Definition of explosive

More speeifie definitions of explosives appear in legislation, e.g. in tlie UK under the Explosives Aet 1875 as amended, whieh eovers ... 

Relevant sections of the Homeland Security Act of 2002 (HSA) [125] and the Safe Explosives Act of that law, which is Tide II of that Act, are presented with applicable definitions of explosives and terrorism. 

The definition of explosion, given by Dunkle (Ref 12) "An explosion is a milder form of detonation , although correct, does not help in definition of detonation. For this reason we are giving here a longer definition as taken from MIL-STD-444 (Ref 5a,... 

Class 1 includes solid and liquid explosives as well as articles which contains explosives, e. g., shells or bombs. The definition of explosives following the dangerous goods classification is different from the definition for explosive following Directive 67/548/EEC. The heading of Class 1 covers ... 

Material Safety Data Sheets, which are now required to be provided by distributors and manufacturers of commercial chemicals, give detailed information on the characteristics of all commonly sold laboratory chemicals. The definitions of explosive, flammable, combustible, and various healthhazards are consistent with those provided by OSHA in CFR 29, Parts Table 3.2 Exemption Limits for a Few Critical Classes of Materials Representing Health Hazards For a Class 4, Hazardous Use Occupancy... 

The technical definition of explosion-proof is taught by the National Fire Protection Association (NFPA) in its Standard No. 70, the National Electrical Code (NEC). In Article 100, the Code offers this general definition of an explosion-proof apparatus ... 

The definitions of explosion hazard and explosion risk are limited even more on account of the specitity of this topic. The paper follows (Die. 

A definition of explosion risk wasn t found in international standards. For this explosion risk is defined by analogy with fire risk. 

Definition of Dust E losion A dust explosion is the rapid combustion of a dust cloud. In a confined or nearly confined space, the explosion is characterized by relatively rapid development of pressure with a flame propagation and the evolution of large quantities of heat and reaction products. The required oxygen for this combustion is mostly supphed oy the combustion air. The condition necessaiy for a dust explosion is a simultaneous presence of a dust cloud of proper concentration in air that will support combustion and a suitable ignition source.

Suppression system design parameters fall into the two categories of explosion threat definition and suppression system hardware definition. The various influences are summarized in Table 26-23. 

This energy measure is equal to Brode s definition of the energy, multiplied by a factor 2. The reason for the multiplication is that the Brode definition applies to free-air burst, while Eq. (6.3.15) is for a surface burst. In a fiee-air burst, explosion energy is spread over twice the volume of air. 

According to Urbanski (Ref 35. p 473) In the second half of the nineteenth century, Picric Acid was very widely used as a fast dye for silk and wool. The first definite suggestions as to the application of Picric Acid for the manufacture of explosives go back to the early second half of the nineteenth century. They referred... 

What do we mean by the rate of a chemical reaction Informally, we consider a reaction to be fast if the products are formed rapidly, as occurs in a precipitation reaction or an explosion (Fig. 13.1). A reaction is slow if the products are formed over a long period of time, as happens in corrosion or the decay of organic material (Fig. 13.2). Our first task is to set up a precise, quantitative definition of the rate of a chemical reaction.
