BIS CERTIFICATION FOR STOCK FOR FORGINGS IS 13352:1992 

INTRODUCTION

Forging stock is the raw material used in forging. This stock, like bars or billets, is heated and shaped under pressure to make the desired forged item. The steels mentioned in this standard are usually meant to be used as raw materials by the forging industry for making things like car parts or engineering components.

To ensure the product quality of stock for forgings, 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

This standard specifies the technical and delivery conditions for plain carbon and low alloy grade steels in the form of bars, billets, and other shapes produced through a continuous cast route, either by rolling or forging.

The general requirements for material supply shall be by IS 1387: 1967.

4.Stock rolled/forged continuously cast steel must also be free of harmful internal defects such as corner cracks, half-way cracks, centre looseness, concentrated pinholes, voids, flakes, and so on.

5.The hardness and mechanical properties for respective grades will be as per the relevant Indian standard for which the steel is intended. Hardness and mechanical tests must be performed to ensure product quality.

6. The chemical composition, mechanical properties, and grain size must all meet the standard's requirements.

7.The foreign stock rolled from the continuously cast product must meet a high standard of surface quality, and size tolerances must be in accordance with 3739:1987.

8.Marking shall be done in accordance with IS 13352:1992. The material may also be marked with the standard mark (ISI Mark).

9.The standard mark (ISI mark) must be applied to the material. The manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark)

Conclusion

Stock for forgings has been included in the mandatory ISI Certification Scheme under the IS 13352: 1992 standard. This product cannot be exported, imported, or sold in the Indian consumer market without the ISI Mark imprinted.
