- Executive summary:
The self-ignition behavior of the product was determined in the Grewer Oven according to VDI 2263, sheet 1 and with respect to the classification procedures of both the UN Transport Regulation (Class 4, Division 4.2). The test equipment consisted of an oven with six wire baskets with a volume of 8 cm³, a temperature controller and a temperature recorder. The wire baskets including the test item and the reference material (graphite) were heated at a rate of 1.2 K/min at atmospheric pressure in an air stream of 100 to 120 l per hour. The surrounding temperature at which the temperature of the test item begins to exceed the temperature of the reference material was considered as onset temperature of the self-ignition.
The pure test item showed a negligible self-heating at atmospheric pressure starting at a temperature of approx. 210 and 230 °C, which leaded to a maximum temperature of 230 and 245 °C, respectively.
Conclusion
The test item has not to be classified as self-heating substance in class 4, division 4.2 according to the UN Transport Regulation.
Reference
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 – 160 °C, which may be caused by the drying of the test item (3.2 % water). Starting at a temperature of approx. 210 °C the test item showed an exothermic effect, which leaded to a maximum temperature of 230 °C (reference temperature 225 °C). A second exothermic effect was observed at a temperature of 230 °C, which leaded to a maximum temperature of 245 °C (reference temperature 240 °C). No further exothermic effects were observed until the maximum test temperature of 410 °C. After the measurement a black residue remained in the basket.
For the test item in mixture with Kieselguhr no exothermic effects were detected.
