Key result
Test procedure:
100 mm sample cube at 140°C
Max. temp. reached:
Induction time (h):
negative outcome (no effect observed)

For the test in the 10 cm cube at an oven temperature of 140 °C ±2 °C an amount of 733.3 g of the test item was filled in the sample container. The test item temperature reached the oven temperature (141 °C) after approximately 9 hours. After at least 24 hours the test was stopped without detecting exothermal effects. The maximum sample temperature was 139 °C.

After the measurement the mesh wire basket contained approximately 2 wt.% less test item than at the start. The remaining test item showed no visual changes.

Due to the negative result at 140 °C (10 cm cube) the test item had not to be classified as "self-heating substance" in the sense of UN Manual of Tests and Criteria, Method N.4., and had not to be classified as "self-heating substance" according to chapter 2.1 Il of the GHS (CLP) regulations.
