Le présent document spécifie des méthodes de calcul de la fraction de matière sèche des boues, biodéchets traités, sols et déchets pour lesquels les résultats de l'analyse réalisée doivent être rapportés à la matière sèche. Selon la nature et l'origine de l'échantillon, le calcul est basé sur une détermination du résidu sec (méthode A) ou une détermination de la teneur en eau (méthode B) . Il s'applique à des échantillons contenant plus de 1 pour cent (fraction massique) de résidu sec ou plus de 1 pour cent (fraction massique) d'eau. La méthode A s'applique aux boues, biodéchets traités, sols et déchets solides, la méthode B s'applique aux déchets liquides et aux échantillons suspectés ou connus pour contenir des substances volatiles autres que l'eau.
