PD CEN/TS 17685-5:2026

This standard PD CEN/TS 17685-5:2026 Earthworks. Chemical tests is classified in these ICS categories:

• 13.080 Soil quality. Pedology
• 93.020 Earthworks. Excavations. Foundation construction. Underground works
• 13.080.99 Other standards related to soil quality

The purpose of this document is to describe a gravimetric method for the determination of the water-soluble salt content (WSS) in soils. These salts typically comprise inorganic ions such as sulphates, chlorides, nitrites, nitrates, bicarbonates, sodium, ammonium, calcium, magnesium, and strontium. The method involves initial dissolution in demineralized water and subsequent determination of the mass of the residue obtained by evaporation. The results obtained in accordance with this document do not represent the total salt content of the soil, but exclusively the fraction soluble in water under the specific conditions defined in this document. These results are not comparable with those obtained by CEN/TS 17685 4:2026, relative to the determination of water-soluble sulphate content in soils.
