- Key result
- Remarks on result:
- no self-ignition observed up to the melting point

- The substance has no relative self-ignition temperature up to the melting point.
- Executive summary:
A study was conducted according to Regulation (EC) No 440/2008 Part A A.16 to determine the relative self-ignition temperature of the test substance. A homogeneous sample was transferred into a cube. The cube was tapped gently and additional sample was filled into the cube. The sample was placed into the centre of the oven and two thermocouples were fixed. The oven was started with a temperature increasing rate of 0.47°C/min. The test ended at a temperature of 60°C and was performed one time. The recorded temperatures are used to construct a temperature time curve. Up to the upper limit of the melting point no significant deviation of the two temperature curves was observed. The test substance was totally melted and was flown through the mesh by the end of the test. Thus, the substance has no relative self-ignition temperature up to the melting point.
