ANNEX I

A . MATTER OTHER THAN BASIC CEREALS OF UNIMPAIRED QUALITY

1 . BROKEN GRAINS :

ALL GRAINS OF WHICH ENDOSPERM IS PARTIALLY UNCOVERED SHALL BE CONSIDERED AS BROKEN GRAINS . GRAINS DAMAGED BY THRESHING AND GRAINS FROM WHICH THE GERM HAS BEEN REMOVED ALSO BELONG TO THIS GROUP .

THIS DEFINITION DOES NOT APPLY TO MAIZE .

2 . GRAIN IMPURITIES :

( A ) SHRIVELLED GRAINS :

GRAINS WHICH , AFTER ELIMINATION FROM THE SAMPLE OF ALL OTHER MATTER REFERRED TO IN THIS ANNEX , PASS THROUGH SIEVES WITH APERTURES OF THE FOLLOWING DIMENSIONS : COMMON WHEAT 2 MILLIMETRES , RYE 1.8 MILLIMETRES , DURUM WHEAT 1.9 MILLIMETRES , BARLEY 2.2 MILLIMETRES , SHALL BE CONSIDERED AS SHRIVELLED GRAINS .

IN ADDITION , GRAINS DAMAGED BY FROST AND UNRIPE GRAINS ( GREEN ) BELONG TO THIS GROUP .

( B ) OTHER CEREALS :

" OTHER CEREALS " MEANS ALL GRAINS WHICH DO NOT BELONG TO THE SPECIES OF GRAIN SAMPLED . IN THE CASE OF A SAMPLE OF DURUM WHEAT , ALL COMMON WHEAT GRAINS EXCEEDING 4 % SHALL COUNT AS " OTHER CEREALS " .

( C ) GRAINS DAMAGED BY PESTS :

GRAINS DAMAGED BY PESTS ARE THOSE WHICH HAVE BEEN NIBBLED . BUG-RIDDEN GRAINS ALSO BELONG TO THIS GROUP .

( D ) GRAINS IN WHICH THE GERM IS DISCOLOURED AND MOTTLED GRAINS :

GRAINS IN WHICH THE GERM IS DISCOLOURED ARE THOSE OF WHICH THE TEGUMENT IS COLOURED BROWN TO BROWNISH BLACK AND OF WHICH THE GERM IS NORMAL AND NOT SPROUTING . FOR COMMON WHEAT , GRAINS IN WHICH THE GERM IS DISCOLOURED SHALL BE DISREGARDED UP TO 8 % . FOR DURUM WHEAT , GRAINS WHICH SHOW A BROWN TO BROWNISH BLACK DISCOLORATION ELSEWHERE THAN ON THE GERM ITSELF SHALL BE CONSIDERED AS MOTTLED GRAINS .

3 . SPROUTED GRAINS :

SPROUTED GRAINS ARE THOSE IN WHICH THE RADICLE OR PLUMULE IS CLEARLY VISIBLE TO THE NAKED EYE .

HOWEVER , ACCOUNT MUST BE TAKEN OF THE GENERAL APPEARANCE OF THE SAMPLE WHEN ITS CONTENT , OF SPROUTED GRAINS IS ASSESSED . IN SOME KINDS OF CEREALS THE GERM IS PROTUBERANT , E.G . IN DURUM WHEAT , AND THE GERM TEGUMENT SPLITS WHEN THE BATCH OF CEREALS IS SHAKEN . THESE GRAINS RESEMBLE SPROUTED GRAINS BUT MUST NOT BE INCLUDED IN THAT GROUP . SPROUTED GRAINS ARE ONLY THOSE WHERE THE GERM HAS UNDERGONE CLEARLY VISIBLE CHANGES WHICH MAKE IT EASY TO DISTINGUISH THE SPROUTED GRAIN FROM THE NORMAL GRAIN .

4 . MISCELLANEOUS IMPURITIES ( SCHWARZBESATZ ) :

( A ) WEED SEEDS

( B ) DAMAGED GRAINS :

DAMAGED GRAINS ARE THOSE RENDERED UNFIT FOR HUMAN CONSUMPTION AND , AS REGARDS FEED GRAIN , FOR CONSUMPTION BY CATTLE , OWING TO PUTREFACTION , MILDEW , OR BACTERIAL OR OTHER CAUSES .

GRAINS WHICH HAVE DETERIORATED THROUGH SPONTANEOUS GENERATION OF HEAT ALSO BELONG TO THIS GROUP ; THESE " HEATED " OR " SMUTTY " GRAINS ARE FULLY GROWN GRAINS IN WHICH THE TEGUMENT IS COLOURED GREYISH BROWN TO BLACK , WHILE THE CROSS-SECTION OF THE KERNEL IS COLOURED YELLOWISH GREY TO BROWNISH BLACK .

