Soil quality. Acid-base accounting procedure for acid sulfate soils - Chromium reducible sulfur (CRS) methodology Ingestion-build-209208 BS EN 620:2002 covers the1 Scope This part of ISO 14388 specifies a suite of methods used to determine the net acidity in acid sulfate soils. This part of ISO 14388 specifies a method for measuring chromium reducible sulfur (SCR) by iodimetric titration of distilled hydrogen sulfide trapped as zinc sulfide, following acidic chromous chloride digestion. This method determines inorganic sulfides (e. g. pyrite, marcasite, greigite, mackinawite) and elemental sulfur in acid
