Water quality. Determination of the chemical oxygen demand index (ST-COD). Small-scale sealed-tube method Ingestion-build-51215 surface area per unit volume1 Scope This International Standard specifies a method for the determination of the chemical oxygen demand (ST COD) using the sealed tube method. The test is empirical and is applicable to any aqueous sample, which includes all sewage and waste waters. The method is applicable to undiluted samples having ST COD values up to 1 000 mg l and a chloride concentration not exceeding 1 000 mg l. Samples with higher ST COD values require predilution. For
