In the Trauzl-block test the expl is loaded into a Pb block at a loading d near 1.0g/cc and stemmed or sealed in with a screw cap. Theoretically these measurements should correlate well with practical conditions because initial and final states in the measurement and in practice should be similar. Unfortunately the Trauzl method is not very reproducible (in part because of rupture of portions of the block by reflected shocks). Consequently no further discussion of the Trauzl-block measurements will be made in this article. Interested readers are referred to Vol 2, B266—95 and Ref 5 for Trauzl block data for many expls...

The ballistic mortar and lead block tests use only small amounts of explosive and are not applicable to slurry explosives which are too insensitive to detonate properly under such conditions. For these explosives it is useful to fire larger amounts of several kg under water and measure the period of oscillation of the gas bubble produced. The longer the period the greater the energy of the gas bubble and this part of the total energy of the explosive has been found to correlate well with the blasting effect of the explosive. [Pg.64]

Lead block tests show this to be a feeble explosive, it is not impact sensitive but shows some decomposition on friction. [Pg.793]

The isolated solid is a very shock- and friction-sensitive explosive [1], but the preparation and safe handling of dilute solutions in solvents other than ether have been described [2], The need to use appropriate techniques and precautions when using iodine azide as a reagent is stressed [3], The purer the more explosive explosive properties are characterised (lead-block test, etc.) in a footnote to [4],...

In the other type of test, the strength of the detonation (explosive power) is determined. Examples of methods for this type of test are the lead block test [139] and the ballistic mortar test [141]. Only the first type of test, which determines the possibility of a detonation, is discussed here. [Pg.78]

In a study of the effect of heat treatment upon the durability of spruce and larch heated at 200 °C in a vacuum, both spruce and larch exhibited good resistance to decay by G. trabeum, but treated spruce exhibited a decay mass loss of 9 % compared to 1 % with larch against C. puteana in an 8-week mini soil block test (Rep etal, 2004).

Concerning brisance and impetus, L H (Ref 1, pp 421-22 Ref 2, p 267) suggest that whether the lead block test is a measure of impetus or of an uncertain combination of impetus and brisance, while a subject of contention, is not of great importance in view of the tendency of impetus and brisance to vary concomitantly. They consider, however, that it is probably safer to use the ballistic mortar values in direct comparison of available energy... [Pg.150]
