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
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.
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. 2) In contrast to the EC guideline aluminium foil is used to pack the substance. 3) Ten tests are performed.
GLP compliance:
not specified
Parameter:
other: More sensitive to shock than m-dinitrobenzene
Remarks on result:
negative (not further specified)
Remarks:
If all tests according to Lütolf method are negative, the powder can be considered not shock sensitive as the reference substance meta-dinitrobenzene is not shock sensitive in similar conditions (although not tested simultaneously in this study)

RESULTS:

-10 times negative, not shock sensitive (sensitivity > 39.2 Nm)

Interpretation of results:
non explosive
Conclusions:
The test substance is not shock sensitive (sensitivity > 39.2 Nm).

Description of key information

The substance is considered not explosive because it does not contain any structural groups that are indicative of explosive properties.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

A supporting study (Klimisch 4, Janssen Pharmaceutica Process Safety Center, 2004) is available, indicating that T002488 is not sensitive to impact (shock sensitivity > 39.2 Nm). These results support the conclusion that the substance is not explosive based on the absence of structural groups that are indicative of explosive properties.

Justification for classification or non-classification

T002488 should not be considered explosive based on the absence of structural groups that are indicative of explosive properties. This is also confirmed by the results of a falling hammer test (Lütolf) indicating that the substance is not sensitive to impact (shock sensitivity > 39.2 Nm).
