Reference
Endpoint:
explosiveness, other
Type of information:
experimental study
Adequacy of study:
key study
Study period:
June 1996
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
test procedure in accordance with national standard methods with acceptable restrictions
Remarks:
Test methods are described in a separate document.
Qualifier:
no guideline followed
Principles of method if other than guideline:
The test methods are described in another document. This does not impair the conclusion of the test results. The thermal sensitivity is not investigated within this study. The principles of the test methods including their deviations to the guideline are described in detail in the field "any other information on materials and methods".
GLP compliance:
not specified
Parameter:
other: More sensitive to shock than m-dinitrobenzene
Remarks:
migrated information
Remarks on result:
not measured/tested
Parameter:
other: More sensitive to friction than m-dinitrobenzene
Remarks:
migrated information
Remarks on result:
not measured/tested
Parameter:
other: Explosive (not specified)
Remarks:
migrated information
Remarks on result:
negative (not further specified)
Remarks:
with respect to mechanical sensivity (shock)

Tests regarding the mechanical sensitivity (shock) was negativ. 4 -tert-Butylbenzonitrile was found to be not sensitive to shock.

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
4-tert-Butylbenzonitrile is not sensitive to shock (mechanical sensitivity).
Executive summary:

The study investigates the mechanical sensitivity of 4 -tert-Butylbenzonitrile (the sensitivity to shock).

The test method is very similar to those of guideline A.14 and is described in another document. This fact does not impair the conclusion of the negative test result. 4 -tert-Butylbenzonitril is not sensitive to shock. The thermal sensitivity was not investigated within this study.

Description of key information

4-tert-Butylbenzonitrile is not sensitive to shock (mechanical sensitivity).

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

A investigates the mechanical sensitivity of 4 -tert-Butylbenzonitrile (the sensitivity to shock).

The test method is very similar to those of guideline A.14 and is described in another document. This fact does not impair the conclusion of the negative test result. 4 -tert-Butylbenzonitril is not sensitive to shock. The thermal sensitivity was not investigated within this study.

Justification for classification or non-classification

According to these findings 4 -tert-Butylbenzonitrile is considered to be not an explosive and does not have to be classified.
