- BIS Certification under IS 15962:2012 confirms steel is suitable for seismic-resistant building structures.
- The standard guarantees that the material has controlled chemistry, ductility, and yield-to-tensile ratios within the safety range.
- This certification is being mandated for large-scale and tall-building type of projects.
- The procedure is all about sampling, audit, records verification, and visits at irregular intervals.
- Certified manufacturers gain better market access, fewer rejections, and stronger credibility.
Introduction
A few months ago, a steel supplier in Pune called me after losing a hospital project simply because his material didn’t carry the BIS Certification for Structural Steel for Building Structures with Improved seismic Resistance under IS 15962:2012. Everything else about his product was acceptable, yet the absence of this specific compliance stopped the entire order. That situation is becoming common as builders, insurers, and consultants prioritise verified seismic-resistant materials over generic grades. India’s high-rise and infrastructure projects now expect structural steel that can withstand real seismic stress, not just pass routine strength tests. This certification has become the line between acceptable supply and automatic rejection. Bureau of Indian Standards
What is IS 15962:2012?
IS 15962:2012 specifies in detail the respiratory, mechanical, and chemical characteristics as well as the performance of steel for use in structures resistant to earthquakes. The prescription highlights the necessity for the material to be capable of energy absorption, safe deformation, and maintaining its integrity when subjected to loading arising from an earthquake.
Key Points:
- Detail the parameters of ductility and yield–tensile ratio that affect the performance of the structure during an earthquake.
- Outline the limitations of chemical compositions and carbon equivalents to ensure good weldability.
- Describe minimum physical requirements like tensile strength, elongation, and impact toughness to be met.
- Provide for identification from the records of the heat number and good marking. ISI MARK
- Is steel conforming to this specification a first choice for construction of buildings in which a disaster can endanger life, such as hospitals, schools, high-rises, and public infrastructures
Why is BIS Certification Mandatory
BIS Certification is necessary to demonstrate that the structural steel utilized in buildings affected by earthquakes complies with the very strict safety and quality requirements of IS 15962:2012. It is a tool to protect the projects against failures of the materials, meet the requirements of the regulations and tenders and give the confidence to engineers, insurers, and developers.
Key Points:
- It verifies that the steel complies with the seismic performance requirements tested by BIS.
- Steel suppliers to the government and large private projects must have it.
- Stops unsafe or non-standard materials from being delivered to construction sites.
- Offers legal conformity and lessens project liabilities.
- Makes it easier for the trust to be shared between the builders, consultants, and insurers.
