Blasting Switch
Zündschalter; commande de tir; ignition switch
Device which actuates electric primers by using main voltage – in
openpit and potash mining, for example. The switch can be located in
a surface stand(shelter outside a mine) e.g. if the danger of gas
outbursts exists.
Blastmeter
Blastmeters are simple devices which are used to determine the
maximum pressure of a shock wave (W p. 78) They consist of steel
bodies into which holes of different diameters are drilled and convered
with aluminum foil.
The smallest diameter is determinted at whitch the foil covering is
penetrated. The device can be calibrated by static pressure.
Bomb Drop Test
Serves to test the sensitivity of military explosives as bomb fillers.
Bomb drops are made using bombs assembled in the conventional
manner, as for service usage, but containing either inert or simulated
fuzes. The target is usually reinforced concrete.
Boom Powder
A pyrotechnic ignition mixture designed to produce incandescent particles.
A typical boom composition is:
Ingredient Parts

Iron Oxide 50
Titanium (powdered) 32.5
Zirconium (powdered) 17.5
plus about 1 part of cellulose nitrate as a binder.
Booster
Verstärkungsladung; relais
A device to ensure W Initiation. A booster can be a cap-sensitive
