For safety reasons, a preliminary test was carried out to
establish safe conditions for the performance of the definitive test. A
very small sample (about 10 mg) of the test item was subjected to
heating without confinement in a Bunsen flame.
Thermal Sensitivity (Effect of a flame)
The test item was filled into the tube in three equal increments
of about 9 cm3, each increment being gently consolidated by
applying a force of 80 N to the surface. Care was taken to avoid bubbles
Heating was applied at a fixed rate by four standard gas burners
located around the steel tube. The burners were adjusted so that the tip
of the internal blue core of the flame almost touches the tube.
Two series of three tests were performed, the first series using a
nozzle-plate with a hole 6 mm diameter and the second series using a
nozzle-plate with hole of 2 mm diameter.
The three tests with 6 mm diameter orifice plate showed similar
After about 55 s, flame more intense;
After about 72 s intense phase characterized by generation of
smoke. The sample was expelled from the orifice;
End of intense phase after about 200 seconds;
End of all phenomena after about 250 seconds.
The three tests with 2 mm diameter orifice plate showed a similar
behaviour to those with 6 mm diameter orifice plate but with a more
During the six tests performed on the sample,no explosion occurred
during 5 minutes.
The test result is considered negative.
Mechanical Sensitivity (Shock)
The test item in powdered form sieved all that passes through the
sieve mesh 0.5mm was placed in a die device, with a cylindrical measure
of 40 mm3, which was then centred on a steel anvil. Six tests
were performed by dropping a guided 10 kg steel hammer weight from a
height of 0.4 m (40 J) onto the die device containing the sample.
No evidence of ignition, explosion or decomposition was obtained
during the series of six tests at 40 J performed on the sample.
Mechanical Sensitivity (Friction)
An aliquot of 10 mm3of test item sieved all that passes
through the sieve mesh 0.5 mm were placed onto a standard porcelain
plate, and brought into contact with a weighted, standard porcelain peg
by moving the plate, to and fro, over a distance of 10 mm once in 0.44
A series of six tests were performed with a 360 N loading.
No explosion was obtained during the tests (crepitation and/or a
report or bursting into flame are equivalent to explosion).
