key study

Study period:

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

Guideline:

EU Method A.21 (Oxidising Properties (Liquids))

Deviations:

no

GLP compliance:

yes (incl. QA statement)

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.

3	4400
4	4000

Mean	4120

 

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.
