- Executive summary:
The determination of the oxidising properties of the substance has been evaluated according to the EU Method A.17. The substance was dried in an exsiccator and sieved through a 125 µm sieve. Based on preliminar test, different mixutres of test item and cellulose and the reference substance and cellulose were prepared. The pile was ignited at one end with the flame of the Bunsen burner. When the flame had propagated over a distance of 30 mm, reaction time along the next 200 mm was measured using a stop watch. All reference substance mixtures showed clear signs of oxidising properties (cracks, spar-kling) and burned with a green-orange flame. All test substances mixtures showed no signs of oxidising properties. The mixtures 10/90, 20/80, 30/70 and 40/60 carbonized and smoke was observed. The mixtures 50/50, 60/40, 70/30, 80/20 and 90/10 carbonized only at the same place. No sparkling and cracks were observed. As the burning rate was lower than the highest burning rate of the reference item mixtures, the determination of burning rate was repeated five times for each of the three mixtures test item/cellulose (10%; 20%; 30%) with the highest burning rates. The highest burning rate of the three mixtures test substance/cellulose with the highest burning rate was determined to be 2.15 ± 0.06 mm/s. The maximum burning rate of the reference substance was determined to be 3.21 mm/s. Therefore, the test substance is considered to have no oxidising properties.

The highest burning rate of the three mixtures test substance/cellulose with the highest burning rate was determined to be 2.15 ± 0.06 mm/s. The maximum burning rate of the reference substance was determined to be 3.21 mm/s. Therefore, the test substance is considered to have no oxidising properties.
None of the deviations surpasses 10%. Therefore, the study is considered as valid.
