BIS CERTIFICATION FOR STRUCTURAL STEEL
In this competitive scenario, it isn't easy to survive in the market without a standard quality and certified product. BIS license may also be required to sell products in the Indian market.
To get BIS certification and produce a standard quality product, the manufacturer must ensure that their product must follow the specified Indian standard.
Let's take a closer look at IS 3039:1988 for Structural steel for the construction of hulls of ships.
This standard specifies the requirements for rolled structural steel plates, sections, flats, and bars used in the construction of ship hulls. Grade I is intended for general use, whereas Grade II and Grade III are intended for special uses. This standard does not apply to rivet bars used in ship construction.
The steel shall be produced using an open hearth, an electric furnace, basic oxygen, or any other process approved by the purchaser. The nitrogen content of steel produced by the basic oxygen process shall not exceed 0.007 percent. Grade I steel can be killed or semi-killed. Grade II steel shall be of the killed type, manufactured with fine grain practice and the use of aluminium or other grain refiners. Grade II steel can also be supplied semi-killed in thicknesses up to and including 35 mm if the steel over 25 mm thickness is normalized. Grade III steel shall be supplied in fully killed conditions, manufactured with fine grain practice, and the use of aluminium and other grain refining elements such as Nb, V, and Ti.
All materials must be free of cracks, surface flaws, segregation, lamination, pipe, and other defects which will be harmful to the service of the material. Surface defects may be removed by chipping or grinding so that the material thickness does not fall below 93 percent of the nominal thickness, but no more than 3 mm at the dressed location.
The following test shall be carried out in accordance with the standard.
- Tensile test
- Impact test
- Chemical composition
Every finished product must be marked with the inspecting authority's brand in at least one location by the manufacturer. Unless otherwise agreed, the following information must also be marked on each product:
- Manufacturer’s name or trade-mark
- Grade of steel
- Cast number
- Purchaser’s identification mark, if required by the purchaser.
The standard mark (ISI Mark) may also be applied to the material. Manufacturers 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.
