The one liter sample held at 140 °C rose to only 148 °C (delta T = 8 °C) and held this temperature for the rest of the test, just beginning to drop near the end. This was an unusual result, normally the temperature peaks in the first few hours then drops off.
The oven was supposed to work correctly.
As a temperature rise of 60 °C is required for a "positive" test, the small temperature rise of 8 °C in this test means that the substance is not self-heating at this sample size and temperature.
Self-heating of the test item was observed at 280 °C (max. temp. ca. 350 °C). Another self-heating effect was observed at ca 400 °C (max. temp. ca. 425 °C). The wire mesh basket was empty after the test, which indicates liquidation and self-heating of the residues at 400 °C.
The mixture of the test item with kieselguhr (1:1) showed self-heating at 310 °C (max. temp. ca.375 °C) and at 350 °C (max. temp. ca. 800 °C)
These observations are explained by exothermal decomposition of the test substance.
