Sample tested:

reference mixture (not specified)

Parameter:

maximum burning rate

Result:

1.01 mm/s

Remarks on result:

other: mixture with 60 wt.% oxidizer (barium nitrate)

The maximum burning rate of the mixtures of the test item and cellulose (0.68 mm/s) was slower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.01 mm/s). Due to these results, the test item has no oxidizing properties.

Individual Results

Preliminary test

Three tests mixtures with the test item and cellulose 2:1 burned did not burned down completely. The

flame extinguished after a period of 118, 38 and 123 s. The flame burned only on the surface.

Three tests mixtures with barium nitrate/cellulose 2:1 burned down completely in 82, 85 and 81 s.

Therefore the full test was necessary, because the test item burned down not completely.

Five tests were performed for the reference mixture (Barium nitrate and Cellulose) with 40, 50, 55, 60

and 70 wt.% oxidizer (barium nitrate). The results are shown in the following table.

Barium nitrate [wt.%]	Burning time over 200 mm [s]	Burning rate [mm/s]
40	302	0.66
50	244	0.82
55	231	0.87
60	199	1.01
70	337	0.59

 

Mixtures of the test item with cellulose were prepared in 10 %-increments between 10 and 90 wt.%

test item and tested. Additional tests with 5 and 15 wt.% test item were performed.

The following table shows the results.

Test item [%]	Burning time over 200 mm [s]	Burning rate [mm/s]
5	335	0.60
10	329	0.61
15	353	0.57
20	369	0.54
30	461	0.43
40	The flame extinguished after a period of 331 s and a distance of 100mm.	0.30
50	The flame extinguished after a period of 11 20 sand a distance of 35 mm.	0.29
60	The flame extinguished after a period of 181 s and a distance of 45 mm.	0.25
70	885	0.23
80	The test item could not be ignited with a flame, the test item melted.	___
90	The test item could not be ignited with a flame, the test item melted.	___

 

Six tests were performed for the three mixtures with the highest burning rates (5, 10 and 15 wt.% of

test item)

15	353	0.57	357	0.56	368	0.54	361	0.55	351	0.57	359	0.56

 

The highest burning rate 0.68 mm/s was found for the mixture with 10 % test item.

Interpretation of results:

other: no oxidising properties

Description of key information

non oxidising

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Additional information

EU Method A.17

The maximum burning rate of the mixtures of the test item and cellulose (0.68 mm/s) was slower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.01 mm/s). Due to these results, the test item has no oxidising properties.

Justification for classification or non-classification

No classification, the substance is non oxidising.

Justification: The maximum burning rate of the mixtures of the test item and cellulose (0.68 mm/s) was slower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (1.01 mm/s). Due to these results, the test item has no oxidising properties according to regulation 67/548/EEC Annex V.

The substance is incapable of reacting exothermically with combustible materials on the basis of the chemical structure (regulation 1272/2008; CLP).
