Performance of the test
Preliminary test
The substance was thoroughly mixed with the dried cellulose in the proportions 2 of test substance to 1 of cellulose by weight. 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 cone-shaped former. The pile was placed on a cool, non - combustible, non-porous
and low heat-conducting base plate. The test was carried out in a fume cupboard.
The ignition source was put in contact with the cone. The vigour and duration of
the resultant reaction burning of mixture of test item and cellulose were observed
and recorded.
Comparison of obtained data for the cones made of mixtures: of test item with cellulose and of barium nitrate(V) with cellulose in weight ratio 2:1. Results are shown in Table 3.

The result of preliminary test is negative and therefore, the full test must be conducted.
Train test
Prepared oxidizer cellulose-mixtures containing 10% to 90% weight of oxidizer in 10% increments. The pile was formed by means of a mould. The mould was made of metal,
has a length of 250 mm and a triangular cross-section with an inner height of 10 mm
and an inner width of 20 mm. On both sides of the mould, in the longitudinal direction, two metal plates are mounted as lateral limitations which project 2 mm beyond the upper edge of the triangular cross-section. This arrangement 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, using a roller. A noncombustible, non-porous and low heat-conducting base plate is then placed on the top of the mould, the apparatus inverted and the mould removed.
The pile was arranged across the draught in a fume cupboard. The air-speed was the same during the test. Due to hygroscopicity of cellulose and of some substances to be tested, the test was carried out as quickly as possible. The pile was ignited on the one end by touching with the flame. The time of reaction was measured over a distance of 200 mm after the reaction zone has propagated an initial distance of 30 mm. The test was performed with the reference substance and at least once with each one of the range of mixtures of the test substance with cellulose. The maximum burning rate obtained
was compared with the maximum burning speed of the reference mixture. Results of determination of oxidizing properties for the reference mixture (barium nitrate(V)
and cellulose) were shown below in Table 4.

The mixtures of test item and cellulose burnt incompletely. Hence In this case there is not the highest value of burning rate. Hence the repetition of additional five tests is not appropriate. The burning rate of the train is not calculated and test item is considered as substance which does not meet criteria for oxidizing substances.
Conclusion
Aspartic Acid Sodium Salt Monohydrate – min. 98% - ADCF (L-Aspartic acid monosodium salt monohydrate) does not have the oxidizing properties in accordance with method EC A.17 criteria.
