Definition statement

This subclass covers:

Apparatus or methods for the separation of solids from solids that include:

Relationship between large subject matter areas

In Section B, the separation of different materials, e.g. of different matter, size, or state, is predominantly found in the following subclasses: B01DB03B, B03CB03D, B04BB04C, B07BB07C.

The classifying characteristics of these subclasses are:

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

These subclasses are to be used according to the following general rules:

Sorting peculiar to particular materials or adapted to a specific purpose may be covered in other classes, see for example the non-exhaustive list of places for special adaptions in the following subsection.
