Conclusions:

In summary the test item is not self-heating substance.
.

Executive summary:

In relation to self-heating properties the test item showed very high self-ignition temperatures of >280°C in screening tests for self-ignition according to Grewer. According to the Guidance on the Application of the CLP Criteria (Chapter 2.11), these data can be used for the assessment of self-heating properties. If the screening test identifies an onset temperature 80 K above the reference temperature of 140 °C for a volume of 1 L, i.e. and onset temperature of > 220°C, the substance does not has to be classified as possessing dangerous self-heating properties.
