CPC Definition - Subclass F42D
This place covers:
This subclass covers devices and methods for blasting for both civilian and military applications. The documentation is also organised according to the particular blasting operations. Further it includes particular safety arrangements for blasting or detonations.
C06B : Chemical aspects of explosives, explosive compositions
C06C:Chemical aspects of primers and detonators
Attention is drawn to the following places, which may be of interest for search:
For obtaining fluid from wells | |
For mining or quarring | |
For making tunnels or galleries | |
Seismic investigation using explosives |
This place covers:
Devices and methods for blasting, including the arrangement of blasting cartridges as the smallest explosive unit into assemblies, pyrotechnic, electric and electronic ignition arrangements, in particular for the timed ignition of a multitude of single blasting units, and methods and apparatus for the tamping or loading of explosives. Further includes set-ups for breaching of doors or walls.

Attention is drawn to the following places, which may be of interest for search:
Generating seismic energy using explosive charges |
This place covers:
Methods and devices for increasing the safety of blasting operation, e.g. during blasting operation by providing a physical detonation wave absorbing shield, or the identification, neutralisation and removal of explosives in cases where the explosive did not detonate (abort of operation, malfunction/dud or decommissioning).
This place does not cover:
Fitting or extracting primers in or from fuzes or charges | |
Dismantling fuzes, cartridges, projectiles, missiles, rockets or bombs | |
Explosion or fire protection arrangements on packages or ammunition | |
Packages or ammunition having valves for pressure-equalising; Packages or ammunition having plugs for pressure release, e.g. meltable |
Attention is drawn to the following places, which may be of interest for search:
Elimination of undesirable or temporary components of an intermediate or finished product, e.g. making porous or low density products, purifying, stabilising, drying; Deactivating; Reclaiming |
This place covers:
This group includes all means to avoid the propagation of the detonation or blast wave during the destruction of ammunition by controlled detonation in a pressure chamber which is able to withstand a detonation inside. Also includes detonation wave guiding means.
This place does not cover:
Dismantling fuzes, cartridges, projectiles, missiles, rockets or bombs by combustion |
