- Conclusions:
- D-8 was tested for oxidising properties in a test according to EU Gudeline A.17. D-8 was determined to be an oxidiser since the maximum burning rate of the test substance mixtures with cellulose was greater than that of the reference substance mixtures with cellulose. However, as the test substance is a solid with a comparatively low melting point, this result was considered a false positive.
In a repeat experiment, D-8 did not support combustion when mixed with an inert material, celite. C Consequently, the result obtained in the standard oxidising properties test A.17 could be considered valid. - Executive summary:
D-8 was tested for oxidising properties in a test according to EU Gudeline A.17.The test substance and cellulose were mixed in various weight proportions (from 10/90 to 90/10).Each mixture was formed into a train about 250 mm long and the hot flame of a propane/butane gas burner was applied to one end of the train.The burning rate was measured over 200 mm after the reaction zone has propagated an initial distance of 30 mm.This test was performed for each mixture, repeated six times for each of the three mixtures revealing the fastest burning rate.
D-8 was determined to be an oxidiser, since the maximum burning rate of the test substance mixtures with cellulose was greater than that of the reference substance mixtures with cellulose. However, as the test substance is a solid with a comparatively low melting point however, this result was considered a false positive. Further testing was therefore proposed and undertaken in order to distinguish between the two effects.
Part of the study was repeated, with cellulose replaced by an inert substance, celite. Celite would not be affected by any oxidising properties of the test substance. D-8 did not support combustion when mixed with celite. Consequently, the result obtained in the standard oxidising properties test A.17 could be considered valid.

Justification for classification or non-classification
Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
Based on the chemical structure and taking into account the provisions laid down in Regulation (EC) No 1272/2008, as amended for the twelfth time in Regulation (EU) No 2019/521, the substance is not considered to be classified for oxidising properties.
