The sample did not exhibit an explosion during any of the tests. The test result is therefore considered Negative.

MECHANICAL SENSITIVITY (SHOCK)

mass of drop hammer: 10 kg

dropping height: 40 cm

In each test from 1 to 6 the result was negative, no explosion occured during the test.

MECHANICAL SENSITIVITY (FRICTION)

Loading: 360 N

In each test from 1 to 6 the result was negative, no explosion occured during the test.

Interpretation of results:
GHS criteria not met
Conclusions:
The test item is not thermally sensitive, not shock sensitive and not sensitive to friction.
Endpoint:
explosive properties of explosives
Type of information:
experimental study
Adequacy of study:
supporting study
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
other: The test is performed according to EC guideline with some small deviations. However, there is no information on purity of the substance.
Reason / purpose:
reference to other study
Qualifier:
according to
Guideline:
EU Method A.14 (Explosive properties)
Deviations:
yes
Remarks:
1)The weight of the falling hammer is 5 kg and dropped from 0.8 m, however, the energy applied is the same as guideline, 40 J or 40 Nm.
GLP compliance:
not specified
Specific details on test material used for the study:
- Name of test material (as cited in study report): 4-nitrobenzenesulfonylchloride
Parameter:
sensitiveness to impact: impact energy (J)
Remarks on result:
negative (not further specified)
Remarks:
For the BAM falling hammer test, the substance is considered to present an explosion hazard in the sense of the EC directive, if an explosion (bursting into flame and/or a report is equivalent to explosion) occurs at least once in six tests.

RESULT: 6 times negative (sensitivity >39.2)

Interpretation of results:
GHS criteria not met
Conclusions:
The test substance is not shock sensitive.

Description of key information

From a key study (K1, Younis, 2017) according to the EC A.14 guideline it could be concluded that the test item is not thermally sensitive, not shock sensitive and not sensitive to friction and therefore should not be considered an explosive substance.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

A supporting study (K4, PSC, 2006) confirms that the test item is not shock sensitive.

Justification for classification or non-classification

The test item is not thermally sensitive, not shock sensitive and not sensitive to friction according to the EC A.14 guideline and therefore should not be considered an explosive substance.
