Special rules of classification

For applications which deal with polymer compositions comprising inorganic additives, where it is not apparent, whether the invention resides in the polymeric or the inorganic component, the application should be classified in the relevant subgroups of both the inorganic additive and the polymeric component.

Insulating materials comprising compositions of different organic insulating materials are classified in each relevant subgroup (e.g. an insulating layer comprising a polyethylene and a polystyrene is classified in both H01B 3/441 and H01B 3/442).

Groups H01B 3/18, H01B 3/30, H01B 3/42, H01B 3/44 are only used when no relevant subgroup is available

The group H01B 3/30 is used for insulating materials characterized by predominantly by physical properties
