- BIS certification under IS 6006:2014 is required for Uncoated stress-relieved strand.
- It provides verification for quality, strand bonding strength, and safety in prestressed concrete.
- BIS certification under IS 6006:2014 also provides for continual surveillance by BIS.
- BIS certified strands provide you with peace of mind that the project will be untapped and also prevents rejections at the job site.
- It is always important to check that the supplier has a valid BIS licence and that the product has been marked properly before ordering.
Introduction
A significant flyover construction project in Pune went on hold because one batch of steel strands was rejected for not having a BIS certificate for IS 6006:2014, despite the fact that they met the strength standard; the lack of a BIS licence caused delays and penalties. Today in India, a BIS certificate is required for uncoated stress-relieved strands for the production of prestressed concrete. The purpose of a BIS certification is to ensure national standards of safety and durability are satisfied for the materials used in construction. For the manufacturers and contractors, a BIS certificate is more than compliance; it is the quality, credibility, and assurance of project continuity.
What is IS 6006:2014?
IS 6006:2014 details the necessary quality and performance features of the single-layer, basically relaxed, uncoated steel strands used in the construction of prestressed concrete structures, etc. The Indian standards issued by BIS (Bureau of Indian Standards) aim at maintaining the strength, ductility, and durability of these strands at a uniform level for structural safety and reliability.
Key Points:
- Specifies chemical composition, tensile strength, and dimensional limits of strands.
- Requires stress relieving of strands to improve mechanical stability and reduce loss of stress.
- Specifies testing for breaking strength, elongation, and relaxation characteristics.
- Provides marking and traceability standards in regard to identification and quality control.
- Materials used in the construction of bridges, flyovers, and precast elements will conform to BIS safety norms. ISI MARK
Why is BIS Certification Mandatory
- Legal Requirement: Mandated under the BIS Act, 2016 and Quality Control Orders (QCOs).
- Ensures Quality: Confirms strands meet IS 6006:2014 mechanical and chemical standards.
- Safety Assurance: Prevents structural risks in prestressed concrete projects.
- Market Eligibility: Required for supply in government and private infrastructure tenders.
- Traceability: BIS mark guarantees authenticity and compliance of materials.
Importance & Benefits of BIS Certification
| Importance | Benefits |
| Compliance with National Standards | Ensures uncoated stress-relieved strands meet all technical and mechanical requirements of IS 6006:2014. |
| Mandatory Regulatory Approval | Legally authorises manufacturers to produce and sell within India under the BIS Act, 2016. |
| Structural Safety Assurance | Guarantees reliable performance of prestressed concrete elements, reducing risks of failure. |
| Market and Tender Eligibility | Allows participation in government and infrastructure projects that accept only BIS-certified materials. |
| Consumer and Industry Confidence | Builds trust among clients, engineers, and contractors by demonstrating verified product quality. |
| Quality and Traceability Control | Provides consistent production monitoring, factory audits, and traceable marking for accountability. |
Step by Step process of BIS Certification
Step1:Documentation
- Gather information on company registration, manufacturing licence, and layout of factory.
- Make a detailed list of machinery, quality control equipment, and test lab used for testing.
- Keep internal test reports and calibration records for all instruments in place.
- Ensure that the documentation is in line with BIS instructions for IS 6006:2014.
Step2:Product Testing
- Submit the product samples to a BIS registered laboratory for testing.
- Testing results will consist of the chemical composition, tensile strength, elongation, and relaxation according to IS 6006:2014.
- All tested samples must have traceability to production batch numbers.
- Obtain a certified lab test report to attach with the BIS application.
Step3:Application Submission
- Apply online through the BIS portal (Manakonline or Smart Registration).
- Upload all supporting documents, test reports, and factory details.
- Clearly mention product scope (strand size, wire count, class).
- Pay the required application and processing fees before submission.
Step4:Scrutiny and Inspection
- BIS officials review submitted documents and lab reports for completeness.
- A factory inspection is conducted to verify manufacturing capability and quality systems.
- Samples may be drawn for witness testing during the audit.
- Address any non-conformities identified during scrutiny before final approval.
Step5:Grant of License
- Once all tests and inspections are satisfactory, BIS issues the licence.
- The manufacturer receives a unique BIS licence number.
- Products can now display the Standard Mark (ISI mark) with licence details.
- Maintain ongoing compliance and prepare for periodic surveillance audits by BIS.
