The BIS certification process ensures that the flexible irrigation pipes meet the required standards for proper and efficient operation. This process is set by the Bureau of Indian Standards (BIS) and includes the following steps:

1. 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).
2. Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for material safety and structural durability.
3. Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
4. Factory Inspection: BIS officials inspect the manufacturing unit to verify the production process, safety measures, and quality control system.
5. Grant of BIS License: If all requirements are met, BIS grants the certification license under Scheme-I.
6. Use of ISI Mark: After approval, the manufacturer can use the ISI mark on the product with a CM/L number, confirming that the product meets BIS standards.
