Remarks on result:
negative (not further specified)
Remarks:
Thermal sensitivity (effect of a flame)- no explosion
Parameter:
sensitiveness to friction: friction load (N)
Remarks on result:
negative (not further specified)
Remarks:
Mechanical sensitivity (friction)- no explosion

Thermalsensitivity (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:
FAT 45'176/A was evaluated as non-explosive.
Executive summary:

The determination of the physico-chemical data was based on the EU A.14 method This method or tests comprise three parts:

- a test of thermal sensitivity using steel shell.

- a test of mechanical sensitivity with respect to shock using falling hammer.

- a test of mechanical sensitivity with respect to friction using friction tester.

 

Negative results were observed in three tests.

 

So, in conclusion, FAT 45'176/A was evaluated as non-explosive.

Description of key information

Reactive Orange 136 was evaluated as non-explosive.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

The determination of the physico-chemical data was based on the EU A.14 method This method or tests comprise three parts:

- a test of thermal sensitivity using steel shell.

- a test of mechanical sensitivity with respect to shock using falling hammer.

- a test of mechanical sensitivity with respect to friction using friction tester.

 

Negative results were observed in three tests.

 

So, in conclusion, FAT 45'176/A was evaluated as non-explosive.

Justification for classification or non-classification

As the Reactive Orange 136 has been considered to be non-explosive based on the expert statement, hence does not warrant classification according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
