Key result

Test procedure:

other: Grewer oven

Remarks:

test item in mixture with Kieselguhr

Result:

negative outcome (no effect observed)

Remarks:

no endothermic or exothermic effects were observed

In the investigation of self-ignition in the Grewer Oven for the pure test item showed a multistage self-heating beginning at a temperature of 90 °C, which leaded to a maximum temperature of approx. 425 °C. A black residue remained in the wire basket after the test.

For the test item in mixture with Kieselguhr no endothermic or exothermic effects were observed.

Interpretation of results:

study cannot be used for classification

Conclusions:

The pure test item Disodium beta-glycerophosphat (CAS no. 819-83-0) indicated a self-heating at atmospheric pressure starting at a temperature of 90 °C. On the basis of the results of the tests on the self-ignition in the Grewer Oven according to the UN Recommendations on the TRANSPORT OF DANGEROUS GOODS: Manual of Tests and Criteria, Appendix 6 Division 4.2, a classification of the test item as self-heating substance cannot be excluded. Further tests have to be performed for the classification.

Executive summary:

The pure test item Disodium beta-glycerophosphat (CAS no. 819-83-0) indicated a self-heating at atmospheric pressure starting at a temperature of 90 °C. On the basis of the results of the tests on the self-ignition in the Grewer Oven according to the UN Recommendations on the TRANSPORT OF DANGEROUS GOODS: Manual of Tests and Criteria, Appendix 6 Division 4.2, a classification of the test item as self-heating substance cannot be excluded. Further tests have to be performed for the classification.
