Procedure:

Sample preparation;

Volatile compounds have been removed from the test substance for               3 h

At                                                                                                                30 °C

Weight of sample before drying                                                                     9.92 g

Weight of sample after drying                                                                        9.90 g

Relative change                                                                                             0.2 %
