Description of key information

The highest burning rate was observed for a test item/cellulose-mixtures with 10 % test item. The burning rate of this mixture was significantely lower then the burning rate of the referance mixture. 
Therefore Slags, ferronickel-manufg./Electric Furnace Slag / Converter Slag is not considered to be an oxidizing substance.

Key value for chemical safety assessment

Oxidising properties:
no

Additional information

A study on the oxidising properties of Slags, ferronickel-manufg./Electric Furnace Slag / Converter Slag was conducted according to the principles of EEC Directive 440/2008, guideline A.17. Determination of any oxidising properties of the substance is necessary for the characterisation of the substance and its chemical safety assessment according to REACH Regulation.

The substance was tested through a preliminary and a main test. The preliminary test examined the oxidising properties of a mixture of substance and powdered cellulose in a 2:1 respective ratio. No rigorous reaction was observed, therefore a main test had to be performed.

In the main test, mixtures of test item/cellulose were prepared containing 10 to 90 % weight of test item in 10 % increments. Only the mixture with 10% substance burnt the whole required distance of 200mm, but at a significantly slower rate than the reference mixture that had been tested earlier. The test was repeated 6 times in total for the 10% mixture and the results were statistically significant (within 10% range from the arithmetic mean value).

Therefore Slags, ferronickel-manufg./Electric Furnace Slag / Converter Slag is not considered to be an oxidizing substance.

Justification for classification or non-classification

The highest burning rate was observed for a test item/cellulose-mixtures with 10 % test item. The burning rate of this mixture was significantely lower then the burning rate of the referance mixture. Therefore Slags, ferronickel-manufg./Electric Furnace Slag / Converter Slag is not considered to be an oxidizing substance and do not have to be classified and have no obligatory labelling requirement
