ISI Mark Certification Process for Steel Tubes under IS 4270:2001
Steel pipes used for water wells must undergo the BIS certification process to ensure that they satisfy the requirements set out in IS 4270:2001. The BIS certification process involves 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 mechanical strength, dimensional accuracy, wall thickness, material composition, hydrostatic pressure resistance and corrosion resistance.
- 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 - BIS officials carry out an on-site inspection of the manufacturing unit to verify the production process, safety measures and quality control system.
- Grant of BIS License - Once all compliance requirements are satisfactorily verified, BIS grants the certification license under Scheme-I.
- Use of ISI Mark - After approval, the manufacturer is permitted to use the ISI Mark on the product along with a valid CM/L number, confirming that the product meets BIS standards.
