BIS CERTIFICATION FOR STAINLESS STEEL WIRE
IS 4454 (PART 4):2001
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 4454 (Part 4):2001 for stainless steel wire.
This standard (Part 4) applies to stainless steels listed in the standard that is typically used in the cold drawn condition in the form of a wire with a circular cross-section up to 10 mm in diameter for the manufacture of springs and spring parts that are subjected to corrosive effects and, on occasion, slightly elevated temperatures.
Stainless steels covered by this standard and exhibiting special corrosion resistance are austenitic in nature, with chromium contents greater than 12%, and are spring hard cold drawn.
The stainless-steel wire shall be classified into three grades: grade 1, grade 2, and grade 3.
The general requirements for material supply are specified in the applicable standard. The processes used in manufacturing steel and stainless spring steel wire are left to the manufacturer's discretion. The surface of the wire must be smooth and free of defects such as grooves, pits, die-marks, and other harmful defects that have a noticeable adverse effect on the wire's application.
The tolerance on wire diameter shall be as specified in the standard. The difference in maximum and minimum wire diameters at the same cross-section shall not exceed 50% of the total permissible deviation specified in the standard. The wire can be coated or uncoated, and mechanical properties must meet standard requirements.
The following tests shall be carried out in accordance with the standard.
- Tensile test
- Wrapping test
- Reverse torsion test
- Cast of the wire
- Bend test
- Coiling test
Packaging and marking:
The material must be packed so that it is adequately protected against mechanical damage and contamination during transit. Each coil of wire and bundle of straightened and cut lengths must be legibly marked with the name of the supplier, the wire grade, the wire diameter, the surface finish, the mass of the coil, the cast or batch number, and the date of supply. The standard 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. 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.
