In the screening test according to Grewer with the pure test substance an exothermal effect starting at 320°C was observed leading to a maximum temperature of 370°C.
In the screening test with the kieselgur mixture (1:1) an exothermal effect starting at 320°C was observed. Self-heating led to a temperature of 410°C.
In the screening test according to Grewer with the pure test substance an exothermal effect starting at 310°C was observed without further temperature increase (foaming of the test substance)
In the screening test with the kieselgur mixture (1:1) an exothermal effect starting at 300°C was observed. Self-heating led to a temperature of 580 °C.
