Notes

(1)Electrolytic or electrophoretic processes or apparatus or operational features are classified

 (i)in the groups for the compounds or articles produced, and

 (ii)in the groups which cover the apparatus or operational features.  [2]

(2)The electrolytic or electrophoretic purification of materials is classified according to the nature of the liquid in the relevant places, e.g. A01K 63/00, C02F 1/46, C25B 15/08, C25D 21/16, C25F 7/02.  [2]
