If such conditions (cloudiness, formation precipitates) are observed, wells containing the next lesser concentrations are examined as well (and so forth) and concentrations that did not completely go into solution are to be excluded from further evaluation and analysis.
Si l'on observe ce phénomène (opacité, formation de précipités), on examine aussi les puits contenant la concentration immédiatement inférieure (et ainsi de suite) et il faut exclure de la suite de l'évaluation et de l'analyse les concentrations non complètement dissoutes.
