What explosive do we use as the comparison for measuring explosive power?
TNT
What general requirements must material used to manufacture military
explosives meet?
Must be cheap, plentiful, and not vital to any other phase of the war effort
What is the brisance of a military explosive?
The shattering or fragmentation effect
What term describes the tendency of a substance to produce vapors?
Volatility.
When a military explosive does not react with the metal that encases it or with
another explosive, it is said to have what characteristic?
A natural compatibility
What is meant by explosive toxicity?
An explosive's poisonous characteristics
What is hygroscopicity?
The moisture-absorbing property of an explosive.

rapid and sparkling combustion?
Deflagration
What condition is essential for an explosive to detonate rather than to merely
deflagrate?
, It must be confined.

functioning of the explosive train?
Primer
What are the two means by which we can activate a detonator?
The action of a primer or by a non-explosive impulse.
What is the purpose of a delay in an explosive train?
A delay controls the timed delay in the functioning of the train
What does an explosive booster do?
Amplifies the detonation received from the detonator to detonate the main
charge

fragmentation?
Blast
What effect causes greater penetration of the explosive charge?
Munroe effect.
What happens when you increase the standoff distance of an explosive?
Its penetrating capability is increased
