Reference mixture

Barium nitrate: Powdered cellulose = 3 : 2

Burning time: 165 s

Burning rate: 1.21 mm/s

Interpretation of results:
GHS criteria not met
Conclusions:
According to EU A.17 test method, Evercion SR61 is not considered as an oxidizing substance. Therefore, Evercion SR61 was not met GHS criteria.

Executive summary:

The oxidizing property of Evercion SR61 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 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 maximum burning rate of reference mixture 1.21 mm/s.Therefore, Evercion SR61 is not considered as an oxidizing substance.

Description of key information

Evercion SR61 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 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,Evercion SR61 is not considered as an oxidizing substance.
