Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.14 (Explosive properties)
Deviations:
no
GLP compliance:
yes (incl. certificate)

other: See any other information on materials and metods inc. tables.
Parameter:
other: Explosion or vigorous reaction, deformation or burst into fragments (tubes).
Result:
negative, no violent effect on heating under confinement

Key result
Test series:
other: Mehcanical sensitivity by shock
Method:
other: Fall hammer, See any other information on materials and metods inc. tables.
Parameter:
other: Vigorous reaction equivalent to an explosion (e.g. crepitation, a report, bursting into flames)
Result:
negative, not sensitive to detonative shock
Remarks on result:
other: No visual changes in test substance consistency. No (traces of) vigorous reactions. The test substance does not react under mechanical strees by shock.

Thermal Sensitivity- None of the tests resulted in an explosion or vigorous reaction. None of the tubes showed a deformation or had burst into fragments. The test substance was not explosive when exposed to thermal stress.

Mechanical Sensitivity by shock- A 10 kg mass was dropped from 0.4 meter height on the test substance. In none of the 6 tests this resulted in visual changes in test substance consistency. No (traces of) vigorous reactions were observed. From this it was concluded that the test substance does not react under mechanical strees by shock. The test substance was not explosive when exposed to mechanical stress by shock.

Interpretation of results:
other: Non-explosive based on CLP criteria.
Conclusions:
The test substance was considered to present no danger of explosion.
Executive summary:

The explosive property test was performed in accordance with EEC Method A.14 to determine whether the test item presents a danger of explosion when submitted to the effect of a flame (thermal sensitivity), or to shock (mechanical sensitivity). None of the tests resulted in an explosion or vigorous reaction in the thermal sensitivity test. None of the tubes showed a deforomation or had burst into fragments. In the mechanical sensitivity test by shock, no (traces of) vigorous reactions were observed after droppingn a 10 kg mass from 0.4 meter height on the substance. It was concluded that the substance is not explosive when exposed to thermal stress nor mechanical stress by shock.

Description of key information

The test substance presents no danger of explosion. Similarly, for MPKO, the hydrolysis product of OS1600, the substance presents no danger of explosion.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Key study: The explosive properties of OS-1600 were assessed in a study performed in accordance with EEC Method A.14. The substance presents no danger of explosion when submitted to the effect of a flame (thermal sensitivity), or to shock (mechanical sensitivity), and therefore it was determined to be non-explosive.

Supporting study: The explosive properties of the analogue substance MPKO was assessed in a study performed in accordance with EEC Method A.14. The substance presents no danger of explosion when submitted to the effect of a flame (thermal sensitivity), or to shock (mechanical sensitivity), and therefore it was determined to be non-explosive.

Justification for classification or non-classification

Based on available data, the substance presents no danger of explosion when submitted to the effect of a flame (thermal sensitivity), or to shock (mechanical sensitivity) and therefore, it is not classified in accordance with CLP Regulation (EC) no. 1272/2008.
