- Boosts credibility and tender eligibility.
- Needs regular renewal and compliance upkeep.
Introduction
A Delhi-based cable manufacturer recently faced shipment delays when its armouring wires were rejected for lacking BIS certification. The issue stalled an entire project and exposed a gap many manufacturers overlook—compliance with Indian Standards. For low carbon galvanized steel wires, formed wires, and tapes used in cable armouring, certification isn’t optional but a legal and quality requirement. It assures customers of reliability, durability, and safety. In India’s power and telecom sectors, BIS certification now defines who can compete and who gets left behind. Bureau of Indian Standards
What is IS 3975:1999?
IS 3975:1999 defines the standards of quality and performance for low carbon galvanized steel wires, formed wires, and tapes used in cable armouring. By doing so, it makes sure that the metal materials used as a protective layer for electrical and communication cables are durable, consistent, and resistant to rust.
Key points:
- Specifies chemical composition of low carbon steel
- Defines size, shape, and tolerance limits for wires and tapes
- Sets requirements for zinc coating mass and adhesion
- Includes mechanical tests for strength, wrapping, and torsion
- Ensures long-term safety and durability of armoured cables. ISI MARK
Importance and Benefits of BIS Certification
| Importance | Benefits |
| Ensures product quality and safety compliance | Builds customer trust and brand credibility |
| Mandatory for market approval under BIS Act | Enables participation in government tenders |
| Prevents sale of substandard or unsafe materials | Reduces rejection, warranty, and liability risks |
| Promotes standardization across industries | Increases market access and export opportunities |
| Protects consumer interests and public safety | Enhances business reputation and competitiveness |
Why is BIS Certification Mandatory
BIS certification is mandatory to ensure that products sold or used in India meet defined safety, quality, and performance standards. As an example, in a case of low carbon galvanized steel wires, formed wires, and tapes for cable armouring, the certification is a safety assurance to both the manufacturers and the consumers as a result of the implementation of the same quality standard throughout the market.
Key points:
- Ensures compliance with Indian Standards under the BIS Act, 2016
- Prevents the sale of substandard or unsafe materials
- Builds customer trust and credibility in the supply chain
- Required for participation in government and infrastructure tenders
- Helps avoid legal penalties, shipment rejection, or market restrictions
Step-by-Step Process of BIS Certification
Step1:Documentation
- Collect manufacturing details, product specifications, and process flow.
- Prepare the quality control records, test equipment lists, and calibration certificates.
- Ensure that the traceability of raw materials is quite transparent and that the suppliers are going to meet the requirements.
- Make sure that all the documents are in line with the respective Indian Standard requirements.
Step2:Product Testing
- Product samples must be sent to a laboratory that is BIS-certified for testing.
- Ensure that the tests cover all the parameters – mechanical, chemical, and coating quality.
- Receive a complete test report indicating that the product meets the IS standards.
- If there are any non-conformities, settle them before proceeding with the application submission.
Step3:Application Submission
- Fill out the BIS online application accurately with product details and test results.
- Attach supporting documents such as factory layout, lab setup, and quality plan.
- Pay the prescribed application and testing fees.
- Submit the application to the concerned BIS regional office for review.
Step4:Scrutiny and Inspection
- BIS officials examine submitted documents and verify test reports.
- An on-site inspection is conducted to assess production and quality systems.
- Samples may be drawn again during inspection for independent verification.
- Any discrepancies are reported for correction before licence approval.
Step5:Grant of License
- BIS issues the licence after successful compliance verification.
- The manufacturer is authorised to use the Standard Mark (ISI mark) on certified products.
- Each batch must be tested and recorded under the defined control unit.
- Regular surveillance audits ensure continued adherence to BIS standards.
Documents Required for BIS Certification
| Document Type | Details Required |
| Application Form | Duly filled BIS application with product details |
| Test Reports | Product test results from BIS-recognized lab |
| Manufacturing Details | Process flow chart, equipment list, and QC plan |
| Factory Layout | Plant layout showing production and testing areas |
| Raw Material Records | Supplier certificates and traceability documents |
| Quality Control Records | Calibration, inspection, and test data logs |
| Legal Documents | Company registration, GST, and authorization letter |
| Declaration Form | Undertaking of conformity to relevant Indian Standard |
Timelines, Costs, Validity & Renewal
- Timelines: Most of the work gets done within 4 to 6 weeks, and is also dependent on the tests and paperwork.
- Costs: The cost is the sum of the application, testing, and the annual licence fees which vary with the product type.
- Validity: The licence is still valid for two years from the day it was given.
- Renewal: It may be renewed for up to five years (with) new test reports and renewal fee payments.
