Note(s)

  1. Devices associated with refrigerating machinery are classified in groups F25D 11/00-F25D 16/00[2009.01]
  2. In this subclass, the following term is used with the meaning indicated:
    • "device" means an enclosed space to be cooled; such devices being associated either with refrigerating machinery, e.g. in a refrigerator, or with other cold sources, e.g. in an ice-box.
  3. Attention is drawn to Note (2) following the title of subclass F24F[5]
