Reference
Endpoint:
explosive properties of explosives
Type of information:
experimental study
Adequacy of study:
key study
Study period:
February 10, 2016
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
EU Method A.14 (Explosive properties)
Version / remarks:
1985
GLP compliance:
no
Parameter:
thermal sensitivity - Koenen test: diameter of the orifice plate
Remarks on result:
not thermal sensitive if heated under defined confinement
Parameter:
sensitiveness to impact: impact energy (J)
Remarks on result:
not sensitive to impact using an impact energy of 40 J
Parameter:
sensitiveness to friction: friction load (N)
Remarks on result:
not sensitive to friction using a friction load of 360 N

Thermal sensitivity (effect of a flame)
Tests carried out with the sample using the plate with a 6 mm hole showed the following trend:
- From about 21 seconds enlargement of the flame, generation of white fumes and light rain of fire
- End of these phenomena after about 370 seconds.

- End of the observation after 600 seconds.
The tests with the plate with the 2 mm hole showed similar behavior to that with the plate with the 6 mm hole, apart from a higher intensity of the flame.
In none of the six tests prescribed by method (three with the plate with 6 mm hole and three with the one with 2 mm hole) there has been the breakage of the specimen holder.

Mechanical sensitivity (shock)
The sample with the test substance did not result in an explosion (bursting into flame and/or a report is equivalent to explosion) in six tests with impact energy of 40 J.
The sample is not sensitive to shocks.

Mechanical sensitivity (friction)
The sample did not give rise to an explosion ( rattling a violent ignition or flame are equivalent to explosion) in any of the six tests provided with the load of 360 N.
The sample is not friction sensitive.

Justification for classification or non-classification

Based on the CLP Regulation (EC 1272/2008), substances, mixtures and articles are classified as an unstable explosive on the basis of the flowchart in Figure 2.1.2 of the CLP Regulation. The test methods are described in Part I of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria.

Explosives, which are not classified as an unstable explosive, shall be classified in one of the six divisions based on Test Series 2 to 8 in Part I of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria according to the results of the tests of explosibility, sensitiveness and thermal stability, laid down in Table 2.1.1 of CLP Regulation.

Test substance was evaluated as for the thermal sensitivity and the mechanical sensitivity (with respect to shock and friction). Test results are negative, since no explosion occurred. On these bases, the substance is not classified.
