Reference

Reference 1

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 is an organic substance or mixture containing chemical groups associated with explosive properties, but the exothermic decomposition energy is less than 500 J/g and the onset of exothermic decomposition is below 500°C

Mechanical Sensitivity (Friction Mill): The test item is not sensitive to friction when tested according to EC Guideline A 14.

Pin pressure: 360 N

Result: Six times negative

The test item is not explosive in the sense of EC Guideline A 14.

Interpretation of results:

GHS criteria not met

Description of key information

There are no chemical groups associated with explosive properties present in the molecule. Furthermore the exothermic decomposition energy determined by Differential Scanning Calorimetry is less than 500 J/g.

Key value for chemical safety assessment

Explosiveness:

non explosive

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 therefore is conclusive but not sufficient for classification: Based on the chemical structure and on the exothermic decomposition energy less than 500 J/g the substance is not explosive.
