STEEL FOR VOLUTE & HELICAL SPRINGS IS 3195:1992

BIS CERTIFICATION FOR STEEL FOR VOLUTE & HELICAL SPRINGS IS 3195:1992

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 3195: 1992 for steel for the manufacture of the volute and helical springs for railway rolling stock.

This specification outlines the criteria for steel flats and rounds used in crafting volute and helical springs for railway rolling stock. Flats and rounds meeting this standard can be produced from steel ingots and billets conforming to IS 8052:1976.

The steel must adhere to one of the eight specified grades outlined in the standard. IS 8910:1978 provides the general material supply requirements. Steel production methods, excluding the Bessemer process, are permissible, provided they are followed by secondary refining or vacuum melting. To ensure quality, for each size of finished steel product, the ingots, billets, or continuous cast billets must be sized to allow for a minimum reduction ratio of 16:1 from the product's minimum cross-sectional area.

MARKING:

Marking must adhere to IS 3195:1992 standards. Each bar should bear the manufacturer's name or trademark, grade, and a cast number or identification mark enabling traceability to its origin. Additionally, the standard mark (ISI Mark) may be applied to the material.

Manufacturers must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark). The Bureau issues a license following a thorough evaluation of manufacturing infrastructure, production processes, and quality control and testing capabilities conducted during an on-site visit to the manufacturing facilities.
