Key result

Sample tested:

test mixture as specified

Remarks:

test substance with cellulose in various weight ratios (from 10% to 90%)

Parameter:

burning rate

Result:

0.5 mm/s

Remarks on result:

other: the train did not burn completely

Results of the preliminary:

After applying the flame of burner, the sample ignites but the flame is not spread to the rest of the train. Result is negative.

Results of the train test: Results of determination of oxidizing properties for the reference mixture:

Barium nitrate  (V) [%]	10	20	30	40	50	60	70	80	90
Cellulose [%]	90	80	70	60	50	40	30	20	10
Burning time of the pile [s]	104	95	96	97	111	96	132	240	NI
Burning rate of the pile [mm/s]	1.92	2.11	2.08	2.06	1.80	2.08	1.52	0.83	-
Maximal burning rate of the reference mixture pile [mm/s]	2.11

NI: The train does not ignite.

Part I: measure of burning time and burning rate of piles (200 mm) of mixture test substance with cellulose in various weight ratios (from 10% to 90%) is shown below. During the determination, the substance burnt completely.

Results of determination of oxidizing properties for test item:

Test substance  (content in mixture) [%]	10	20	30	40	50	60	70	80	90
Cellulose (content in mixture) [%]	90	80	70	60	50	40	30	20	10
Burning time of the pile [s]	(50mm/62s)*	(20mm/39s)*	(45mm/96s)*	(20mm/43s)*	NI	NI	NI	NI	NI
Burning rate of the pile [mm/s]	(0.5)*	(0.5)*	(0.5)*	(0.5)*	-	-	-	-	-
Maximal burning rate of the reference mixture pile [mm/s]	2.11

* the train does not burn completely.

NI: the train does not ignite.

Burning rate of the train of mixture test substance with cellulose in weight ratio 90% to 10 % is much smaller (the train does not ignite) than maximal burning rate of the reference mixture train.

Interpretation of results:

GHS criteria not met

Remarks:

In the preliminary test there was not a vigorous reaction

Conclusions:

Test item has not oxidizing properties in accordance with EU Method A.17 criteria.

Executive summary:

The determination of the oxidising properties of the test substance was performed according to EU method A.17 and GLP study. Burning rate of the train of mixture test substance with cellulose in weight ratio 90% to 10 % is much smaller (the train does not ignite) than maximal burning rate of the reference mixture train. The test item has no oxidizing properties in accordance with EU Method A.17 criteria.
