notes are meant to assist in the use of this part of the classification scheme; they must not be read as modifying in any way the elaborations.
    • In this sub-section, the separation of different materials, e.g. of different matter, size, or state, is predominantly found in the following subclasses:
    • The classifying characteristics of these subclasses are:
      • the physical state of the matter to be separated;
      • the principle of the process used;
      • particular kinds of apparatus.

      The first of these characteristics involves six different aspects, assembled in three groups:

      • liquid/liquid or liquid/gas and gas/gas;
      • solid/liquid or solid/gas;
      • solid/solid.

    • These subclasses are to be used according to the following general rules:
      • B01D is the most general class as far as separation other than solids from solids is concerned.
      • Apparatus for separating solids from solids are covered by B03B when the process concerned is regarded as the equivalent of "washing" in the sense of the mining art, even if such apparatus is a pneumatic one, especially pneumatic tables or jigs. Screens per se are not covered by this subclass but are classified in B07B, even if they are being used in a wet process. All other apparatus for the separation of solids from solids according to dry methods are classified in B07B.
      • If the separation takes place as a result of the detection or measurement of some feature of the material or articles to be sorted it is classified in B07C.
      • It should also be noted that the separation of isotopes of the same chemical element is covered by B01D 59/00, whatever process or apparatus is employed.
