Description of key information

The test item has not to be classified as oxidising solid, oxidising liquid or oxidising gas.

Key value for chemical safety assessment

Oxidising properties:
non oxidising

Additional information

Oxidising gases


The test item is a solid at ambient conditions. This hazard class is only applicable for gases. Thus, the substance was not considered for classification as oxidising gases.


Oxidising liquids


The test item is a solid at ambient conditions. This hazard class is only applicable for gases. Thus, the substance was not considered for classification as oxidising liquids.


Oxidising solids


BATTELLE 2003a


An experimental study was conducted according to EEC Method A.17 to determine the oxidizing properties of the test item. Therefore, the burning time of different mixtures of test item and cellulose were compared to the burning time of the reference substance barium nitrate mixed with cellulose. As the barium nitrate reference material used had not been pre-ground and as result burnt too slowly when mixed with cellulose. This resulted in a wrong conclusion being made on the oxidizing properties of the test item.


 


BATTELLE 2003b


An experimental study was conducted according to EEC Method A.17 to determine the oxidizing properties of the test item. Therefore, the maximum burning rate of different mixtures of test item and cellulose were compared to the max burning rate of the reference substance barium nitrate mixed with cellulose. The maximum burning rate of test item/cellulose mixture was found for the mixture with 10 % test item and was equal to 0.78 mm/s. This value is lower than the maximum burning rate of barium nitrate (1.05 mm/s for mixture with 60 % barium nitrate). Thus it was concluded that the test item has no oxidizing properties.


 


Based on a weight of evidence approach it is concluded that the test item has no oxidizing properties.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008


Based on available data and taking into account the provisions laid down in Regulation (EC) No 1272/2008 (CLP), as amended for the fifteenth time in Regulation (EU) 2020/1182, and UN GHS Rev 8 (2019) the substance is not considered to be classified for oxidising properties.
