TREATMENT OF TEST MATERIAL PRIOR TO TESTING
- Treatment of test material prior to testing:
Test substance was passed through a sieve 0.125 mm. Before preparing the mixture, substance was dried in a laboratory oven at (105 ± 2) ºC, until constant weight was obtained. A layer of test item was not more than 25 mm thick, time of drying: 12 hours.
The method of water content determination is based on drying test item in a laboratory oven. The water content of the tested test item was 0.38 % (w/w).

Interpretation of results:

GHS criteria not met

Conclusions:

Since de maximum burning rate of the mixtures tested (0.84 mm/s) is lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (V) (1.92 mm/s), the substance is regarded as not oxidising.

Executive summary:

The study of the determination of oxidising properties was performed according to the EU Method A.17, following the Principles of GLP. The tested substance gave negative results in the preliminary test and the maximum burning rate of the mixtures tested were lower than the observed in the reference mixture. Since de maximum burning rate of the mixtures tested (0.84 mm/s) is lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (V) (1.92 mm/s), the substance is regarded as not oxidising.

Description of key information

Key study: EU Method A.17. GLP study. Since de maximum burning rate of the mixtures tested (0.84 mm/s) is lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (V) (1.92 mm/s), the substance is regarded as not oxidising.

Key value for chemical safety assessment

Oxidising properties:

non oxidising

Additional information

Key study: The determination of oxidising properties was performed according to the EU Method A.17, following the Principles of GLP. The tested substance gave negative results in the preliminary test and the maximum burning rate of the mixtures tested were lower than the observed in the reference mixture. Since de maximum burning rate of the mixtures tested (0.84 mm/s) is lower than the maximum burning rate of the reference mixture of cellulose and barium nitrate (V) (1.92 mm/s), the substance is regarded as not oxidising.
