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.

  1. In this sub-section, the separation of different materials, e.g. of different matter, size, or state, is predominantly found in the following subclasses:

    B01D
    B03B, B03C, B03D
    B04B, B04C,
    B07B, B07C.

  2. The classifying characteristics of these subclasses are:
    1. the physical state of the matter to be separated;
    2. the principle of the process used;
    3. particular kinds of apparatus.

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

      1. liquid/liquid or liquid/gas and gas/gas;
      2. solid/liquid or solid/gas;
      3. solid/solid.

  3. These subclasses are to be used according to the following general rules:
    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.
  4. The following scheme illustrates the classification according to these rules.
