Interpretation of results:
GHS criteria not met
Conclusions:
The test substance is not explosive.
Executive summary:

The explosive properties of the substance were determined by a study conducted to EEC Method A14.

A Koenen test apparatus was used for determination of sensitivity to heat (flame), a fall hammer for determination of sensitivity to shock and a friction test apparatus for determination of sensitivity to friction.

The test substance was not explosive in any of the tests.

Description of key information

The explosive properties of the substance were determined by a study conducted to EEC Method A14.

A Koenen test apparatus was used for determination of sensitivity to heat (flame), a fall hammer for determination of sensitivity to shock and a friction test apparatus for determination of sensitivity to friction.

The test substancce was not explosive in any of the tests.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Justification for classification or non-classification

The substane has been determined not to have explosive properties based on the test methods performed and is therefore not classified for explosives.
