Type of information:
experimental study
Adequacy of study:
key study
Study period:
from 10 Jun 2005 to 13 Oct 2005
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Reason / purpose for cross-reference:
reference to same study
according to guideline
EU Method A.16 (Relative Self-Ignition Temperature for Solids)
Version / remarks:
Cited as Directive 92/69/EEC, A.16
The maximum oven temperature was 300°C instead of 400°C as required by the guideline. A Grewer test was done in addition, in order to confirm the results up to 500°C.
GLP compliance:
Key result
Relative self-ignition temperature:
> 400 °C
Remarks on result:
no self ignition observed under the test conditions
The test item has no auto-ignition temperature up to at least 400°C.
Executive summary:

The determination of the relative self-ignition temperature of cerium trinitrate was performed according to EU Method A16 only up to 300°C with a plateau.
No self-ignition is observed up to
A Grewer test, performed up to
500°C, was done as complement of previous test.
No exothermic reaction is observed up to
500°C. The test item has no auto-ignition temperature up to at least 400°C.

Description of key information

Following a GLP study in accordance with EC test method A.16, cerium trinitrate has no auto-ignition temperature up to at least 400°C (Cerutti, 2005).
