• Initial Type Testing (S) - Conducted before BIS certification approval.
• Surveillance Testing (S) - Ensures continued compliance during license validity.
• Grade Rotation Testing (S) - Ensures all sizes and variants are periodically tested.

• Physical Test Sampling (R) - Based on lot size using IS 4905 random sampling.
• Chemical Test Sampling (R) - Conducted from physically accepted samples.
• Lot Acceptance Criteria (R) - Lot accepted only when all physical and chemical requirements are satisfied.

The BIS Authorisation process ensures that the wire meets 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 labs 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.
