Self-heating substances / mixtures 2

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

Any other information on results incl. tables

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.

Applicant's summary and conclusion

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.
