QUESTION: Detonation Velocity
dizum
there is no (or almost no) explosives with detonation velocity above 10,000
m/s.
He was mentioning "Trauzl test" - explosion in the lead block. Never heard
of that.
So I have a question. Is there any explosive with detonation velocity above
10,000 m/s?
Would somebody provide information or link?
Thank you.

TNN with velocity of 9 600 m/sec is going to be hard to beat!
Herr Trauzel's lead block test has little to do with det. vel. It is — one method of measuring
the power of an explosive.

CHAPTER XXII
APPARATUS FOR THE EXAMINATION OF EXPLOSIVES
III POWER GAUGES
D. TRAUZL'S LEAD BLOCK TEST.
In 1877 Captain Dr. Beckerhinn had already tried detonating, explosives in a
perfectly uniform medium in order to obtain an idea both of the force of an
explosion, and the shape of the cavity produced by it. For this purpose be
compressed regularly piled paper sheets to a packet of 6 inches in height, in
such a way that they formed a homogeneous medium, and drilled cavities in it to
receive the charge and fuse. Beckerhinn also effected explosions in lead, plastic
clay, and hard and soft wood, but obtained less favourable results with these
materials.
Later Mr. Isidore Trauzl resuscitated this ideal and by using a suitable form of
lead cylinders, and indicating an easy manner of charging, was able to place at
the disposal of experimenters the very practical apparatus which is now
generally used.
Lead blocks 200 millimeters (about 8 inches) diameter and of the same height
are cast in an iron mould, the construction of which is shown in Figs. 315 and
316. Along the axis there is a cylindrical cavity 20 millimeters (about 3/4 inch) in
diameter and 110 millimeters (about 4 3/8 inches) deep. The mould is made
easily, and by overturning the bottom part it falls out from the iron core piece for
forming the central hole. Exactly 20 grammes of the explosive are placed in the
cavity, a detonator and fuse are inserted, the bore filled with dry sand, and the
charge fired. Theoretically, a spherical cavity ought to be produced by the
explosion, but as some gases escape through the channel left by, the fuse, and
as the resistance of the tamping is less than that of the lead, the actual cavity
produced is pear-shaped (shown in Fig. 317 by the dotted line). The volume of
this cavity, which is measured by filling it with water from a graduated vessel, is a
measure of the strength of the explosive. As the hardness of lead varies, and is
increased by re-melting, it is advisable to keep in stock a number of lead blocks
cast at one melting, and when trying an explosive to make a trial with the
standard one it is to be compared with-usually kieselguhr dynamite containing 75
per cent. of nitro-glycerin. If this be done, very reliable results will be obtained.
Although this apparatus and Guttmann's [Power Gauge /djh/] give very
valuable assistance in judging explosives, the reader is warned against relying
upon them entirely for drawing absolute conclusions as to, the suitability of
various explosives for any specific purpose. The circumstances attending
blasting operations in rock vary so much, and the requirements are so various in
different places, that a decisive opinion can only be formed by a trial extending
over several weeks, made in precisely equal workings, and after careful
calculation and 'consideration of all the advantages and disadvantages.
----------
MEDINA has a lead block value of 210% (TNT = 100).

Now I have more questions:
*What is TNN? (TNN with velocity of 9 600 m/sec is going to be hard to
beat!)
*What is MEDINA?
Thank you very much.

