BIS CERTIFICATION FOR STRUCTURAL STEELS
IS 15962:2012

This standard specifies the requirements for steel plates, shapes and sections (angles, tees, beams, channels, and so on), flats, and bars for use in structural work for increased seismic resistance. These steels can be used in welded, bolted, and riveted structures. IS 8910 specifies the general requirements for the supply of structural steel.

The processes used in steel production and subsequent hot rolling into steel plates, sections, flats, bars, and so on are left to the manufacturer's discretion. All finished steel must be well and cleanly rolled to the specified dimensions, sections, and masses. Surface flaws, laminations, rough/jagged and imperfect edges, and all other harmful defects must be reasonably absent from the finished material. The chemical composition must adhere to specified standards.

TESTS

The following test shall be carried out in accordance with the method specified.

• Tensile test
• Impact test
• Other tests
• Dimension & Tolerance

Marking:

Except for round, square, and hexagonal bars and flats, each product must have a tag or be marked with the manufacturer's name or trademark. Bars and flats must be labelled with the manufacturer's name or trademark. Steel designation should be similarly marked on the product or tag. The cast number must be stamped on every heavy, medium structural mill, and plate mill product. Plates made from a coil-formed strip must be marked with a cast/heat number on the top plate of each pile/packet. The Standard Mark (ISI Mark) may also be applied to the material. The Manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark). The Bureau grants a license based on a successful assessment of manufacturing infrastructure, production process, and quality control and testing capabilities during a visit to its manufacturing premises.
