Water is tested to the IS 3025 series for pH, conductivity, turbidity, colour and odour, total dissolved solids, hardness, alkalinity and acidity, chlorides, sulphate and dissolved oxygen. Metals including arsenic, cadmium, chromium, lead, iron, manganese, nickel, selenium and zinc are measured by ICP to APHA 3120.

RO water purifiers are tested for microbiological reduction of E. coli, MS-2 coliphage, Cryptosporidium and Giardia to IS 16240.
