Guideline:

EU Method A.14 (Explosive properties)

Version / remarks:

1992

Deviations:

no

GLP compliance:

yes

Key result

Parameter:

sensitiveness to impact: impact energy (J)

Shock test

Test No.	Weight / kg	Height / m	Results
1	10	0.4	No ignition, no explosion
2	10	0.4	No ignition, no explosion
3	10	0.4	No ignition, no explosion
4	10	0.4	No ignition, no explosion
5	10	0.4	No ignition, no explosion
6	10	0.4	No ignition, no explosion

 

Koenen steel tube test

 

The test item is a very toxic product, so only tests with circular nozzle plate with a central hole of 2 mm were performed.

Hole diameter / mm	Weight / g	T1 / s	T2 / s	Results
6	-	-	-	-
6	-	-	-	-

2	28.854	27	147	Negative
2	28.817	29	118	Negative
2	28.883	30	131	Negative

T1 : time from application of the flame to a noticeable effect from the orifice.

T2 : time from application of the flame to the end of the combustion without recorded event (e.g. explosion) as in these tests or to an explosion.

Interpretation of results:

GHS criteria not met

Conclusions:

The test item is not considered to have explosive properties.

Executive summary:

A study was conducted according to EEC Method A.14. The thermal sensitivity and the mechanical sensitivity to shock was investigated. No explosion was observed under the test conditions. Therefore, the item is not considered to have explosive properties.

Description of key information

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

A study was conducted according to EEC Method A.14. The thermal sensitivity and the mechanical sensitivity to shock was investigated. No explosion was observed under the test conditions. Therefore, the item is not considered to have explosive properties.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
Based on the structure of the molecule and taking into account the provisions laid down in Regulation (EC) No 1272/2008 (CLP), as amended for the seventeenth time in Regulation (EU) 2021/849, the test item does not have to be classified with respect to explosiveness.
