GB/T 34322-2017 Automatic continuous determination of water quality for boiler and cooling system—Potentiometric titration

Scope

This standard specifies the automatic continuous measurement methods for electrical conductivity, pH, phenolphthalein alkalinity, total alkalinity, chloride ions, and hardness in water used for industrial boilers, circulating cooling water, and natural water. The measurement range applicable to this standard is: electrical conductivity of 10 μS/cm to 10 mS/cm; pH of 3 to 13; phenolphthalein alkalinity of 0 mmol/L to 30 mmol/L; total alkalinity of 0.2 mmol/L to 50 mmol/L; chloride ions of 5 mg/L to 1,500 mg/L; and hardness (calculated as Ca2+ and Mg2+) of 0.015 mmol/L to 15 mmol/L.
