Applicant's summary and conclusion

Conclusions:
The pure test item Ampholak 7CX/C indicated self-ignition at atmospheric pressure starting at a temperature of 110 °C.

Due to the fact that the onset temperature in the Grewer oven is below the threshold of 220 °C (110 °C + safety margin of 80 K), the test item cannot be
excluded from classification as self-heating substance. For a detailed classification further tests according to UN Test N.4 are necessary.
On the basis of the results of the tests on the self-ignition in the Grewer oven the test item is classified as follows:

UN Transport Regulation: The test item cannot be excluded from classification as self-heating substance in class 4, division 4.2 according to the UN
Transport Regulation.

GHS / CLP Regulation EC 1272/2008 Annex 1: 2.11: The test item cannot be excluded from classification as self-heating substance according to GHS/CLP
Regulation EC 1272/2008 Annex 1: 2.11, respectively 
Executive summary:

The pure test item Ampholak 7CX/C indicated self-ignition at atmospheric pressure starting at a temperature of 110 °C. Due to the fact that the onset temperature in the Grewer oven is below the threshold of 220 °C (110 °C +safety margin of 80 K), the test item cannot be excluded from classification as self-heating substance. For a detailed classification further tests according to UN Test N.4 are necessary.

On the basis of the results of the tests on theself-ignition in theGrewer oventhe test item is classified as follows:

UN Transport Regulation:The test item cannot be excluded from classification as self-heating substance in class 4, division 4.2 according to the UN Transport Regulation.

GHS / CLP Regulation EC 1272/2008 Annex 1: 2.11:The test item cannot be excluded from classification as self-heating substance according to GHS/CLP Regulation EC 1272/2008 Annex 1: 2.11, respectively
