Professional BIS/ISI mark certification consultancy for structural steel rolling mills, plate manufacturers, and section producers. Comprehensive guidance on the restructured IS 2062 (Part 1):2025 and (Part 2):2026 standards, Scheme of Inspection and Testing (SIT) quality records, and mandatory Ministry of Steel QCO compliance.
The Bureau of Indian Standards has restructured the legacy IS 2062:2011 specification into two dedicated parts, establishing clear technical frameworks for hot-rolled structural shapes and quenched & tempered steel products.
Compliance must reflect the newly notified two-part architecture governing structural steel manufacturing across Indian mills.
Grades are designated by the letter "E" followed by the minimum specified yield strength in Megapascals (MPa).
Sub-qualities specify Charpy V-notch impact energy verification across temperature ranges to ensure brittle-fracture resistance.
Certification applies across diverse product geometries produced by rolling mills and heavy section fabricators.
Adhering to the BIS Scheme of Inspection and Testing (SIT) requires systematic verification of chemical heats, tensile strength, and impact energy. Mills have practical options for establishing testing compliance.
Structural steel testing involves heavy-capacity Universal Testing Machines (UTM) for tensile and bend evaluations, alongside Charpy impact testing apparatus for sub-qualities BR, B0, and C. Instruments must hold valid calibration records.
In accordance with modern BIS policy directives, mills need not assume that complete in-house facilities are universally compulsory for every single parameter. Where permitted, mills can utilize approved shared cluster facilities or recognized external laboratories.
Ladle analysis must confirm maximum limits for Carbon, Manganese, Sulphur, and Phosphorus, alongside Carbon Equivalent (CE) calculation to guarantee field weldability without preheat cracking.
From initial rolling mill review to official license grant, Sun Associates guides steel manufacturers through each regulatory stage.
Evaluating rolling mill capacity, section sizes, and raw material inputs
We review your mill pass schedules, reheating furnace controls, raw material billet/slab sources, and dimensional inspection tools against IS 2062 (Part 1):2025 and (Part 2):2026 requirements, establishing a clear compliance roadmap.
Structuring inspection formats and online application submission
Our consultants draft custom quality manuals, daily SIT test formats, and chemical heat control logs. The application is compiled and filed on the official BIS Manakonline portal with all necessary technical enclosures.
Pre-audit verification with mill quality teams
Before the BIS inspecting officers visit your mill, our team conducts on-site pre-audit checks. We assist your laboratory personnel in rehearsing tensile, bend, and impact tests, ensuring full confidence during the official factory audit.
Independent testing clearance and formal license issuance
During the audit, officers draw and seal representative structural steel samples. These are dispatched to a BIS-recognized laboratory for comprehensive testing. Upon clearance of the test report, BIS issues your official CML license number.
Located in Central India's industrial corridor, Sun Associates brings practical familiarity with heavy section rolling, plate rolling, and secondary steel production realities.
We understand rolling mill operations across Chhattisgarh and Maharashtra, providing pragmatic solutions for roll-pass tolerances, Carbon Equivalent control, and heat-wise batch segregation.
Through our affiliated Sunrise Testing & Calibration Centre network, we coordinate the periodic calibration of testing instruments, UTMs, and dimensional gauges required for audit compliance.
Our support continues after certification, assisting with annual marking fee returns, scope inclusion for new section sizes, and unannounced BIS surveillance inspections.
Regulatory Scope Clarification: Sun Associates is a management systems and compliance consultancy division. We provide technical advisory, process gap evaluation, documentation preparation, and audit readiness support. Bureau of Indian Standards (BIS) is the statutory authority that inspects premises, evaluates product samples, and issues licenses.
Common questions from rolling mill owners, plant heads, and quality managers regarding IS 2062 licensing.
The Bureau of Indian Standards restructured the legacy single-volume IS 2062:2011 into two dedicated parts: IS 2062 (Part 1):2025 for hot rolled medium and high tensile structural steel (covering plates, sections, channels, angles, and beams) and IS 2062 (Part 2):2026 for quenched and tempered steel plates, sheets, strips, and wide flats.
Sub-qualities define Charpy V-notch impact toughness requirements. Quality A designates general engineering steel where impact testing is not mandatory. Quality BR requires impact energy verification at room temperature (+27°C). Quality B0 requires verification at sub-zero 0°C, and Quality C requires low-temperature impact testing down to -20°C or -40°C depending on grade specification.
Yes. The Ministry of Steel enforces compulsory BIS certification under the Steel and Steel Products (Quality Control) Order. Producing, stocking, or distributing structural steel without a valid BIS license and ISI mark is prohibited by law across India.
Mills must ensure that quality verification required by the Scheme of Inspection and Testing (SIT) is systematically performed. Under updated BIS directives, manufacturers can maintain in-house mechanical and chemical apparatus or leverage approved shared cluster facilities and recognized external testing laboratories for selected parameters, subject to applicable guidelines and BIS approval.
No. BIS Scheme-I licenses are granted strictly to manufacturing units that possess production machinery and quality control systems. Stockists and fabricators must ensure their material is sourced directly from BIS-licensed manufacturing mills.
