Descriptions for B23P and notes/indexes are displayed on this screen.


Note(s)
    This subclass covers:[2015.01]
      combinations of work-modifying operations covered by different subclasses of classes B21-B24;—combinations of metal-working operations with non-mechanical treatments of metal not provided for elsewhere, for example in C21D, C22C, C22F or C23 
    This subclass does not cover
      non-mechanical operations on non-metallic materials unless such operations are explicitly mentioned in this subclass;subsidiary operations performed in conjunction with main operations covered by a single subclass, e.g. assembling of parts as an essential feature of a following metal-working operation, since they are not regarded as operations per se 
    Attention is drawn to the Notes following the title of class B23.
