Note

In this subclass, it is desirable to add the indexing codes of subclass C12R. The indexing codes should be linked. [6]

Pasteurisation, sterilisation, preservation, purification, clarification, or ageing of alcoholic beverages

combined with removal of precipitate or added materials, e.g. adsorption material

with the aid of ion-exchange material or inert clarification material, e.g. adsorption material

044
