Remarks on result:
preliminary test

In the investigation of self-ignition in the Grewer Oven for the pure test item shows no self-ignition up to the maximum test temperature of 410 °C. Only an endothermic effect (melting) was observed in the temperature range of approx. 30 – 120 °C. After the measurement the basket was nearly empty, since the test substance melted and ran out of the basket.

Results of the screening test for self-ignition in the Grewer Oven

 Experiment  Start of effects / °C  Maximum temperature / °C
 Pure test item  ---  410

The pure test item lead di(acetate) trihydrate indicated no self-ignition up to the maximum test temperature of 410 °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 has not to be 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 has not to be classified as self-heating substance according to GHS/CLP Regulation EC 1272/2008 Annex 1, Section 2.11.

Conclusions:
The pure test item lead di(acetate) trihydrate indicated no self-ignition up to the maximum test temperature of 410 °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 does not require 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 does not require classification as self-heating substance according to GHS/CLP Regulation EC 1272/2008 Annex 1, Section 2.11.
