Notes[n] E02D:
  • This subclass covers underground structures made by foundation engineering, i.e. involving disturbance of the ground surface.  
  • This subclass does not cover underground spaces, made by underground mining methods only, i.e. not involving disturbance of the ground surface, which are covered by subclass E21D .  
E02F DREDGING; SOIL-SHIFTING (winning peat E21C 49/00).
Notes[n] E02F:
  • This subclass covers :
    • primarily equipment for excavating or loosening earth or for moving loose earth;
    • equipment for working similarly on other materials and similar equipment for loading or unloading materials.
