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:
Fulltext... Hierarchy... Expanded...B01D Fulltext... Hierarchy... Expanded...B03B, Fulltext... Hierarchy... Expanded...B03C, Fulltext... Hierarchy... Expanded...B03D Fulltext... Hierarchy... Expanded...B04B, Fulltext... Hierarchy... Expanded...B04C Fulltext... Hierarchy... Expanded...B07B, Fulltext... Hierarchy... Expanded...B07C. - 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:
- The following scheme illustrates the classification according to these rules.