GRAINS ATTACKED BY WHEAT-MIDGE SHALL BE CONSIDERED AS DAMAGED GRAINS ONLY WHEN MORE THAN HALF THE SURFACE OF THE GRAIN IS COLOURED GREY TO BLACK AS A RESULT OF SECONDARY CRYPTOGAMIC ATTACK . WHERE DISCOLORATION COVERS LESS THEN HALF THE SURFACE OF THE GRAIN , THE LATTER MUST BE CLASSED WITH GRAINS DAMAGED BY PESTS .

( C ) EXTRANEOUS MATTER :

ALL MATTER IN A SAMPLE OF CEREALS RETAINED BY A SIEVE WITH APERTURES OF 3.5 MILLIMETRES ( WITH THE EXCEPTION OF GRAINS OF OTHER CEREALS AND PARTICULARLY LARGE GRAINS OF THE BASIC CEREAL ) AND THAT PASSING THROUGH A SIEVE WITH APERTURES OF 1 MILLIMETRE SHALL BE CONSIDERED AS EXTRANEOUS MATTER .

ALSO INCLUDED IN THIS GROUP ARE STONES , SAND , FRAGMENTS OF STRAW AND OTHER IMPURITIES IN THE SAMPLES WHICH PASS THROUGH A SIEVE WITH APERTURES OF 3.5 MILLIMETRES AND ARE RETAINED BY A SIEVE WITH APERTURES OF 1 MILLIMETRE .

THIS DEFINITION DOES NOT APPLY TO MAIZE . FOR THAT CEREAL , ALL MATTER IN A SAMPLE WHICH PASSES THROUGH A SIEVE WITH APERTURES OF 1 MILLIMETRE , AS WELL AS ALL THE IMPURITIES MENTIONED IN THE PRECEDING SUBPARAGRAPH , MUST BE CONSIDERED AS EXTRANEOUS MATTER .

( D ) HUSKS ( FOR MAIZE : COB FRAGMENTS )

1 . FOR COMMON WHEAT , DURUM WHEAT , RYE AND BARLEY , AN AVERAGE SAMPLE OF 250 GRAMMES IS PASSED THROUGH TWO SIEVES , ONE WITH APERTURES OF 3.5 MILLIMETRES AND THE OTHER WITH APERTURES OF 1 MILLIMETRE , FOR HALF A MINUTE EACH .

IN ORDER TO ENSURE CONSTANT SIFTING , IT IS ADVISABLE TO USE A MECHANICAL SIEVE , E.G . A VIBRATING TABLE WITH FITTED SIEVES .

THE MATTER RETAINED BY THE SIEVE WITH APERTURES OF 3.5 MILLIMETRES AND THAT PASSING THROUGH THE SIEVE WITH APERTURES OF 1 MILLIMETRE MUST BE WEIGHED TOGETHER AND CONSIDERED AS EXTRANEOUS MATTER . WHERE THE MATTER RETAINED BY THE SIEVE WITH APERTURES OF 3.5 MILLIMETRES INCLUDES PARTS OF THE " OTHER CEREALS " GROUP OR PARTICULARLY LARGE GRAINS OF THE BASIC CEREAL , THOSE PARTS OR GRAINS SHALL BE RETURNED TO THE SIFTED SAMPLE . DURING SIFTING , IN THE SIEVE WITH APERTURES OF 1 MILLIMETRE , A CLOSE CHECK MUST BE MADE FOR LIVE PESTS .

FROM THE SIFTED SAMPLE , A SAMPLE OF 50 TO 100 GRAMMES SHALL BE TAKEN USING A SEPARATOR . THIS PARTIAL SAMPLE MUST BE WEIGHED .

THEN , THIS PARTIAL SAMPLE SHOULD BE SPREAD OUT ON A TABLE WITH TWEEZERS OR A HORN SPATULA AND BROKEN GRAINS , OTHER CEREALS , SPROUTED GRAINS , GRAINS DAMAGED BY PESTS , GRAINS DAMAGED BY FROST , GRAINS IN WHICH THE GERM IS DISCOLOURED , MOTTLED GRAINS , WEED SEEDS , ERGOTS , DAMAGED GRAINS , DECAYED GRAINS , HUSKS AND LIVE PESTS AND DEAD INSECTS MUST BE EXTRACTED .

WHERE THE PARTIAL SAMPLE INCLUDES GRAINS STILL IN THE HUSK , THEY SHALL BE HUSKED BY HAND , THE HUSKS SO OBTAINED BEING CONSIDERED AS PIECES OF HUSKS . STONES , SAND AND FRAGMENTS OF STRAW SHALL BE CONSIDERED AS EXTRANEOUS MATTER .

