BIS CERTIFICATION FOR METALLIC COATED STEEL STRIP & SHEET
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 15961: 2012 Hot Dip Aluminium-Zinc Alloy Metallic Coated Steel Strip and Sheet (Plain).
This standard specifies the requirements for continuously hot-dip aluminium-zinc alloy metallic coated steel strip and sheet (plain) thicknesses ranging from 0.25 mm to 1.5 mm. Sheets and coils are made by uniformly coating both surfaces of a cold-rolled steel coil. This standard specifies the following requirements for steel grades, coating classes, and surface finishes:
- Normal (N)/Skin-passed (S)
- Aluminum/Zinc coating classes
- Structural steel-grades
IS 8910 specifies the general requirements for the supply of aluminium-zinc alloy metallic coated steel strip and sheet (plain). IS 513 specifies the base metal for cold-rolled low carbon steel strip for aluminium-zinc alloy metallic coated steel strip and sheet (plain).
The cold-rolled strip is coated by immersing it in a bath of molten aluminium, zinc, and control elements at a temperature suitable for producing a complete and uniformly adhering aluminium-zinc alloy metallic coating. Coated surfaces may be subjected to treatments such as temper mill pass, surface passivation, or other coatings for a variety of reasons. The chemical composition of the base steel must meet IS 513 requirements.
The following test shall be carried out in accordance with the method specified.
- Tensile test
- Coating test
- Coating adhesion test
- Dimension, shape, and tolerances
The following information must be legibly and permanently marked on the top of each coil or package of sheets, or shown on a tag attached to each coil or packet:
- Manufacturer's name or trade-mark
- Material identification/coil number/packet number/batch number, etc
- Product dimensions
- Number of sheets or mass
- Steel grade
- Coating class
- Date of manufacture
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.
