EC number: 214-787-5 | CAS number: 1194-65-6
Ratio 10 (test material)/90 (cellulose) to 50/50: the mixtures burned with an orange flame (height 2-4 cm; width 5-10 cm) emitting smoke
Ratio 60/40: after 20 seconds the flame was extinguished; the burning distance was less than 2 cm
Ratio 70/30: after 10 seconds the flame was extinguished; the burning distance was less than 1 cm
Ratio 80/20: after 5 seconds the flame was extinguished; the burning distance was less than 1 cm
Ratio 90/10: the mixture did not burn
The 100 % cellulose pile could not be ignited. The barium nitrate/cellulose 70/30 mixture burned and emitted grey smoke. The pile burned for approximately 35 seconds. The test material/cellulose mixtures could not be ignited.

In a GLP compliant oxidising properties study conducted in accordance with the standardised guideline EU Method A.17, the oxidising properties of the test material were determined. Under the conditions of the study, the test material was determined to be non-oxidising.
The test material was determined to be non-oxidising according to a study performed in line with EU Method A.17.
The key study (Krips, 1995b) was performed in line with GLP and standardised guidelines with a sufficient level of detail to assess the quality of the study. The study was performed to a good standard and was assigned a reliability score of 1 using the principle for assessing data quality as set out in Klimisch (1997).
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.