THE PARTIAL SAMPLE SHALL BE SIFTED FOR HALF A MINUTE IN A SIEVE WITH APERTURES OF 2 MILLIMETRES FOR COMMON WHEAT , 1.8 MILLIMETRES FOR DURUM WHEAT AND 2.2 MILLIMETRES FOR BARLEY . MATTER WHICH PASSES THROUGH THIS SIEVE SHALL BE CONSIDERED AS SHRIVELLED GRAIN . GRAINS DAMAGED BY FROST AND UNRIPE GREEN GRAINS BELONG TO THE " SHRIVELLED GRAINS " GROUP .

2 . FOR MAIZE , AN AVERAGE SAMPLE OF 500 GRAMMES IS SHAKEN FOR HALF A MINUTE IN A SIEVE WITH APERTURES OF 1 MILLIMETRE . CHECK FOR LIVE PESTS AND DEAD INSECTS .

USING TWEEZERS OR A HORN SPATULA , EXTRACT FROM THE MATTER RETAINED BY THE SIEVE WITH APERTURE OF 1 MILLIMETRE , STONES , SAND , FRAGMENTS OF STRAW AND OTHER EXTRANEOUS MATTER .

ADD THE EXTRANEOUS MATTER THUS EXTRACTED TO THE MATTER WHICH HAS PASSED THROUGH THE SIEVE WITH APERTURES OF 1 MILLIMETRE AND WEIGH THEM TOGETHER .

USING A SEPARATOR , PREPARE A SAMPLE OF 100 TO 200 GRAMMES FROM THE SAMPLE PASSED THROUGH THE SIEVE . WEIGH THIS PARTIAL SAMPLE .

SPREAD IT OUT IN A THIN LAYER ON A TABLE . USING TWEEZERS OR A HORN SPATUAL , EXTRACT THE PIECES OF OTHER CEREALS , GRAIN DAMAGED BY PESTS , GRAINS DAMAGED BY FROST , SPROUTED GRAINS , WEED SEEDS , DAMAGED GRAINS , HUSKS , LIVE PESTS AND DEAD INSECTS .

NEXT , PASS THIS PARTIAL SAMPLE THROUGH A SIEVE WITH A 4.5 MILLIMETRE ROUND MESH . MATTER WHICH PASSES THROUGH THIS SIEVE SHALL BE CONSIDERED AS BROKEN GRAINS .

3 . GROUPS OF MATTER OTHER THAN BASIC CEREALS OF UNIMPAIRED QUALITY , DETERMINED ACCORDING TO THE METHODS REFERRED TO IN 1 AND 2 , THE PERCENTAGES OF WHICH ARE LAID DOWN IN ARTICLE 1 TO 5 , MUST BE WEIGHED VERY CAREFULLY TO THE NEAREST 0.01 GRAMMES AND DISTRIBUTED ACCORDING TO PERCENTAGE OVER THE AVERAGE SAMPLE . THE PARTICULARS ENTERED IN THE ANALYSES REPORT SHALL BE TO THE NEAREST 0.1 % . CHECK FOR LIVE PESTS .

AS A GENERAL RULE , TWO ANALYSES MUST BE MADE FOR EACH SAMPLE . THEY MUST NOT DIFFER BY MORE THAN 10 % IN RESPECT OF THE TOTAL OF THE ABOVEMENTIONED MATTER .

4 . THE APPARATUS TO BE USED FOR THE OPERATIONS REFERRED TO IN 1 , 2 AND 3 IS AS FOLLOWS :

( A ) SAMPLE SEPARATOR , E.G . A CONICAL OR GROOVED APPARATUS ;

( B ) PRECISION OR ASSAY BALANCE ;

( C ) SIEVES WITH APERTURES OF 1 MILLIMETRE , 1.8 MILLIMETRES , 1.9 MILLIMETRES , 2 MILLIMETRES , 2.2 MILLIMETRES , AND 3.5 MILLIMETRES AND A SIEVE WITH A 4.5 MILLIMETRE ROUND MESH . THE SIEVES MAY BE FITTED TO A VIBRATING TABLE .

ANNEX II

STANDARD METHOD OF TESTING FOR MOISTURE CONTENT

1 . PRINCIPLE :

THE PRODUCT IS DRIED AT A TEMPERATURE OF 130 TO 133 * C , UNDER NORMAL ATMOSPHERIC PRESSURE , FOR A PERIOD OF TIME FIXED BY RULE OF THUMB ACCORDING TO THE SIZE OF THE PARTICLES .

2 . FIELD OF APPLICATION :

THIS DRYING METHOD APPLIES TO CEREALS CRUSHED INTO PARTICLES OF WHICH AT LEAST 50 % PASS THROUGH A SIEVE WITH 0.5 MILLIMETRE MESH AND LEAVE NOT MORE THAN 10 % RESIDUE ON THE SIEVE WITH A 1 MILLIMETRE ROUND MESH .

