Description of key information
Using a linear increase in temperature of 0.5 K/min, the test substance shows one exothermic reactions. The exothermic reaction started at about 252 °C. A maximum temperature of about 278 °C was measured in the sample cube. At the end of the run, the test substance showed a loss of mass of about 74 % and coloured black. In conclusion, the test substance is not auto-flammable, according to the criteria as described in the guidelines.
Key value for chemical safety assessment
Additional information
The relative self-ignition temperature of the test substance was determined according to EU method A.16. Using a linear increase in temperature of 0.5 K/min, the test substance shows one exothermic reactions. The exothermic reaction started at about 252 °C. A maximum temperature of about 278 °C was measured in the sample cube. At the end of the run, the test substance showed a loss of mass of about 74 % and coloured black. As mentioned in IUCLID section 4.2 at temperatures in the vicinity of the melting temperature (225 °C) the test substance started to decompose. In conclusion, Urea 6 is not auto-flammable, according to the criteria as described in the guidelines.
