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

Three replicate tests were performed. The test item did not self-ignite up to the melting point (range of 204 to 205 °C according to literature).

Conclusions:
No self-ignition temperature could be stated up to the melting point.
Executive summary:

A study was performed according to Regulation (EC) No. 440/2008, method A.16 in order to determine the relative self-ignition temperature of the solid test item by using an auto-ignition temperature tester ZPA 3. The oven was heated from ambient temperature to 210 °C with a rate of about 0.6 °C/min (temperature of test item increased by about 0.5 °C/min). No self-ignition of the test item could be stated up to the melting point of the test item (melting range 204 to 205 °C according to literature). Thus, no self-ignition temperature was determined.

Description of key information

No self-ignition temperature could be stated up to the melting point.

Additional information

A study was performed according to Regulation (EC) No. 440/2008, method A.16 in order to determine the relative self-ignition temperature of the solid test item by using an auto-ignition temperature tester ZPA 3. The oven was heated from ambient temperature to 210 °C with a rate of about 0.6 °C/min (temperature of test item increased by about 0.5 °C/min). No self-ignition of the test item could be stated up to the melting point of the test item (melting range 204 to 205 °C according to literature). Thus, no self-ignition temperature was determined (reference 4.12-1).
