ANNEX
METHOD OF DETERMINING THE ASH CONTENT OF FLOUR
APPARATUS
1 . LABORATORY SCALES SENSITIVE TO 0.01 MG .
BOX OF CORRESPONDING WEIGHTS .
2 . ELECTRIC MUFFLE KILN , WITH ADEQUATE DRAUGHT AND A TEMPERATURE GAUGE AND REGULATOR .
3 . ROUND , FLAT-BOTTOMED INCINERATION DISHES ( ABOUT 5 CM IN DIAMETER , MAXIMUM HEIGHT 2 CM ) , PREFERABLY OF GOLD AND PLATINUM ALLOY OR OF QUARTZ OR PORCELAIN .
4 . DESICCATOR ( WITH AN INTERNAL DIAMETER OF ABOUT 18 CM ) FITTED WITH A NECK AND A PERFORATED PLATE , IN PORCELAIN OR ALUMINIUM .
DEHYDRATION AGENT : CALCIUM CHLORIDE , PHOSPHORUS PENTOXIDE OR SILICA GEL COLOURED BLUE .
METHOD
1 . THE WEIGHT OF THE TEST SAMPLE SHOULD BE BETWEEN 5 AND 6 G . WHEN IT IS FLOUR OF WHICH THE ASH CONTENT REFERRED TO DRY MATTER IS LIKELY TO BE OVER 1 % , THE WEIGHT OF THE TEST SAMPLE SHOULD BE BETWEEN 2 AND 3 G . THE WEIGHT OF THE TEST SAMPLE MAY BE ROUNDED TO THE NEAREST 10 MG ; ALL OTHER QUANTITIES ARE WEIGHED TO THE NEAREST 0.1 MG .
2 . IMMEDIATELY BEFORE USE THE DISHES MUST BE HEATED IN THE MUFFLE KILN AT INCINERATION TEMPERATURE TO CONSTANT WEIGHT ; A PERIOD OF FIFTEEN MINUTES IS USUALLY SUFFICIENT .
THE DISHES ARE THEN COOLED IN THE DESICCATOR TO LABORATORY TEMPERATURE UNDER THE CONDITIONS INDICATED IN PARAGRAPH 7 .
3 . PLACE THE TEST SAMPLE IN THE DISH AND SPREAD IT OUT IN AN EVEN LAYER , WITHOUT HEAPING . IMMEDIATELY BEFORE INCINERATION DAMP THE TEST SAMPLE WITH 1 TO 2 ML OF ETHYL ALCOHOL .
4 . PLACE THE DISHES
