Referenceopen allclose all
Preliminary Test: The test substance melted on contact with the burner flame but did not propagate combustion. The burning time could not be measured.
The material exhibited combustion properties in the test. The combustion propagated fully by melting and burning with flame.
Combustion Class 5
The test was repeated at 100 °C, airflow 0.5 m/s; burning time for 100 mm = 50 s.
The material exhibited combustion properties in the test. The combustion propagated fully by melting and burning with flame.
Combustion Class 5
No gas was evolved in Steps 1 -3. No gas evolved on contact with water over 7 hours in Step 4.
No signs of ignition were observed during dropping or following 5 minutes.
Description of key information
Flammability (solids): not readily combustible, EU Method A.10, Jackson 1999
Flammability (solids): not readily combustible, UN Method N.1, Bailey 2010
Flammability (contact with water): no gas evolution; no ignition, EU Method A.12, Jackson 1999
Flammability (contact with air): no spontaneous ignition at ambient temperature, EU Method A.13, Jackson 1999
Key value for chemical safety assessment
- Flammability:
- not classified
Additional information
A single study conducted according to Regulation (EC) No. 440/2008 guidelines and under GLP is available for each aspect of flammability. The studies are considered to be relevant, reliable (Klimisch 1) and adequate for the purposes of risk assessment, classification and labelling.
A further non-GLP study, conducted according to the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, 5th Ed., Test N1, also indicated that the substance was not readily combustible. However, under the conditions of the test combustion propagated fully, but longer than the cut-off criteria.
Justification for classification or non-classification
The available experimental test data are considered reliable and suitable for classification purposes under Regulation (EC) No. 1272/2008, Annex I, section 2.7, 2.10, 2.12. The substance is not considered to be flammable according to the criteria given in test methods N1, N2, and N5 of the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part III. As a result the substance is not considered to be classified for flammability under Regulation (EC) No. 1272/2008.
