- Parameter:

- Remarks on result:
- other: In this confirmatory test, observed burning of the mixtures is due to combustion of the test material and not due to the oxidising properties of the test material. The result of the main test has been shown to be false-positive.
- Interpretation of results:
- other: Not classified according to EU criteria.
- Conclusions:
- Under the conditions of this study the test material has been determined not to have oxidising properties.
- Executive summary:
The oxidising properties of the test material were investigated in a study conducted in accordance with the standardised guideline EU Method A.17 under GLP conditions.
In the preliminary test the pile ignited and burnt with an orange flame emitting grey fumes and a small amount of sooty particulates. The entire pile was burnt before the flame self-extinguished.
In the main test the maximum burning rate was shown to be 4.88 mm/s and the maximum burning rate of reference mixtures was 1.34 mm/s. The positive result obtained in the main test was subjected to a confirmatory test by repeating the test using celite in place of cellulose. Celite (diatomaceous earth, also known as kieselguhr) is inert to oxidation. In this confirmatory test, observed burning of the mixtures is due to combustion of the test material and not due to the oxidising properties of the test material. The result of the main test has been shown to be false-positive. Therefore the test material has been classified as non-oxidising, since in the confirmatory test the test material: celite mixtures yielded burning rates to negate the results of the main test.
Under the conditions of this study the test material has been determined not to have oxidising properties.

Discussion
The positive result obtained in the main test was subjected to a confirmatory test by repeating the test using celite in place of cellulose. Celite (diatomaceous earth, also known as kieselguhr) is inert to oxidation. In this confirmatory test, observed burning of the mixtures is due to combustion of the testmaterialand not due to the oxidising properties of the test material.
The result of the main test has been shown to be false-positive. Therefore the test material has been classified as non-oxidising, since in the confirmatory test the test material:celite mixtures yielded burning rates to negate the results of the main test.

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 oxidising properties.
