Key result
Test procedure:
other: Grewer oven
Remarks:
pure test item
Max. temp. reached:
485
Result:
other: An exothermic process was observed starting at a temperature of approx. 225 °C that led to a maximum temperature of approx. 485 °C.

In the investigation of self-ignition in the Grewer Oven for the pure test item an endothermic effect was detected in the temperature range of 50 – 170 °C. An exothermic process was observed starting at a temperature of approx. 225 °C that led to a maximum temperature of approx. 485 °C (corresponding oven temperature 320 °C). After the measurement a grey residue remained in the wire basket.

Interpretation of results:
not classified based on GHS criteria
Conclusions:
The pure test item 4-Nitrophenyl phosphate disodium salt (CAS no. 4264-83-9) indicated a self-heating at atmospheric pressure starting at a temperature of approx. 225 °C that led to a maximum temperature of approx. 485 °C (corresponding oven temperature 320 °C).
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 is not classified 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 is not classified as self-heating substance according to GHS/CLP Regulation EC 1272/2008 Annex 1: 2.11, respectively.
Executive summary:

The pure test item 4-Nitrophenyl phosphate disodium salt (CAS no. 4264-83-9) indicated a self-heating at atmospheric pressure starting at a temperature of approx. 225 °C that led to a maximum temperature of approx. 485 °C (corresponding oven temperature 320 °C).

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 is not classified 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 is not classified as self-heating substance according to GHS/CLP Regulation EC 1272/2008 Annex 1: 2.11, respectively.
