Temperature determines whether or not the liquid in a vessel will boil when depressurized. The liquid will not boil if its temperature is below the boiling point at ambient pressure. If the liquid s temperature is above the superheat-limit temperature Tj] (Tsi = 0.897 ), it will boil explosively (BLEVE) when depressurized. Between these temperatures, the liquid will boil violently, but probably not rapidly enough to generate significant blast waves. However, this is not certain, so it is conservative to t sume that explosive boiling will occur (see Section 6.3.2). [Pg.203]

Explosion temperatures were determined for a wide range of combustible liquid and solid organic materials sealed into glass tubes with potassium perchlorate. The lowest temperatures were shown by mixtures with ethylene glycol (240°), cotton Enters (245°) and furfural (270°C). [Pg.1379]

B. Those testing the behavior of materials exposed to high temperatures in the absence of an open flame. These tests are used to determine so-called ignition or explosion temperatures. Ignition or explosion temperature is an indefinite quantity since its evaluation depends strongly on the conditions of measurement. As an example of this variability and dependence on test conditions, the explosion temperatures for as standard an explosive as TNT are quoted from 290 to 570° (Ref 16)... [Pg.289]

One of the most reproducible of these tests is described under Explosion Temperature Test, an official test at Picatinny Arsenal (Ref 15). This test is applicable to the determination of ignition point, decomposition point, deflagration point etc for those explosives which do not really explode under conditions of the test... [Pg.290]

Explosion (Detonation, Deflagration or Ignition) Temperature, It is the temperature at which an explosive, propellant or pyrotechnic composition explodes, detonates, deflagrates or ignites within a definite time, say 0.1t 1-0 or 5.0 seconds. Various methods for its determination arebriefly described in Vol 1, p XVI under Ignition (or Explosion) Temperature Tests... [Pg.309]

For purposes of this calculation, latent heats at constant volume and at constant pressure are assumed equal, heat capacities at constant pressure and at constant volume are assumed equal for solids and liquids [See also Calculation of Temperature of Detonation (and Explosion) 1 and Experimental Determination of Temperature of Detonation [and Explosion) , under Detonation (and Explosion) Temperature Developed On in Vol 4 of Encycl, pp D589 L to D601-R]...

Physical compatibility is also important, as components of explosive formulations are required to mix intimately to produce desirable physical properties. There should be no separation of the components over a period of time nor exudation of any component. The physical properties of an explosive formulation determine firstly the response of ingredients to changes in temperature, which may also include thermal cycling (exposure to hot and cold temperatures in succession over a short period of time) and secondly, they determine the resistance of the...

A comparative evaluation of heat sensitivity of different explosives can be obtained by determining (a) explosion delay (TD) or induction period (b) explosion temperature ( T) and (c) activation energy ( a) which are related to each other. [Pg.180]

Explosion Temperature The explosion temperature is a qualitative term and depends upon several factors, similar to explosion delay. It is measured mainly for a comparative study. In the present work, it is defined as the temperature necessary to cause explosion in exactly 10 or 5 seconds, that is, 10-/5-second time-to-explosion while determining explosion delay with a few milligrams of an explosive.
