The BIS Certification for Sodium Hypochlorite Solution for Water Treatment (IS 11673 (Part
2):2019) is one of the requirements that need to be met by the manufacturers who supply the
disinfectant solution in the municipalities' water systems as well as industrial treatment centers.
The choice of sodium hypochlorite for the process of water treatment is because the solution is
effective in ensuring that the hazardous microorganisms are killed while maintaining water
quality.
The increase in focus on water safety makes it critical for manufacturers to ensure that their
products meet the prescribed specifications consistently. For instance, obtaining the certification
as per IS 11673 (Part 2):2019 includes product testing, quality check, documentation validation,
as well as conformity assessment. This ensures that the products meet the necessary
specifications for use in water treatment.

BIS Testing Requirements for Sodium Hypochlorite Solution
Water Treatment Use
To ensure safe and effective use of sodium hypochlorite in water treatment applications, BIS has
established quality standards under IS 11673 (Part 2):2019. This certification ensures that the
chemical meets required disinfection efficiency, purity levels, and stability parameters for potable
and industrial water systems.
The BIS testing parameters and quality checks for the sodium hypochlorite solution are listed
below:
Step-by-Step BIS Certification Process for IS 11673 (Part
2):2019
The BIS Authorisation process ensures that Sodium Hypochlorite Solution (IS 11673 Part
2:2019) meets the required standards for safe and effective use in water treatment applications.
This process includes the following steps:
- Online Registration:Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for moisture content, fibre level, purity, nutritional composition and absence of contaminants.
- Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
- Factory Inspection: Officials from the BIS come to the manufacturing unit to evaluate production processes, safety measures, and the quality control system.
- Grant of BIS License: Once all compliance procedures have been satisfactorily met, the certification license is granted by BIS under Scheme I.
- Use of ISI Mark: Following approval, the manufacturer is authorized to use the ISI Mark on the product along with a valid CM/L number, confirming that the product meets BIS standards.
