BIS CERTIFICATION FOR STEEL WIRE IS 16644: 2018

INTRODUCTION

Steel wire is a strong and durable alloy of iron and carbon. It is used for making strings in musical instruments, electrical wiring, cables, industrial machinery and equipment. It is valued for its various properties, including strength, flexibility, and resistance to wear and tear.

To ensure the product quality of 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
