INTRODUCTION

Stainless steel wire is a strong and long-lasting type of wire made from a special kind of steel called stainless steel. This steel doesn't easily rust or wear out, making it perfect for many different uses. It comes in different types for different jobs, like building things, making things for planes and ships, car parts, medical equipment, jewelry, and more.

To ensure the product quality of stainless steel wire, the Bureau of Indian Standards (BIS) has made it mandatory for manufacturers to undergo BIS registration and obtain the BIS ISI mark before selling it in the market. Manufacturers can use the ISI Mark on their products only after obtaining a license from BIS that is granted after BIS registration. The presence of the ISI mark on a product indicates that it complies with BIS's stringent quality standards.

IS 4454 (PART 4): 2001 covers 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.

REQUIREMENTS FOR IS 4454 (part 4): 2001

1.     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.

2.     The stainless-steel wire shall be classified into three grades: grade 1, grade 2, and grade 3.

3.     The general requirements for material supply are specified in the applicable standard.

4.     The processes used in manufacturing steel and stainless spring steel wire are left to the manufacturer's discretion.

5.     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.

6.     The tolerance on wire diameter shall be as specified in the standard.

7.     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.

8.     The wire can be coated or uncoated, and mechanical properties must meet standard requirements.

9.     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.

10.  The standard mark (ISI Mark) may also be applied to the material.

11.  The Manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark).

TESTS

·       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

Benefits of BIS Certification

The BIS registration provides the following benefits:

1.     Increase sales: BIS-registered products are more likely to be of higher quality and attract more customers.

2.     Reduce the amount of money spent on quality maintenance: Upon getting certification, there's no need to follow separate quality guidelines for products.

3.     Enhance product credibility and reduce environmental risk: BIS-certified items are genuine and trustworthy because they work really well and last a long time.

4.     Ensure the highest level of quality and dependability: The presence of a BIS registration number implies that the product is of high quality and dependability.

5.     Ensure the organization’s expansion: BIS certification boosts your product’s reputation, resulting in significant growth and market exposure.

CONCLUSION

Stainless steel wire has been included in the mandatory ISI Certification Scheme under the IS 4454 (PART 4): 2001 standard. Manufacturers cannot import, export, or sell this product in the Indian consumer market without the ISI Mark imprinted.
