INTRODUCTION

Steel for hardening and tempering is a special type of steel. It goes through two heating steps. First, it's heated to become harder and stronger. Then, it's heated again to make it less likely to break and more resilient. This kind of steel is used for making things like tools and blades, where you need them to be both hard and tough.

To ensure the product quality of steel for hardening & tempering, 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 8910:1978 specifies the general requirements for material supply.

This standard specifies the technical and delivery requirements for wrought alloyed and unalloyed steels in the form of bars, rods, flats, plates, forgings, etc to be used in hardened and tempered conditions. This standard's steel is generally intended for forging and machining of parts for engineering or automobile purposes.

REQUIREMENTS FOR IS 5517:1993

1.     Steels covered by this standard must be ordered and delivered on any of the basis specified in table 1 of the standard.

2.     Unless otherwise agreed to in the order, the processes used in the manufacture of the steel and the product shall be left to the manufacturer's discretion, but the steel shall be fully killed.

3.     As determined by macro etching and ultrasonic testing, sufficient reduction and discard must be made to ensure freedom from piping, harmful segregation, and so on.

4.     The material must be free of surface and material defects that could impair its end-use.

5.     All bars of 50 mm Dia or equivalent section and above must be stamped or suitably marked at the end with the heat number and the manufacturer's name or trade mark.

6.     Bars in smaller sections will be tied to appropriate bundles with metal tags containing the information.

7.     The Standard Mark (ISI Mark) may also be applied to the material.

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

• ISI Mark Certification for Foreign Manufactures

Under BIS Registration Products ISI and CRS

• BIS CRS Registration For IT Products List
• ISI Mark Registration For ISI Products List

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

Steel for hardening and tempering has been included in the mandatory ISI Certification Scheme under the IS 5517: 1993 standard. Manufacturers cannot import, export, or sell this product in the Indian consumer market without the ISI Mark imprinted.
