Interpretation of results:

GHS criteria not met

Conclusions:

According to EU A.17 test method, the substance is not considered as an oxidizing substance. Therefore, the substance has not met GHS criteria.

Executive summary:

The oxidizing property of the substance was determined according to EC REGULATION No 440/2008 Annex A.17 Oxidizing Properties (Solids). The result of preliminary test showed that the combustibility did not sustain, so the full train test is necessary. In the train test, the result showed that the piles of sample cellulose-mixtures containing 10 to 90 % weight ignited in 2 min, but the flame self-extinguished during the spreading. The maximum burning rate of mixture of sample with cellulose is less than the maximum burning rate of the reference mixture 1.21 mm/s.Therefore, the substance is not considered as an oxidizing substance.

Description of key information

The substance is not considered as an oxidizing substance (EC A.17).

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Additional information

The result of preliminary test showed that the combustibility did not sustain, so the full train test is necessary. In the Train Test, the result showed that the piles of sample cellulose-mixtures containing 10 to 90 % weight ignited in 2 min, but the flame self-extinguished during the spreading. The maximum burning rate of mixture (sample with cellulose) is less than maximum burning rate of reference mixture 1.21 mm/s. Therefore, the substance is not considered as an oxidizing substance.

 

Justification for classification or non-classification

The result of preliminary test showed that the combustibility of the substance was not sustained.

In accordance with the criteria for classification as defined in Annex I, Regulation (EC) No 1272/2008, the material does not require classification with respect to oxidising properties.
