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:
