Endpoint:
explosive properties of explosives
Type of information:
experimental study
Adequacy of study:
supporting study
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:
EC Directive 92/69 A.14
GLP compliance:
yes
Parameter:
thermal sensitivity - Koenen test: diameter of the orifice plate
Number of fragments:
0
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:
sensitive to friction
Remarks:
Loading at 360 N; 2 time positive (sparks observed), 4 times negative
Interpretation of results:
other: Sensitive to friction
Conclusions:
During a series of tests, the substance was found to be sensitive to friction (explosive properties seen within mechnical sensivity test). Explosive properties were not seen in the presence of a flame or by the application of mechanical shock.
Endpoint:
explosive properties of explosives
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

Description of key information

In a GLP-compliant, EU method study which assess the explosive properties of the substance using 3 different tests it was determined that the test substance was sensitive to friction (360N load).

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

The key information available concerning explosive properties of the substance does not contain sufficient information to determine classification under the CLP regulation (EU 1272/2008 as amended). It is clear that the substance is not explosive in the presence of flame or by the application of mechanical shock but the results of a supporting study indicate the substance may be sensitive to friction. However, the test methods used (EC methods) are not sufficient to consider classification under CLP where UN Method results are required. Based on the substance structure, there are no chemical groups associated with explosive properties, and the substance has an oxygen balance of < -200 (-257.9), and accordingly would not be considered explosive. The classification for this endpoint is non-explosive.
