a) not used for regression

Measurement error: pressure: 0.1%, at least 0.05 hPa;Temperature: 0.04 K.

When heating from approx. 235 ° C to approx. 250 ° C, slight smoke development was briefly observed.
From a temperature of about 250 ° C, a continuously falling temperature indicates a thermal change of the test substance
