 B24C
ABRASIVE OR RELATED BLASTING WITH PARTICULATE MATERIAL
 B24C

Note(s)

  1. This subclass covers:
    • the use of a blast of any particles or pellets dispersed in air, gas, or liquid for the treatment of surfaces or cutting of materials, the particles usually being of abrasive material;
    • the equivalent use of a jet of particles or pellets projected or energised by means other than a stream of air.
  2. In this subclass, the following terms are used with the meanings indicated:
    • "abrasive" covers any material used in the manner mentioned in Note (1) above;
    • "blast" covers any equivalent jet of material mentioned in Note (1) above.
