- BIS certification according to IS 3502:2009 is a must for all steel chequered plates that are either sold or imported in India.
- The standard maintains the quality of the product in a uniform way, which includes the material composition, the strength, the bend test, and the 0.8 mm bead height.
- Certification by BIS includes an inspection, testing, documentation, and regular surveillance.
- Government tenders require certified plates and thus these plates enhance the trust of the market.
- License holders are obliged to undergo audits, keep up the markings, and be in step with BIS changes.
Introduction
A medium-sized steel fabricator from Raipur was on the verge of having a shipment rejected at the loss of several lakhs just because their chequered plates were not BIS certified as per IS 3502:2009. From the appearance, the plates were fine but they failed to meet the standards in testing and documentation. The cases like these are the reasons why BIS certification has become very important in the steel supply chain in India. Basically, it is an assurance that each plate is tested and found to be compliant with the strength, composition, and dimensional standards specified by the Bureau of Indian Standards.
What is IS 3502:2009?
IS 3502:2009 is the Indian Standard that defines the quality and performance requirements for steel chequered plates. It is a product of the Bureau of Indian Standards (BIS), and it lays down the mechanical, chemical, and dimensional requirements that have to be met by such plates in order to be used safely and for a long time in industrial and structural applications.
Key Points:
- It refers to hot-rolled steel chequered plates that are utilized in flooring, platforms, and stair treads.
- Determines the grade of the base material, which is most often E250A of IS 2062.
- Sets the minimum bead height of 0.8 mm for the anti-slip surface.
- Takes into account the tensile strength, the bend, and the chemical composition for testing.
- Requires the manufacturer’s name, grade, and BIS licence number to be marked. ISI MARK
Why is BIS Certification Mandatory
BIS certification is mandatory for steel chequered plates under IS 3502:2009 to ensure quality, safety, and compliance with national standards. It prevents the sale of substandard products and builds trust in the market.
Key Points:
- Ensures strength, durability, and safety of plates.
- Required under the Ministry of Steel’s Quality Control Order.
- Mandatory for manufacturing, sale, and import in India.
- Needed for government and industrial tenders.
- Protects users from faulty or unsafe materials.
Importance & Benefits of BIS Certification
| Importance | Benefits |
| Ensures compliance with IS 3502:2009 and national quality standards | Guarantees consistent product quality and performance |
| Prevents circulation of substandard or unsafe steel products | Reduces risk of rejection or safety issues in projects |
| Acts as proof of credibility for manufacturers and suppliers | Builds trust with clients and government authorities |
| Mandatory for participation in regulated and government tenders | Expands market access and business opportunities |
| Promotes standardization and traceability in production | Improves operational efficiency and quality control |
| Protects end users and industries from material failures | Strengthens brand reputation and long-term reliability |
Step-by-Step Process of BIS Certification
Step1:Documentation
- Gather all the technical documents that provide detailed explanation of the product and the production process.
- While getting the documents ready, you can also details of the factory, quality control records, and the process flow charts.
- Besides that, get test reports, raw material certificates, and quality manuals ready.
- Before your submission, check the documents once again to confirm that you are completely ready and therefore will not have to wait for the missing parts.
Step2:Product Testing
- Make product samples ready and take them to a lab that is BIS accredited for testing.
- The tests may be of the product’s chemical, mechanical, and dimensional aspects.
- Ensure that the findings comply with the corresponding Indian Standard (e.g., IS 3502: 2009).
- Do not forget to save a copy of every test result for your reference and for the time when it may be needed for inspection purposes.
Step3:Application Submission
- The BIS officials go through the quality control systems, and manufacturing capability of the applicant.
- They also check for test equipment, calibration records, and production setup.
- Samples are taken without the knowledge of the manufacturer for neutral verification.
- Track the application status until inspection is scheduled.
Step4:Scrutiny and Inspection
- BIS officials verify manufacturing capability and quality control systems.
- Inspect test equipment, calibration records, and production setup.
- Randomly select samples for independent verification.
- Address any observations raised during inspection promptly.
Step5:Grant of License
- Licence is issued after successful verification and compliance.
- The manufacturer receives permission to use the BIS Standard Mark (ISI mark).
- The license information is made available on the BIS database for verification purposes.
- Keep up with the ongoing compliance through regular inspections and renewal.
