navedla je, da so grudice silicija nato pred izvozom na trg unije prečiščene, zdrobljene, presejane in ponovno zapakirane v vreče.
the sieved residues are weighed to the nearest 0,1 g and expressed as a percentage of the sieved product which shall be weighed to the nearest whole number, and the average calculated.
ostanki sejanja se stehtajo z natančnostjo 0,1 g in izrazijo v odstotkih stehtanega presejanega proizvoda kot cela števila, potem se izračuna povprečje.
the oil retention, from each determination (6.0) expressed as a percentage by mass of the sieved test portion, is given by the equation:
zadrževanje olja se iz vsakega določanja (6.0) izrazi kot masni odstotek presejanega preskusnega deleža in zračuna po enačbi:
immediately transfer all the sieved sample to an air-tight container of sufficient capacity (twice volume of sample) and mix thoroughly by repeated shaking and inverting.

the part of the final sample referred to under 4.2 and 4.3 is sieved rapidly through a sieve with apertures of 0 75 mm. the residue is ground roughly so as to obtain a product in which there is a minimum of fine particles, and it is then sieved.
delež končnega vzorca, navedenega v 4.2 in 4.3, se hitro preseje skozi sito z 0,5-milimetrskimi luknjicami. preostanek se grobo zmelje, tako da se dobi produkt, v katerem je najmanjše možno število delcev in ki se nato zmelje.
