The test substance is not explosive when exposed to thermal stress or mechanical stress by shock.

Explosiveness of MPKO was determined through thermal sensitivity and mechanical sensitivity (shock or friction). With regard to thermal sensitivity, none of the tests resulting in an explosion or vigorous reaction. None of the tubes showed a deformation or had burst into fragments. The test substance is not explosive when exposure to thermal stress.

A 10 kg mass was dropped from 0.4 m 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 stress by shock. The test substance is not explosive when exposed to mechanical stress by shock.

Interpretation of results:

other: No positive results were obtained, 2-pentanone oxime should be considered to present no danger of explosion.

Reference 2

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 the substance contains chemical groups associated with explosive properties which include oxygen, but the calculated oxygen balance is less than - 200

Description of key information

Non explosive.

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

The calculated oxygen balance is less than -200. In a test according to EU Method A.14 the substance was found to be not explosive when exposed to thermal stress or mechanical stress (shock, friction).

Justification for classification or non-classification

The available data on explosive properties of the test substance do not meet the criteria for classification according to Regulation (EC) 1272/2008 and are therefore conclusive but not sufficient for classification: Based on the chemical structure the substance is not explosive.