IT ALSO APPLIES TO FLOUR .

3 . APPARATUS :

PRECISION BALANCE .

CRUSHER MADE OF A MATERIAL WHICH DOES NOT ABSORB MOISTURE , IS EASY TO CLEAN , ENABLES CRUSHING TO BE EFFECTED QUICKLY AND EVENLY WITHOUT OVERHEATING , LIMITS CONTACT WITH THE OUTSIDE AIR TO THE MINIMUM , AND MEETS THE REQUIREMENTS MENTIONED IN 2 ( E.G . A DETACHABLE ROLLER MILL ) .

RECEPTACLE MADE OF NON-CORRODIBLE METAL OR GLASS , FITTED WITH A GROUND LID ; WORKING SURFACE ALLOWING DISTRIBUTION OF THE TEST SAMPLE AT 0.3 GRAMMES PER SQUARE CENTIMETRE .

ELECTRICALLY HEATED ISOTHERMIC HEATING CHAMBER , SET AT A TEMPERATURE OF 130 TO 133 * C ( 1 ) , HAVING ADEQUATE VENTILATION ( 2 ) .

DRYER WITH A METAL OR , FAILING METAL , PORCELAIN PLATE , THICK , PERFORATED , CONTAINING SILICA GEL IMPREGNATED WITH COBALT CHLORIDE OR ANY OTHER SUITABLE DEHYDRATOR .

4 . METHOD :

( A ) DRYING :

WEIGH AT LEAST 5 GRAMMES OF THE CRUSHED SUBSTANCE IN THE PRE-WEIGHED RECEPTABLE . PLACE THE RECEPTABLE IN A HEATING CHAMBER HEATED TO 130 * C . TO PREVENT TOO GREAT A DROP IN TEMPERATURE THE RECEPTACLE MUST BE INTRODUCED IN AS SHORT A TIME AS POSSIBLE . LEAVE TO DRY FOR TWO HOURS AFTER THE HEATING CHAMBER REGAINS A TEMPERATURE OF 130 * C . REMOVE THE RECEPTACLE FROM THE HEATING CHAMBER , QUICKLY REPLACE THE LID , LEAVE TO COOL FOR 30 TO 45 MINUTES IN A DRYER AND WEIGH ( WEIGHING MUST BE ACCURATE TO 1 MILLIGRAMME ) .

( B ) PRE-DRYING :

GRAINS WITH A MOISTURE CONTENT HIGHER THAN 17 % MUST BE PRE-DRIED AS FOLLOWS :

WEIGH 50 GRAMMES OF UNGROUND GRAIN IN A SUITABLE RECEPTACLE ( E.G . A 20 BY 12 CENTIMETRE ALUMINIUM PLATE WITH A 0.5 CENTIMETRE RIM ) , LEAVE TO DRY IN A HEATING CHAMBER FOR SEVEN TO TEN MINUTES AT A TEMPERATURE OF 130 * C , REMOVE FROM THE HEATING CHAMBER , LEAVE THE GRAINS UNCOVERED TO COOL IN THE LABORATORY FOR TWO HOURS AND WEIGH ( WEIGHING MUST BE ACCURATE TO 10 MILLIGRAMMES ) . CRUSH THE PARTIALLY DRIED GRAINS AND DETERMINE THE REMAINING MOISTURE CONTENT AS DESCRIBED IN ( A ) .

5 . METHOD OF CALCULATION AND FORMULAE : ( SEE O.J . NO L 281 OF 1 . 11 . 75 )

6 . ACCURACY OF TEST :

THE DIFFERENCE BETWEEN TWO TESTS MADE ON THE SAME SAMPLE MUST NOT EXCEED MORE OR LESS 0.1 % OF MOISTURE .

( 1 ) AIR TEMPERATURES INSIDE THE HEATING CHAMBER .

( 2 ) ITS HEATING CAPACITY SHOULD BE SUCH THAT , WHEN IT HAS BEEN PRE-SET TO 131 * C , THAT TEMPERATURE CAN BE REGAINED IN LESS THAN 45 MINUTES AFTER THE MAXIMUM NUMBER OF TEST SAMPLES HAVE BEEN PLACED IN THE CHAMBER TO DRY SIMULTANEOUSLY , VENTILATION SHOULD BE SUCH THAT , WHEN ALL TEST SAMPLES OF COMMON WHEAT IT CAN HOLD ARE DRIED FOR TWO HOURS , THE RESULTS DIFFER BY NO MORE THAT 0.15 % FROM THE RESULTS OBTAINED AFTER DRYING FOR FOUR HOURS .
