- BIS Certification for Stainless Steel Bars and Flats IS 6603:2001 is a compulsory product standard for a regulated area in India.
- The certification is a kind of guarantee that stainless steel bars and flats are conforming to the established chemical and mechanical requirements.
- The BIS Certification for Stainless Steel Bars and Flats IS 6603:2001 scheme involves filing an application, undergoing an audit, and laboratory testing.
- The majority of the time that this certification is delayed is due to gaps in documentation and non-compliance in testing.
- BIS Certification for Stainless Steel Bars and Flats IS 6603:2001 allows manufacturers to earn the trust of OEMs and government buyers.
Introduction
We had a case of a stainless steel rolling unit in Pune that lost a railway major order after they do not have BIS Certification for Stainless Steel Bars and Flats IS 6603:2001. Their material quality was good but the buyer could not use their products due to the lack of certification. Cases like this metal companies’ manufacturers are now common. The standard has become a minimum level for anyone providing bars and flats which are used in structural, automotive, and engineering applications. Knowing what the certification requires and getting the factory ready can help you avoid production stoppages that are costly and disruptions of the supply-chain. Bureau of Indian Standards
What is IS 6603:2001?
IS 6603:2001 identifies the quality of stainless steel bars and flats as per Indian Standard. It determines the minimum chemical, mechanical and dimensional requirements that manufacturers have to conform to, before they can supply these products to the regulated sectors.
Key Points:
- It is applicable to hot-rolled and forged stainless steel bars and flats.
- It defines the limits of chemical composition for various grades of stainless steel.
- It specifies the requirements of tensile strength, hardness, and elongation.
- It also provides for the tolerances in dimensions, straightness, and surface finish.
- It is used as the standard for BIS certification and ISI marking in India.
Why is BIS Certification Mandatory
BIS certification is a must due to the fact that stainless steel bars and flats are the parts which are generally put in life-dependent or safety-critical situations. So, the devices or equipment used in these areas must have safety, performance, and traceability features and that is why it cannot be compromised. To ensure that substandard materials do not get into the market, the government has imposed the requirement for compliance with IS 6603:2001.
Key Points:
- Mandatory under BIS (Conformity Assessment) Rules for regulated products.
- Ensures the stainless steel meets chemical and mechanical requirements.
- Required by government tenders, railways, metro, defence, and major OEMs.
- Prevents circulation of unsafe or low-grade steel in the market.
- Provides legal approval for marking and selling products as per IS 6603:2001.
