Table 1: Thermal sensitivity

	T1 (seconds)	T2 (seconds)	Observations
6 mm orifice
Test 1	74	300	Yellow flame
Test 2	71	300	Yellow flame
Test 3	76	300	Yellow flame
2 mm orifice
Test 1	49	300	Yellow flame
Test 2	87	300	Yellow flame
Test 3	56	300	Yellow flame

T1 = time from start of the test to flame from nozzle

T2 = time from start of test to explosion, or end of test (300 seconds)

D = no sign of ignition or explosion but slight decomposition indicated by dark mark on porcelain plate.

Interpretation of results:

GHS criteria not met

Conclusions:

Under the conditions of the test, the test material was determined to be non-explosive.

Executive summary:

The explosivity of the test material was determined using thermal sensitivity and mechanical sensitivity tests (shock, friction) in a study performed under GLP conditions and in accordance with the standardised guidelines EU method A.14.

A Koenen test apparatus was used for determination of sensitivity to heat (flame), a fall hammer for determination of sensitivity to shock and a friction test apparatus for determination of sensitivity to friction. Under the conditions of the test no evidence of explosivity were observed. The test material is non-explosive.

Key value for chemical safety assessment

Explosiveness:

non explosive

Additional information

The explosivity of the test material was determined using thermal sensitivity and mechanical sensitivity tests (shock, friction) in a study performed under GLP conditions and in accordance with the standardised guidelines EU method A.14. The study was assigned a reliability score of 1, reliable without restrictions, in line with the principles of Klimisch et al. (1997).

A Koenen test apparatus was used for determination of sensitivity to heat (flame), a fall hammer for determination of sensitivity to shock and a friction test apparatus for determination of sensitivity to friction. Under the conditions of the test no evidence of explosivity were observed. The test material is non-explosive.

Justification for classification or non-classification

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No. 1272/2008, the substance does not require classification with respect to explosivity.
