Any other information on results incl. tables

1) In the screening test according to Grewer self.ignition was observed at 280°C. Weak heating was observed from 300°C as a result of decomposition. Above 400°C, self-heating was strong leading to open fire.

2) Maximum temperature: 232 °C

Time to maximum temperature: 57 min.

Self-heating: 32 K over the entire duration

Applicant's summary and conclusion

Conclusions:
Classification of the test item as auto-flammable substance according to section 4.2. of transport regulations is not required.
Executive summary:

In a screening test according to Grewer and a hot storage test for self heating, the test substance did not show auto-flammable properties.
