BIS CERTIFICATION FOR STEEL FOR LAMINATED SPRINGS IS 3885 PART 2:1992

In today's competitive landscape, maintaining market presence without a certified, high-quality product can be challenging. Obtaining a BIS license may also be essential for selling products in the Indian market. To achieve BIS certification and ensure product quality, manufacturers must adhere to the specified Indian standards.

Let's delve deeper into at IS 3885 Part 2:1992 for Steel rib and groove for the manufacture of laminated springs for railway rolling stock.

This specification outlines the criteria for hot rolled steel rib and groove sections used in manufacturing laminated springs for railway rolling stock.

The steel must conform to one of the seven specified grades outlined in the standard. IS 8910:1978 outlines the general requirements for material supply. Production of the steel must utilize any steelmaking process except the Bessemer process, and it must be followed by either secondary refining or secondary vacuum melting.

For each specific size of the finished steel product, the size of the ingot, billet, or continuous cast billet must ensure a minimum reduction ratio of 16:1 from the minimum cross-sectional area to the maximum cross-sectional area of the product. However, alternative reduction ratios may be established through mutual agreement between the purchaser and the manufacturer.

The hot-rolled material should be devoid of detrimental defects like seams, folds, laps, cracks, deep pits, grooves, excessive scaling, and other issues that could lead to cracking during hardening or affect its functionality. The surface should exhibit a reasonably smooth texture without any distortion, twists, or kinks.

TESTS

The subsequent test must be conducted for Laminated Springs for Railway Rolling Stock.

MARKING:

Marking and packaging procedures must align with Indian standards. Every flat should bear the manufacturer's name or trademark, grade, and a cast number or any other identification mark enabling traceability to its origin. Additionally, the standard mark (ISI Mark) may be applied to the material.

Manufacturers are required to acquire a BIS license from the Bureau of Indian Standards in order to utilize the standard mark (ISI Mark). The Bureau issues licenses following a thorough evaluation of manufacturing infrastructure, production processes, and quality control and testing capabilities conducted during an on-site visit to the manufacturing premises.

PROCESS FOR BIS ISI MARK CERTIFICATION

BIS CERTIFICATION PROCESS

Acquiring a BIS license requires a comprehensive review of manufacturing infrastructure, quality control abilities, testing resources, and production procedures. This thorough assessment guarantees that products not only adhere to regulations but also prioritize consumer safety and reliability.
