as an oxidising substance. - Executive summary:
his study followed the procedures indicated by the following internationally accepted guideline and recommendation: -Council Regulation (EC) No. 440/2008, Annex, Part A, A.17.: “Oxidising Properties (solids)”, Official Journal of the European Union, L 142, Volume 51, 31 May 2008.
The cone-shaped pile formed during the Preliminary Test could not be ignited therefore the
Main Test was performed.
The test item did not ignite in the Main Test at any of the mixing ratios. 2,4,8,10-Tetraoxa-
3,9-dithiaspiro[5.5]undecane, 3,3,9,9-tetraoxide is not considered as an oxidising substance.Table 2 Main Test

Reference
Preliminary Test
The dried test item was thoroughly mixed with the dried cellulose in the
proportions 2 of test
item to 1 of cellulose by weight and the mixture was formed into a small
cone-shaped pile of
dimensions 3.5 cm (diameter of base) x 2.5 cm (height) by filling,
without tamping a coneshaped former.
The pile was placed on a cool, non-combustible, non-porous and low
heat-conducting base
plate. The ignition source was put in contact with the cone. The vigour
and duration of the
resultant reaction was observed and recorded.
Main Test
Oxidiser cellulose-mixtures containing 10 to 90 % weight of oxidiser in
10 % increments
were prepared.
The pile was formed by means of a mould. The mould was loosely filled
with a slight excess
of mixture. After dropping the mould once from a height of 2 cm onto a
solid surface, the
remaining excess substance was scraped off with an obliquely positioned
sheet. The lateral
limitations were removed and the remaining powder was smoothed. A
non-combustible,
non-porous and low heat-conducting base plate was then being placed on
top of the mould,
the apparatus inverted and the mould removed.
One end of the pile was ignited by touching with a flame.
The time of reaction was measured over a distance of 200 mm after the
reaction zone had
propagated an initial distance of 30 mm.
The test was performed with the reference item and once with each one of
the range of
mixtures of the test item with cellulose.
Description of key information
The cone-shaped pile formed during the Preliminary Test could not
be ignited therefore the Main Test was performed.
The test item did not ignite in the Main Test at any of the mixing
ratios. 2,4,8,10-Tetraoxa-3,9-dithiaspiro[5.5]undecane,
3,3,9,9-tetraoxide is not considered as an oxidising substance.
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
