Description of key information
In compliance with Regulation (EC) No. 1907/2006, Council Regulation (EC) No. 440/2008, EC A.17. Method (2008) for 3-Bromo-1-(3-Chloro-2-Pyridyl)-5-Methyl-1H-Pyrazole the following parameters were measured:
The maximum burning rate obtained with the test item was 2.50 mm/s for the test item / cellulose mixture (20/80% w/w).
The maximum burning rate obtained with the reference item was 2.94 mm/s for the reference item / cellulose mixture (10/90% w/w).
The maximum burning rate of test item / cellulose mixture was slower than the maximum burning rate with reference item / cellulose mixture.
The test item was not considered to have oxidizing properties under the experimental conditions used.
Justification
No oxidising properties were found in a test according to EC A.17 (2008).
Key value for chemical safety assessment
- Oxidising properties:
- non oxidising
Additional information
Justification for classification or non-classification
No oxidising properties were found in a test according to EC A.17. (2008). This is in accordance with the chemical structrure of the substance. According to EU regulation 1272/2008 no classsification is necessary.
