- High-strength steel bars and wires for concrete use require a BIS certification under IS 1786:2008.
- It is a comprehensive process involving factory audits, testing, and BIS surveillance to maintain the quality.
- The standard specifies the aspects of the product such as grades, high-strength deformed steel, elongation, and dimensional tolerances.
- Certified bars are safe, durable, and compliant with the regulations which are advantageous to builders and clients.
- It is always a good practice to check the ISI mark, BIS licence number, and test certificates before using the product.
Introduction
A project at a site in Delhi came to a stop after the reinforcements bars delivered were found not to have the BIS mark. Low yield strength was revealed by the tests, thus a replacement had to be made at a high cost. Such are the instances that explain why certified steel is the most essential element in the safety of the structure. BIS Certification for High Strength Deformed Steel Bars and Wires for Concrete Reinforcement as per IS 1786:2008 is the way to ensure that each bar is up to the mark in terms of strength, ductility, and quality.

What is IS 1786:2008?
IS 1786:2008 is a standard that defines the attributes of a good product, its strength, and how the product is tested for high tensile strength, deformed steel bars and wires used for reinforced concrete. In other words, this is the standard that guarantees the safety, ductility, and reliability of the structural use of rebar in the construction of buildings or any other types of structures.
Key Points:
- It is a standard establishing the quality requirements set up by the Bureau of Indian Standards (BIS) for structures made of reinforced concrete.
- The document specifies the geometry and chemistry of the four grades of iron 415, 500, 550, and 600.
- In addition to the chemical composition, the standard also determines the mechanical strength and the elongation percentage.
- The final elements that are limited by this standard are those which are verified by the tests of bending, rebending, and measuring the surface deformations of the samples.
- It also permits very accurate dimensions, quality uniformity, and corrosion resistance as well. ISI MARK
Why is BIS Certification Mandatory
The main purpose of mandatory BIS certification for high-strength deformed steel bars and wires under IS 1786:2008 is to ensure that the reinforcement materials used in concrete are safe and of high quality. It is a measure that supports the safety of the public, the quality of construction, and impedes the flow of substandard steel in the market.
Key Points:
- It is the main instrument to ensure adherence to national standards of safety and quality for construction materials.
- It is a barrier for counterfeit or low-grade products to get into the market of reinforcement bars.
- It is obligatory under the Quality Control Order (QCO) issued by the Ministry of Steel.
- Facilitates the uniformity and reliability of standards between the different manufacturers and projects.
- It is an instrument that creates the trust and the confidence of engineers, builders, and consumers that the steel is going to be as strong as per IS 1786:2008 standards.

Step-by-Step Process of BIS Certification
Step1:Documentation
- Collect company registration, manufacturing details, and process flow charts.
- Prepare quality control plans and product specifications per IS 1786:2008.
- Include test reports, calibration certificates, and lab details (in-house or NABL).
- Ensure all documents are accurate, signed, and ready for BIS scrutiny.
Step2:Product Testing
- Product samples should be taken to a laboratory that is either BIS-recognized or NABL-accredited for testing.
- Along with chemical and mechanical tests, a bend and rebend should also be performed as per IS 1786:2008.
- Obtain a detailed test report indicating the product’s conformity to the standard.
- Save the records of all the tests along with the BIS certificate for the future reference.
Step3:Application Submission
- Submit the online application through the BIS portal with complete documentation.
- Pay application and testing fees as per the current BIS fee structure.
- Mention product type, grade, and sizes to define the licence scope.
- Upload the lab test report and quality documents for preliminary verification.
Step4:Scrutiny and Inspection
- BIS officials review the documents and test results for compliance.
- A factory inspection is conducted to assess manufacturing and quality systems.
- Inspectors verify raw materials, equipment, testing facilities, and record keeping.
- Any non-conformities must be corrected before final approval.
Step5:Grant of Licence
- Once inspection and testing are approved, BIS issues the licence.
- The manufacturer can now use the Standard Mark (ISI mark) on certified products.
- The licence specifies the product scope, grades, and valid period.
- Regular surveillance audits ensure continued conformity and licence renewal.
