- Before Mild Steel can be used for concrete reinforcement, BIS certification under IS 432 Part 1:1982 is required.
- The standard is a safety and quality measure that specifies the product’s chemical, mechanical, and dimensional requirements.
- Producers are obliged to perform tests on the samples, have a BIS inspection, and then get the ISI mark.
- The certified products have an advantage in gaining the trust of the market and being considered eligible for tenders.
- It is necessary to carry out regular audits and quality checks if the certification is to remain valid.
Introduction
The construction of a major infrastructure project in Mumbai was halted at a point in time because the reinforcement bars that were given as the material lacked BIS certification according to the IS 432 Part 1:1982. Even though the bars met the strength requirements, they could not be approved for load-bearing structures. Such a circumstance is typical for suppliers who are ignorant of the fact that certification is a legal requirement for reinforcement steel. BIS certification is a way to ensure that mild steel and medium tensile steel bars are of the required quality, safety, and performance standards as per those set by the Bureau of Indian Standards.
What is IS 432 Part 1:1982?
IS 432 Part 1:1982 is an Indian Standard that specifies the technical and quality requirements for mild steel and medium tensile steel bars used in concrete reinforcement. It ensures that reinforcement bars used in construction are strong, ductile, and safe for structural applications.
Key Points:
- Issued by the Bureau of Indian Standards (BIS) for plain steel bars used in reinforced concrete.
- Defines chemical composition, mechanical properties, and dimensional tolerances.
- Covers two grades: Mild Steel and Medium Tensile Steel.
- Specifies testing procedures such as tensile and bend tests.
- Mandatory BIS certification ensures quality and legal compliance before sale or use. ISI MARK
Why is BIS Certification Mandatory
- Steel rods are ensured to be up to the safety and quality standards set by IS 432 Part 1:1982.
- It stops the use of poorly graded or fake metal reinforcements.
- Provides the required strength and resistance of the structure in the building process.
- Very essential as per BIS Quality Control Orders (QCOs).
- Helps the construction professionals such as engineers, builders, and clients to put their trust in the project.
Importance & Benefits of BIS Certification
| Importance | Benefits |
| Ensures compliance with IS 432 Part 1:1982 standards | Guarantees product safety and reliability in construction. |
| Mandatory under BIS Quality Control Orders | Helps avoid legal penalties and product rejection. |
| Confirms material quality and performance | Builds trust among clients and project authorities. |
| Establishes standard manufacturing practices | Improves production efficiency and consistency. |
| Protects end users and infrastructure safety | Enhances brand reputation and customer confidence. |
| Validates authenticity of steel products | Increases eligibility for government and private tenders. |
Step-by-Step Process of BIS Certification
Step1:Documentation
- Gather details related to the manufacturing, process flow, and product specifications.
- Organize quality control and test records of the internal processes.
- Make sure that calibration certificates for laboratory equipment are not expired.
- Align all documents in the formats as prescribed by BIS prior to submission.
Step2:Product Testing
- Product samples should be sent to a laboratory certified by BIS.
- Tests are performed according to the Indian Standard that is applicable (e.g., IS 432 Part 1:1982).
- Confirm that all the factors, for instance, the chemical and the mechanical ones, are also included in the verification process.
- Get the full test report together with the laboratory accreditation details.
Step3:Application Submission
- File your BIS application in an online mode through the official BIS portal.
- Remember to submit all the necessary documents such as test reports and proof of factory setup along with the application.
- Pay the government and processing fees that are applicable.
- Use the BIS registration dashboard to check your application status.
Step4:Scrutiny and Inspection
- BIS officials evaluate the submitted paperwork and reports for authenticity and consistency.
- Factory inspection is done to evaluate production capacity and quality control.
- The inspector may also collect additional samples for their verification.
- Non-conformities, if any, must be corrected before final approval.
Step5:Grant of License
- BIS grants a licence after a positive outcome of the inspection and report confirmation.
- The manufacturer will be permitted to put the ISI mark on the products that have been certified.
- Continue to produce in a consistent manner and adhere to BIS marking regulations.
- Keep certification by preparing for regular surveillance audits.
Documents required for BIS Certification
| Document Name | Purpose / Description |
| Application Form (Form VI) | Official form for BIS product certification. |
| Factory Registration Proof | Confirms legal identity and manufacturing address. |
| Product Specification Sheet | Lists technical details and grade of the product. |
| BIS-recognized Lab Test Report | Verifies compliance with IS 432 Part 1:1982. |
| Manufacturing Process Flow Chart | Shows production and quality control stages. |
| Quality Control Manual | Explains internal testing and inspection procedures. |
| Equipment Calibration Certificates | Ensures accuracy of testing instruments. |
| Authorisation Letter / Power of Attorney | Allows representatives to act on behalf of applicants. |
| Undertaking of Compliance | Declaration of adherence to BIS standards. |
