Rispri Laboratory · NABL & ISO/IEC 17025:2017 Accredited
Comprehensive analytical testing for drinking water (IS 10500), packaged water (IS 14543), ETP/STP industrial effluent compliance, heavy metal ICP-OES profiling, and organic BOD/COD characterization.
IS 10500 / IS 14543 Standards
Full-spectrum physical, chemical, and microbiological analysis of drinking water, borewell supply, municipal tap water, commercial RO water, and packaged drinking water as per Indian Standards (IS 10500:2012 & IS 14543).
Unchecked drinking water parameters present acute health risks, regulatory non-compliance for food & beverage manufacturers, and severe scaling/corrosion in commercial plumbing systems.