CHAPTER XXX
POWER AND VIOLENCE OF EXPLOSION
[Figures are the same as in Colver. /djh/]
Trauzl's lead block test affords a ready means of ascertaining the approximate
relative strength of explosives. It consists in firing a charge of the explosive in a
hole in a block of lead and measuring the size of the cavity formed. At the Fifth
International Congress of Applied Chemistry, held at Berlin in 1903, standard
conditions were laid down for carrying out the test :
" The lead cylinder is 200 mm. in height and 200 mm. in diameter. In its axis is a
hole 125 mm. deep and 25 min. in diameter to take the charge. The purest
refined soft lead should be used, and for comparative trials the cylinders should
all be from one melting. The sketch (Fig. 92) shows a convenient form of mould
for casting the blocks. In order to pre-heat the mould, a red-hot ring is placed
round it.
" The Process. The blocks should be allowed to stand after casting sufficiently
long to attain a uniform temperature of 15o to 20o. Ten g. of the explosive are
weighed out and wrapped in a piece of tin-foil, of 80 to 100 g. per sq. metre, of
the dimensions shown at the bottom of Fig. 92, so as to form a cartridge of 25
mm. diameter. An electric detonator containing a charge of 2 g. is inserted into
the centre of the cartridge. The cartridge is carefully pressed home with a
wooden rod keeping the wires central. For tamping, sharp dry quartz sand is
used, which passes through a sieve of 144 meshes per sq. cm. (30 meshes to
the inch), the wire being 0-35 mm. thick. The sand is run in until the hole is full,
and the excess is removed. The charge is then fired electrically. Afterwards the
lead block is inverted and any residue is removed with a brush. The quantity of
water is then ascertained that is required exactly to fill the cavity. This, less the
original volume of the hole, gives a measure of the power of the explosive. [The
enlargement caused by a detonator alone under the same conditions is also
deducted sometimes.— A.M.]
Interpretation of the Results. (1) Lead block tests can only claim to give
satisfactory comparative results when they are made with the same class of high
explosive. If there be great differences in the speed with which the pressure
develops, the results are no longer comparable.
" (2) Statements as to the strength of explosives should always be based on
at least three determinations.
" (3) The reliability of the test is affected considerably : (a) By the uniformity of
the temperature of the lead at the time of the test. The standard temperature is
15o to 20o C. (b) by the uniformity of the tamping ; (c) by the uniformity of the
test."
The lead block test has the advantage that it imitates fairly closely conditions in a
bore-hole, only unfortunately the charge has to be small. The warning against
using the test for the comparison of explosives with different velocities of
detonation appears to be unnecessarily emphatic, for both Kast [Spreng- und
Zündstoffe, p. 1030.] and Dautriche [Compt. rend., 144, 1907, p. 1032; S.S.,
1907, p. 313.3 Ang.,, 1911, p. 2234.] have found that the results are unaffected
by considerable variations in the density to which explosives are compressed,
although this has a very great influence on the velocity of detonation. In the case
of non-detonating explosives, such as black powder, the test fails, however, as
the tamping is blown Out before the full pressure is developed, or the gases
escape through it, unless a more resistant tamping material be used, such as
Portland cement. Probably the results are affected more by the temperature of
explosion, the lead on the interior surface being eroded by the hot gases. For
this reason aluminium explosives, which produce very high temperatures, give
unduly high results in the lead block. If the lead blocks were weighed before and
after the test, and the results corrected for the quantity of metal eroded away, it
is possible that the figures would be more satisfactory.
Neumann gives the following as typical results with the Trauzl test:
[Ang., 1911, p. 2234]
Nitro-glycerine 540 c.c.
Blasting gelatine 530 c.c.
Gelignite 420 c.c. (65 NIG, 25 NaNO3, 8 W.M.)
Gesteins-Wstfalit 380 c.c. (Ammonium nitrate exp.)
Picric acid 315 c.c.
Trinitro-toluene 290 c.c.
Safety gelatine dynamites 200-300 c.c.
Some of the modern safety explosives have been so far, diluted to meet the
requirements of the gallery tests, however, that they enlarge the cavity less than
200 c.c.
In France the Trauzl test is carried out somewhat differently. [Vennin et
Chesneau, p. 101 ; P. et S,, vol. 15, p. 227.] The dimensions of the lead block
are the same. The explosive is placed carefully in the hole, the height that it
occupies is measured, and the density is calculated. A detonator containing 1.5
g. fulminate is passed through a bark cork 5 mm. thick which fits easily into the
hole in the lead. The detonator should project into the explosive at least 25 mm.
The explosive is tamped with dry sand which passes a mesh of 0.35 mm. and
weighs about 1.300 g. per litre. This is poured without agitation on to the cork.
Tests are carried out to ascertain the charge that produces the same
enlargement as 15 g. of picric acid fired under the same conditions. It is not
necessary to continue the tests until the exact equivalent has been found as the
enlargement V is related to the weight of charge by the formula V = KC (sup) 1.4.
The following are the co-efficients thus obtained, picric acid being taken as 100 :

Black powder, or other non-detonating explosive, is mixed first with a suitable
high explosive.
The Trauzl test in trials at D'Anzin in 1897 gave results in good agreement with
those obtained in the mine. [Vermin et Chesneau, p. 109.]

