This document specifies a method for the gravimetric determination of soil water content as a volume fraction.

The method is applicable to all types of non-swelling or non-shrinking soils where coring sleeves can be used for sampling. It is not applicable to soils where stones, tough roots or other factors prevent collection of soil cores. It is used as a reference method (e.g. the calibration of indirect methods for determination of water content).

NOTE The determination of water content as a mass fraction is described in ISO 11465.

This document specifies a method for the determination of mercury in digests of soil, treated biowaste, sludge and waste, obtained according to EN 16173 (nitric acid digestion), EN ISO 54321 (aqua regia digestion) or EN 13656 (digestion with a hydrochloric (HCl), nitic (HNO3) and tetrafluoroboric (HBF4) or hydrofluoric (HF) acid mixture) with using cold-vapour atomic absorption spectrometry (CV-AAS). The lower working range limit is at least 0,03 mg/kg (dry matter basis) depending on digestion parameters.
