  2. Gurney equations - Wikipedia

    en.wikipedia.org/wiki/Gurney_equations

    C - The mass of the explosive charge M - The mass of the accelerated shell or sheet of material (usually metal). The shell or sheet is often referred to as the flyer, or flyer plate. V or V m - Velocity of accelerated flyer after explosive detonation N - The mass of a tamper shell or sheet on the other side of the explosive charge, if present

  3. Net explosive quantity - Wikipedia

    en.wikipedia.org/wiki/Net_explosive_quantity

    The net explosive quantity (NEQ), also known as net explosive content (NEC) or net explosive weight (NEW), of a shipment of munitions, fireworks or similar products is the total mass of the contained explosive substances, without the packaging, casings, bullets etc. [1] It also includes the mass of the TNT-equivalent of all contained energetic substances.

  4. Combustibility and flammability - Wikipedia

    en.wikipedia.org/wiki/Combustibility_and...

    The original mass of flammable material and the mass of the oxygen consumed (typically from the surrounding air) equals the mass of the flame products (ash, water, carbon dioxide, and other gases). Lavoisier used the experimental fact that some metals gained mass when they burned to support his ideas (because those chemical reactions capture ...

  5. Oxygen balance - Wikipedia

    en.wikipedia.org/wiki/Oxygen_balance

    An explosive with a negative oxygen balance will lead to incomplete combustion, which commonly produces carbon monoxide, which is a toxic gas. Explosives with negative or positive oxygen balance are commonly mixed with other energetic materials that are either oxygen positive or negative, respectively, to increase the explosive's power.

  7. Explosives shipping classification system - Wikipedia

    en.wikipedia.org/wiki/Explosives_shipping...

    Division 1.1: Explosive that has a mass explosion hazard. A mass explosion is a detonation of almost entire load instantaneously. Division 1.2: Goods and Substances without a mass explosion hazard, but with a projection (shrapnel/fragmentation). Division 1.3: Goods and substances with a mass fire hazard, and a minor, blast and/or projection ...

  8. Flammability diagram - Wikipedia

    en.wikipedia.org/wiki/Flammability_diagram

    Flammability diagram for methane. Flammability diagrams show the control of flammability in mixtures of fuel, oxygen and an inert gas, typically nitrogen.Mixtures of the three gasses are usually depicted in a triangular diagram, known as a ternary plot.

  9. Explosives safety - Wikipedia

    en.wikipedia.org/wiki/Explosives_safety

    Generally, thermal hazards from explosives events are of less concern than blast and fragment hazards. With the release of energy from an explosion is heat. The amount of heat varies with the energetic compound (explosive). All explosives compound molecules are potentially unstable held together with weak bonds in their outer shell.
