yes

Specific details on test material used for the study:

Identity: FAT 40557/A
Batch-no.: PV1
Purity: 65 %
Appearance: Solid powder, red-brown
Expiration date: 30 September, 2002
Storage conditions: At room temperature at about 20 °C, away from direct sunlight

Parameter:

thermal sensitivity - Koenen test: diameter of the orifice plate

Number of fragments:

0

Remarks on result:

not thermal sensitive if heated under defined confinement

Parameter:

sensitiveness to impact: impact energy (J)

Remarks on result:

negative (not further specified)

Parameter:

sensitiveness to friction: friction load (N)

Remarks on result:

negative (not further specified)

Thermal sensitivity (effect of a flame):

The test result was regarded as negative, since no explosion (fragmentation of the tube into three or more pieces) occurred in any of the three individual tests using 6.0 mm or 2.0 mm diameter orifice plates.

 

Mechanical sensitivity (shock):

The test result was regarded as negative, since no explosion (bursting into flame and/or a report is equivalent to explosion) occurred in any of the six individual tests using a drop weight of 10 kg from a drop height of 0.40 m (40 J) in the specified falling hammer apparatus.

 

Mechanical sensitivity (friction):

The test result was regarded as negative, since no explosion (crepitation and/or a report or bursting into flame are equivalent to explosion) occurred in any of the six individual tests using a 360 N loading in the specified friction tester.

Interpretation of results:

GHS criteria not met

Conclusions:

The test substance is not explosive.

Executive summary:

In a GLP-compliant study, performed according to EU method A.14, the explosiveness of the test substance was determined. Experiments were performed six times and results indicate that the substance is not thermally sensitive, shock sensitive, or sensitive to friction. The testing material did not explode under the effect of flame and was not sensitive to shock or friction. Based on the test results, it could be concluded that the test substance is not explosive.

Description of key information

The test substance is not explosive.

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

In a GLP-compliant study, performed according to EU method A.14, the explosiveness of the test substance was determined. Experiments were performed six times and results indicate that the substance is not thermally sensitive, shock sensitive, or sensitive to friction. The testing material did not explode under the effect of flame and was not sensitive to shock or friction. Based on the test results, it could be concluded that the test substance is not explosive.

Justification for classification or non-classification

As the test substance is not explosive, hence does not warrant classification according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
