ISO/FDIS 11465

Sludge and solid environmental matrices — Determination of dry residue or water content and calculation of the dry matter fraction on a mass basis

General information

50.20     Jun 2, 2025

ISO

ISO/TC 190/SC 3

International Standard

13.080.20  

Scope

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.
