Koenen Steel Tube test

6 mm Orifice Plate

Test	Time(s)	Observations
1	64	An orange flame was observed from the orifice
	72	The flame increased in size. Burning test material ran down the side of the tube.

Conclusion

The registered substance has been determined not to have explosive properties.

Interpretation of results:

GHS criteria not met

Conclusions:

3-(Trimethoxysilyl)propyl acrylate was determined not to have explosive properties based on a relevant test method and in compliance with GLP. The result is considered to be reliable.

Description of key information

Explosiveness: Not explosive (EU Method A.14)

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

A measured explosivity study is available for the substance. A negative result for explosive properties by thermal and mechanical (heat and shock) sensitivity was demonstrated in a reliable study conducted according to EU Method A.14 and in compliance with GLP. Under the conditions of the study, the substance is not considered explosive. Sensitivity to friction was not tested as the substance is a liquid.

Justification for classification or non-classification

The substance is not classified for explosivity in accordance with Regulation (EC) No. 1272/2008 because negative results were obtained for the submission substance under the conditions of EU Method A.14.
