GB/T 32208-2015 "Chemical Oxygen Demand (COD) Analyzers" specifies the technical requirements, test methods, inspection rules, marking, packaging, and other aspects of chemical oxygen demand (COD) analyzers. It applies to the determination of chemical oxygen demand in water quality. The instrument processes samples through catalytic oxidation or digestion, calculates the COD value based on corresponding detection principles, and must meet performance indicators such as repeatability, accuracy, and stability. The detection requires standard substances, constant-temperature water baths, and analytical balances, providing a standardized basis for COD detection equipment in fields such as water quality monitoring and environmental management.
