Volume Strength
The volume can be determinated experimentally by test explosion in
the W Bichel Bomb.
Volume Strength
Same as Cartridge Strength or W Bulk Strength. Also W Weight
Strength and W Strength.

Trade name of a W ANFO explosives marketed in Germany by WA-
SAG-CHEMIE.
Water-driven Injector Transport
Emulsionsförderung; transport par injection d’eau
The liquid nitrate esters – nitroglycerine and nitroglycol – are highly
sensitive to impact; handling of these substances in the factory in free
unbound condition is dangerous. They are conveyed in the form of
emulsions: the explosive oil is sucked up by means of a compressedwater-driven
injector, and the emulsion sent through conduit pipes for
processing (mixing houses). It is then separated from the carrier water
and, if required, is dried by passing through a salt filter.

Water Resistance
Wasserfestigkeit; résistance a l’eau
In the USA the following method is employed for testing the water
resistance of commercial explosives:
Sixteen regularly spaced holes (about 6 mm P) are cut in the cartridge
paper (30 mm in diameter, 200 mm long) of the explosive to be tested,
and the flaps on the front faces are sealed with tallow. The cartridges
thus prepared are placed in a flat, porcelaincoated dish covered with a
thin layer of sand, and water at 17–25 °C (63–77 °F) is poured over
the sand layer up to a height of about 25 mm. The cartridges are left
under water for a certain period of time, are then taken out, the seal is
