Endpoint:
explosiveness, other
Type of information:
experimental study
Adequacy of study:
key study
Study period:
March - April 2016
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
Qualifier:
equivalent or similar to
Guideline:
EU Method A.14 (Explosive properties)
Deviations:
yes
Remarks:
slightly other test methods, no thermal sensitivity
Principles of method if other than guideline:
The test substance was tested for mechanical sensitivity (shock and friction). The principles of the test methods including their deviations to the guideline are described in detail in the IUCLID field "any other information on materials and methods".
GLP compliance:

Parameter:
sensitiveness to impact: impact energy (J)

Parameter:
sensitiveness to friction: friction load (N)

Method:
other: not determined
Parameter:
other: not determined
Result:
other: not determined
Remarks on result:
other: The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive porperites

Mechanical sensitivity (friction): No scorch marks on the clay plate or the wooden lag and changes in the substance were observed in all six tests.

Mechanical sensitivity (shock): No scorch marks on the driving band or the underlayment and no change of the substance at any sample were observed.

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive porperites

Interpretation of results:
GHS criteria not met
Conclusions:
The two tests for mechanical sensitivity to friction and shock showed no explosive properties of 2,3-Dichlorobenzonitrile.The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive porperites
Executive summary:

The study was conducted according to a slightly different method than guideline A.14 and investigated the mechanical sensitivity to friction and shock of 2,3 -Dichlorobenzonitrile. The thermal sensivity was not investigated. The results show no explosive properties of 2,3 -Dichlorobenzonitrile as the test substance is not sensitive to shock and friction.

The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive porperites

Description of key information

The study was conducted according to a slightly different method than guideline A.14 and investigated the mechanical sensitivity to friction and shock of 2,3 -Dichlorobenzonitrile. The thermal sensivity was not investigated. The results show no explosive properties of 2,3 -Dichlorobenzonitrile as the test substance is not sensitive to shock and friction.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

The study was conducted according to a slightly different method than guideline A.14 and investigated the mechanical sensitivity to friction and shock of 2,3 -Dichlorobenzonitrile. The thermal sensivity was not investigated. The results show no explosive properties of 2,3 -Dichlorobenzonitrile as the test substance is not sensitive to shock and friction. The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive porperites Thereforefore 2,3 -Dichlorobenzonitrile was classified as "non explosive".
