November 6, 2012
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Remarks:
Test method in accordance with EU Method A.21. GLP study.
Qualifier:
according to
Guideline:
EU Method A.21 (Oxidising Properties (Liquids))
Deviations:
no
GLP compliance:
yes (incl. certificate)
Contact with:
powdered cellulose
Duration of test (contact time):
60 s
Key result
Sample tested:
test mixture 1:1
Parameter:
mean pressure rise time
Result:
5 660 ms
Key result
Sample tested:
reference mixture with 65% nitric acid + cellulose (1:1 ratio)
Parameter:
mean pressure rise time
Result:
4 120 ms

The test substance has no oxidizing properties in accordance with test A.21 criteria since the 1:1 mixture, by mass, of the substance and cellulose did not ignite spontaneously, and cellulose exhibited the mean pressure rise time higher than the mean pressure rise time of the 1:1 mixture, by mass, of 65 % (w/w) aqueous nitric(V) acid and cellulose.

The quality criteria was fulfilled. In the series of five trials on a single substance no results should differ by more than 30 % from the arithmetic mean. Results that differ by more than 30 % from the mean, were discarded and the testing repeated.

Interpretation of results:
other: Not classified (CLP Regulation EC no. 1272/2008)
Conclusions:
The test substance was determined to be no oxidizing.
Executive summary:

A test to determine oxidizing properties of liquids was performed according to EU Method A.21. GLP study. The test substance has no oxidizing properties since the 1:1 mixture, by mass, of the substance and cellulose did not ignite spontaneously, and cellulose exhibited the mean pressure rise time higher than the mean pressure rise time of the 1:1 mixture, by mass, of 65 % (w/w) aqueous nitric(V) acid and cellulose.

Description of key information

Key study: EU method A.21. GLP study. The test substance was determined to be no oxidising.

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

Key study: A test to determine oxidizing properties of liquids was performed according to EU Method A.21. GLP study. The test substance has no oxidizing properties since the 1:1 mixture, by mass, of the substance and cellulose did not ignite spontaneously, and cellulose exhibited the mean pressure rise time higher than the mean pressure rise time of the 1:1 mixture, by mass, of 65 % (w/w) aqueous nitric(V) acid and cellulose.

Justification for classification or non-classification

Based on the available experimental data, the test substance was not classified as oxidising in accordance with CLP Regulation (EC) No. 1272/2008.
