PD CEN/TS 17685-2:2024


This standard PD CEN/TS 17685-2:2024 Earthworks. Chemical tests is classified in these ICS categories:
  • 13.080.99 Other standards related to soil quality
  • 93.020 Earthworks. Excavations. Foundation construction. Underground works
This document describes a method for the determination of the oxidizable organic matter content of a soil, which is mainly composed of fresh organic matter and fulvic and humic acids, by back titration with potassium permanganate. The result obtained with this technical specification is not comparable with those obtained by EN 17685-1:2023 (loss on ignition).
