| Abstract: | Two new methods—moisture at 130–133°C and fatty substances extracted by petroleum ether—were collaboratively tested by 14 laboratories (EBC and IOB Analysis Committee members and other laboratories). For moisture the following values were obtained in the range 12 to 15% m/m, repeatability=0.13% m/m and reproducibility=0.60% m/m. For fatty substances in the range 0.3 to 0.9% m/m the following values were obtained: repeatability=(0.06 m+0.02)% m/m and reproducibility=(0.14 m+0.09)% m/m. Both methods were accepted and will replace methods 6.1 and 6.4 respectively in Analytica EBC. The method for Fatty Substances will replace IoB methods 4.1.3 and 4.2.3. These modifications will become operative on 1 September, 1996. |
