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 IN THE MOUTH OF THE KILN , THE DOOR OF WHICH REMAINS OPEN . WHEN THE SUBSTANCE HAS CEASED TO FLAME , PUSH THE DISHES INTO THE KILN . WHEN THE KILN DOOR HAS BEEN CLOSED , AN ADEQUATE DRAUGHT MUST BE MAINTAINED , BUT NOT SO STRONG AS TO BLOW THE SUBSTANCE OUT OF THE DISHES .

5 . INCINERATION MUST RESULT IN THE TOTAL COMBUSTION OF THE FLOUR , INCLUDING ANY SOOTY PARTICLES AMONG THE ASHES . IF SHALL BE CONSIDERED AS COMPLETED WHEN THE RESIDUE IS ALMOST WHITE AFTER COOLING .

6 . THE INCINERATION TEMPERATURE MUST REACH 900 C .

7 . WHEN INCINERATION IS COMPLETED , REMOVE THE DISHES FROM THE KILN AND PLACE THEM ON A SHEET OF ETERNIT FOR ABOUT ONE MINUTE TO COOL , THEN PUT THEM IN THE DESICCATOR ( NOT MORE THAN FOUR DISHES AT A TIME ) . THE CLOSED DESICCATOR IS PLACED NEAR THE ANALYSIS SCALES . WEIGH THE DISHES WHEN THEY ARE COMPLETELY COLD ( ABOUT ONE HOUR ) .

RESULTS

1 . MARGIN OF ERROR : IF THE ASH CONTENT DOES NOT EXCEED 1 % , THE RESULTS OF A DOUBLE TEST SHOULD NOT DIFFER BY MORE THAN 0.02 UNITS OF ASH CONTENT ; IF THE ASH CONTENT EXCEEDS 1 % , THE DIFFERENCE SHOULD NOT EXCEED 2 % OF THE ASH CONTENT . IF THE DIFFERENCE EXCEEDS THESE LIMITS THE TEST MUST BE REPEATED .

2 . THE ASH CONTENT SHALL BE STATED PER 100 PARTS OF DRY MATTER AND ROUNDED TO 0.01 .