Kling and Florentin have found that the results are not affected appreciably by
reducing the temperature of the explosive to —80o or even to –190o. [P. et S.,
vol. xvii., 1913, p. 151]
Tests are also carried out in France in the earth in a meadow where the soil is as
uniform as possible and has not been disturbed for many years. [Vennin et
Chesnealu, p. 104: P. et S, vol, XV. p. 229.] Holes are drilled 2 metres apart, 1
metre deep, and 29 mm. in diameter. These are charged with 150 to 200 g. of
the explosive and fired with No. 7 detonators. There should be no projection of
earth. The diameter D and the height H of the cavity formed are measured and
the capacity is calculated from the formula V= 1/6 (pi) D (sup) 2 H. From this the
volume of the original drill hole is deducted and the difference is the measure of
the power of the explosive. The tests are carried out in comparison with a
standard explosive of the same type. The results do not always place the
explosives in the same order as the Trauzl test or as trials carried out in mines
under actual working conditions, as is shown by the following figures obtained at
D'Euville in 1910:

Blocks of concrete 500 mm. in diameter and height are also used some-
Concrete test. times with charges of 5 to 10 g. of explosive. The results obtained
are much the same as those yielded by the Trauzl test, but are not so readily
expressed in figures. [Vennin et Chesneau, p. 105.]
Another appliance, that is used to determine the comparative strcngth Ballistic of
explosives, is the ballistic pendulum. …….

Mate....... you had a short fuse .........but slow burning!<g>
How about HNIW which is the current interest in the military due to
being more powerful than HMX( higher VOD and detonation pressures.)
Short Fuse
half a dozen Bundys. About 20% more powerful than HMX. Did some research
(read quick search) and still no VOD. Your reply was the first I had heard
of it. How about Octanitrocubane? 25% more powerful than HMX.
rba...@hotmail.com
You can find a basic explosive property description from the US
patent 5693794 tittled Caged Polynitramine Compound.
Regarding Octanitrocubane? aw,, forget it....it is just of an
academic and theoritical importance.nothing more!

Surely upon surely the VOD of TNN is not 9600m/s, I know where this
come from but I would think its an error. Maybe they forgot to covvert
it from 9600ft/sec (2926m/s) which sounds about right for its density
(0.9g/cm3).
Does anything beat MEDINA in the trauzel test? I know it can be beat
by other tests but that figure is very high.

Yup. The density appears low ... here is the quote from PATR-2700. vol. 8, N 13
... and its deton vel is from 6470m/sec at d 1.60 to 9600m/sec at d 0.9 g/cc
both at 180o (Ref 30) [Why 180o !]
30 - L. Médard, MP 34, 397 (1952) & CA 49 4293h (1955)
Density of 1.60 would put it in good company : -
Nitromethane/toulene 9300m/sec @ 1.6g/cc
Pentanitrophenyl azide 9210 @ 1.76
Glycoluril 9150 @ 2.01

The explosion removed the windows,
the door and most of the chimney.
It was the sort of thing you expected in
the Street of Alchemists. The neighbours
preferred explosions, which were at least
identifiable and soon over. They were better
than the smells, which crept up on you.

I had a look at the stine equation, I would be inteested in seeing the
original article on it. Is it possible for your to email it to me?
I ran some common HE's through it and recieved:
STINE
explosive= calculated (measured)
TNT= 6848m/s (6930m/s)
PETN= 8374m/s (8260m/s)
TETRYL= 7620m/s (7850m/s)
NM= 6529m/s (6350m/s)
Not bad.
Are you familiar with the equation of Kamlet & Jacobs? requires the
same known values, but also incorporates gas volume and mass which are
easily calculated. Have you tried comparing the Stine values to these?
I plan on doing a few comparisons, but it does take time.
KAMLET & JACOBS
explosive= calculated (measured)
TNT= 6970m/s (6930m/s)
ETN= 8040m/s (????)

Wasn't it Tetranitromethan + Toluene?
Tetranitromethan is much more vile stuff than Nitromethane.
Richard
Boomer
of us found issues with it in Zukas & Walters book; Explosive Effects and Applications,
where it is explained incorrectly, so you get the wrong answer..
Yes I have played with the others, I just found this soooooo much easier for me.
If you are in the USA you can get it from a public library by request, if you have the
original title. Did I post it long ago ?

Perhaps I should have searched the group for Kamlet/Jacobs, since you
have brought it up a number of times before. I agree that Stine (Stein?
you have given both) is a lot faster to do. I also found mention that
stine gave a comparison table to ther formulas, it would be interesting
to see.
Im not in the US, however a journal reference should be fine, as long
as its not too obscure. Please post the full reference.
For others, heres the Journal references to the other VOD formulas.
