Sludge, treated biowaste, soil and waste - Determination of dry residue or water content and calculation of the dry matter fraction on a mass basis (ISO/DIS 11465:2024)

The method specified can be applied to all types of soil samples. Different procedures are specified for air-dried soil samples, e.g. samples pretreated according to ISO 11464, and for field-moist soil samples. Its principle is drying soil samples to constant mass at 105 °C and using the difference in mass of an amount of soil before and after the drying procedure to calculate the dry matter and water contents on a mass basis. For the determination of soil water content on a volume basis, refer to ISO 11461.

Boues, biodéchets traités, sols et déchets - Détermination de la teneur en résidu sec ou en eau et calcul de la fraction massique de matière sèche (ISO/DIS 11465:2024)

La présente Norme internationale prescrit une méthode de détermination de la teneur pondérale en matière sèche et en eau d'échantillons de sol. Cette méthode peut être appliquée à tous les types d'échantillons de sol. La marche à suivre diffère selon qu'il s'agit d'échantillons de sol séchés à l'air, par exemple les échantillons préalablement traités conformément à l'ISO 11464, ou d'échantillons de sol dont le taux d'humidité est celui de leur lieu de prélèvement. Pour la détermination de la teneur en eau volumique du sol, consulter l'ISO 11461.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent
rights identified during the development of the document will be in the Introduction and/or on the ISO list of
patent declarations received (see www.iso.org/patents).

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.

— content was merged with the content of EN 12880 where appropriate;
— content was merged with the content of EN 15934 where appropriate;
— deletion of the informative Annex “Azeotropic distillation with toluene”;
— editorially revised.
