( 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 .

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 .
