explosive properties of explosives
Type of information:
experimental study
Adequacy of study:
key study
Study period:
from 10 October 2008 to 21 November 2008
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Reason / purpose:
reference to same study
Qualifier:
according to
Guideline:
EU Method A.14 (Explosive properties)

Remarks on result:
not sensitive to impact using an impact energy of 40 J
Key result
Parameter:
sensitiveness to friction: friction load (N)
Remarks on result:
not sensitive to friction using a friction load of 360 N

Cerium ammonium nitrate has been determined not to have shock sensitivity to explosion under the conditions of the test; no ignition or explosion was observed.

Cerium ammonium nitrate has been determined not to have friction sensitivity to explosion under the conditions of the test; no ignition or explosion was observed.

Cerium ammonium nitrate has been determined not to have thermal sensitivity to explosion under the conditions of the test. The test item burned first with a little orange flame, then with a light flame.

Interpretation of results:
GHS criteria not met
Conclusions:
Based under the conditions of the test, cerium ammonium nitrate was observed not to have explosive properties after a shock test, friction test and thermal sensitivity test.

Description of key information

Cerium ammonium nitrate was concluded not to have explosive properties following a GLP study according to test method EC A.14 (Vibert, 2008).

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

The experimental data show that cerium ammonium nitrate is not sensitive to friction, shock or heat.

Justification for classification or non-classification

Based on a GLP study in accordance with EC A.14, cerium ammonium nitrate was concluded not to have explosive properties (Vibert, 2008).
