- Guarantee of compliance with BIS standards for water well steel pipes
- Increase in structural strength and load-carrying capacity
- Improved resistance to corrosion in underground and wet environments
- Improved durability and service life
- Decreased possibility of failure of the pipes in borewells
- Improved reliability in water pumping systems
- Compliance with relevant BIS QCO standards
- Greater acceptability in government water projects
- Standardized production procedures according to IS 4270:2001
- Improved safety and efficiency in water wells
BIS Testing Requirements as per IS 4270:2001
To ensure consistent performance of steel tubes used in water wells, including borewells and tube wells for groundwater extraction, the Bureau of Indian Standards outlines the minimum requirements under BIS IS 4270: 2001. This certification ensures that manufacturers produce steel tubes with adequate strength for long-term use.
The BIS testing parameters and quality checks for the steel tubes are listed below:
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.
