R. Meyer J. Köhler A. Homburg Explosives

43 Bullet-resistant
Bulldoze
Auflegeladung; pétardage
A mud covered or unconfined explosive charge fired in contact with a
rock surface without the use of a bore hole. Synonymous with Adobe
Charge and W Mud Cap.
Bullet Hit Squib
Filmeffektzünder; Squib
Bullet hit Squibs are used in motion pictures and television to simulate
ballistic impact of fired projectiles.
What is refered to here are small, pyrotechnic, electrical devices with
varying charges and containing several milligrams of a compound
consisting of W Lead Azide, W Lead Styphnate, W Diazodinitrophenol
and Tetrazole Derivatives.
The initiating explosive material must be specially treated and phlegmatized
to avoid the undesired byproduct of smoke and flash. One
method achieves this by using an admixture of alkaline earth sulfates
or by means of micro-encapsulation of the explosive crystals.
These special electrical igniters are produced by the company J.
Köhler Pyrotechnik in Schardenberg/Austria (www.pyrochemie.at).
Bullet-resistant
Kugelsicher; résistant au balles
Magazine walls or doors of construction resistant to penetration of a
bullet of 150-grain M2 ball ammunition having a nominal muzzle
velocity of 2700 feet per second fired from a .30 caliber rifle from a
distance of 100 feet perpendicular to the wall or door.
When a magazine ceiling or roof is required to be Bullet-Resistant, the
ceiling or roof shall be constructed of materials comparable to the side
walls or of other materials which will withstand penetration of the bullet
above described when fired at an angle of 45 degrees from the
perpendicular.
Tests to determine bullet resistance shall be conducted on test boards
or empty magazines which shall resist penetration of 5 out of 5 shots
placed independently of each other in an area at least 3 feet by 3 feet.
If hardwood or softwood is used, the water content of the wood must
not exceed 15%.
