Short answer: match the test to who is asking for the report. A municipal inspector, an FSSAI auditor and a housing society committee each want a different standard.
| If you are… | Ask for | Standard |
|---|---|---|
| A housing society with complaints about tank water | Full drinking water panel, tank and tap | IS 10500 |
| A packaged drinking water plant renewing a BIS licence | Full packaged water panel on sealed packs | IS 14543 |
| A restaurant preparing for an FSSAI inspection | Drinking water panel plus ice and surface swabs | IS 10500 + micro |
| A factory renewing its consent to operate | Effluent discharge panel for your route | CPCB / WBPCB |
| A builder about to pour reinforced concrete | Chloride, sulphate, pH, solids, organic matter | IS 456 |
| A household that just wants to know if it is safe | Coliform, E. coli, pH, TDS, hardness, iron | IS 10500 subset |
