Note(s)

This sub-class covers the use of a blast of any particles or pellets dispersed in air, gas, or liquid for the treatment of surfaces, the particles usually being of abrasive material. It also covers the equivalent use of a jet of particles or pellets projected or energised by other means than a stream of air. Accordingly

  1. the word "abrasive" is to be understood as covering any material used in the manner stated;
  2. the word "blast" is to be understood as covering any equivalent jet of material.
