RESULTS:

Table 1. Initial test - Burning rate versus sample composition

Mixture (%)		** Burning rate	Reaction
Test substance	Cellulose	(mm/s)
20 40	80 60	1.5 1.0	Steady burning with flame throughout the whole mass
60	40	0.5	Steady burning with flame, only the ledge of the pile.
80	20	-	Burning does not propagate to 1st ref. mark.

** only one test

 

Table 2. Main test - Burning rate versus sample composition

Mixture (%)		*Max burning rate	Reaction
Test substance	Cellulose	(mm/s)
5	95	2.0	Steady burning with flame throughout the whole mass.
10	90	1.9
20	80	1.7

* In a run of six tests

* Max. burning rate: mixture with 5 % of product

*[Max burning rate test mixture] / [*max burning rate reference mixture] = [2.0 mm/s] / [5.4 mm/s] = 0.4

Interpretation of results:

GHS criteria not met

Conclusions:

The maximum burning rate of the test substance (2.0 mm/s at 5 % test substance and 95% cellulose) was lower than the maximum burning rate of the reference substance, barium nitrate/cellulose, (5.4 mm/s at 60:40). The product is therefore not considered an oxidising substance.

Executive summary:

The oxidising potential of the test substance was determined according to EC test A.17 following GLP principles. The maximum burning rate of the test substance (2.0 mm/s at 5 % test substance and 95 % cellulose) was lower than the maximum burning rate of the reference substance, barium nitrate/cellulose, (5.4 mm/s at 60:40). The product is therefore not considered an oxidising substance.

Description of key information

Oxidising properties: The maximum burning rate of the test substance was lower than the maximum burning rate of the reference substance. The product is therefore not considered an oxidising substance, EC test A.17, Schürch 1992

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Justification for classification or non-classification

Based on the available information, classification on oxidising properties is not warranted in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. (EC) 1272/2008.
