Remarks:

Hess. Ministerium für Umwelt, Klimaschutz, Landwirtschaft und Verbraucherschutz; Wiesbaden, Germany

Test procedure:

other: 8 cm3 sample volume heated at 1.2 K/min in air.

Max. temp. reached:

420

Result:

negative outcome (no effect observed)

Remarks:

Not self-heating: onset temperature is > 220 ºC in the Grewer Oven test.

Remarks on result:

other: Exothermic effect started at 370 ºC leading to a maximum temperature of 420 ºC.

Results

Self-ignition in the Grewer Oven

In the investigation of self-heating in the Grewer Oven for the pure test item a first endothermic effect was detected in the temperature range of 100 - 160 °C. A second endothermic effect was detected in the temperature range of 250 - 280 °C and a third in the temperature range of 320 - 370 °C. An exothermic effect was detected starting at 370 °C, which led to a maximum temperature of 420 °C. After the measurement a brown residue remained in the basket.
