 Summary of results during the submission of the test material to thermal stress

Test no.	Orifice of the nozzle plate	Reaction	Explosion
1	2 mm	-	No
2	2 mm	-	No
3	2 mm	-	No
4	2 mm	-	No
5	2 mm	-	No
6	2 mm	-	No

 

Exposing the test substance for 300 s to thermal stress did not result in an explosion. None of the test tubes showed a deformation. It was concluded that the test substance is not explosive when exposed to thermal stress.

 

 Mechanical sensitivity (shock)

 

Summary of results during the submission of the test material to mechanical stress (shock)

Test no.	Reaction	Explosion
1	-	No
2	-	No
3	-	No
4	-	No
5	-	No
6	-	No

 

Exposing the test substance to mechanical stress by shock did not result in any visual changes in the test substance consistency. No traces of a vigorous reaction were observed. It was concluded that the test substance does not react under mechanical stress by shock and therefore is not explosive.

 

An assessment of the chemical composition of the six main components present in the test substances also concluded that the substance does not contain any chemically unstable or highly energetic groups that might lead to an explosion.

Conclusions:

No explosive properties could be determined in a reliable study conducted according to an appropriate test protocol, and in compliance with GLP.

Description of key information

non-explosive

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

No explosive properties could be determined using Thermal sensitivity or Mechanical sensitivity (shock) apparatus according to EU Method A.14. There are no chemical groups associated with explosive properties present in the molecule. Available data for silane substances indicates that this class of substances does not show explosive properties.

Justification for classification or non-classification

The available data on explosivity 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. There are no chemical groups associated with explosive properties present in the molecule. Available data for silane substances indicates that this class of substances does not show explosive properties.
