Duration of test (contact time):

Sample tested:

test mixture as specified

Remarks:

67 % (w/w) test material in mixture

Parameter:

mean burning time

Remarks on result:

other: Pile burned only during contact with flame.

Sample tested:

test mixture as specified

Remarks:

50 % (w/w) test material in mixture

Parameter:

mean burning time

Remarks on result:

other: Pile burned ~ 1 min after flame removed; burn rate slower than cellulose.

Sample tested:

test mixture as specified

Remarks:

34 % (w/w) test material in mixture

Parameter:

mean burning time

Remarks on result:

other: Pile burned 2.4 min after flame removed.

Sample tested:

test mixture as specified

Remarks:

0 % (w/w) test material in mixture

Parameter:

mean burning time

Remarks on result:

other: In each of two determinations, cellulose burned 2.3 and 2.2 min after flame removed.

Mixtures of test material and cellulose containing 67 %, 50 %, and 34 % test material (by weight) were ignited with a propane flame.

The 67 % test material mixture burned only during contact with the flame, and the weight loss of the pile after ignition was 2 %. Pure cellulose on the other hand, burned for ~ 2.2 min after the flame was removed, and the average weight loss of the pile after ignition was 39 ± 7 %.

The 50 % test material mixture burned for ~ 1 min after removal of the flame and the pile showed a 1 % weight loss after ignition.

The 34 % test material mixture burned for ~ 2.4 min after removal of the flame and the pile showed a 27 % weight loss after ignition.

Therefore, the presence of test material reduced the extent of combustion of the cellulose/ test material mixtures relative to pure cellulose, and no further testing was warranted.

Based on these results, the test material was not considered to exhibit vigorous oxidizing behaviour as defined in EU Method A.17.

Interpretation of results:

other: not classified according to EU criteria

Conclusions:

Under the conditions of the study, the test material was not considered to exhibit vigorous oxidizing behaviour.

Executive summary:

The oxidising properties of the test material were investigated in a study which was conducted in accordance with the standardised guideline EU Method A.17 and under GLP conditions.

During the study, three mixtures of powdered test material and cellulose were prepared containing 67 %, 50 %, and 34 % test material (by weight). The mixtures were formed into conical piles. When the piles were contacted with a propane flame, the extent of combustion was less than that observed for pure cellulose, as indicated by mass loss of the piles and visual observations. Therefore, the presence of test material reduced the extent of combustion of the cellulose/ test material mixtures relative to pure cellulose, and no further testing was warranted.

Based on these results, the test material was not considered to exhibit vigorous oxidizing behaviour as defined in EU Method A.17.

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.
