BIS Certification for Hot-Rolled Carbon and Alloy Steel Plates, Sheets, and Strips under IS 19608 is important under India’s Quality Control Order (QCO). This certification ensures that the products covered by this standard have been tested and approved in accordance with the relevant Indian standard. Obtaining a BIS license (ISI mark Certification) helps manufacturers and foreign exporters to sell steel products in the Indian market legally and to gain a competitive edge. 

 

The steel grades covered by this standard are hot-rolled low-carbon, medium-carbon, high-carbon, and alloy steel plates, sheets, and strips. These steel products are rolled at high temperatures (above recrystallisation), producing durable, ductile materials for structural and general fabrication.

 

Overview of IS 19608 Indian Standard for Hot-rolled Carbon and Alloy

IS 19608 is an Indian standard that specifies the requirements for hot-rolled carbon and alloy plates, sheets and strips intended for general structure and industrial applications. These standards define the chemical composition, mechanical properties, dimensions, and testing methods that manufacturers must comply with for the safe and reliable use of applications. This standard covers a wide range of steel grades used across sectors, including construction, automotive, pipe manufacturing and heavy engineering. This compliance with IS 19608 ensures that steel products meet the safety and consistency benchmarks.

 

 Key Requirements for Carbon & Alloy Steels BIS License Approval

The key requirements for BIS certification under this scheme involve documentation, sample testing and adherence to guidelines. Some requirements are listed below:-

  • Product compliance: The product must comply with the relevant Indian Standard (IS) notified under the Quality Control Order (QCO).
  • Manufacturing ability: The manufacturing units must have the necessary facilities to ensure that products meet Indian standards.
  • Authorised Indian representative (AIR): Foreign manufacturers must appoint an AIR in India under FMCS to handle all compliance-related requirements.
  • Applied only to Manufacturer: Only the genuine manufacturers of the product can apply for a BIS Certificate, not importers or distributors. 

 

IS 19608 Testing Requirements 

To obtain a BIS license for alloy and carbon products in India under IS 19608, as mentioned in the table below:-

S. no

Test Name

Purpose

Key Parameters

1.

Chemical Composition

Test

Used to verify the chemical composition of the product

carbon, nickel, manganese, sulphur, alloy elements 

2.

Dimensional Tolerance Test

Helps in verifying the size accuracy

The thickness, width, and length of the products

3.

Marking and Identification Test

It ensures traceability

Grade manufacturer details and heat number

4.

Tensile Strength Test

It ensures the strength and durability of the hot-rolled carbon 

Tensile Strength, elongation, and yield strength.

5.

Bend Test

To check the flexibility

The branding must be done without cracks and fractures

 

All testing must be conducted at a BIS-accredited laboratory.

BIS Certification Process for IS 19608 Accessing the Indian standard for Carbon and alloy involves several important steps. Below are the key steps involved:

  • Identify the applicable standards- Confirm that the applicable standard (IS 19608) is for the hot-rolled carbon and alloy steel plates and strips product category.
  • Documentation and application filing: Create an account on the BIS portal, complete the application process, and submit the required documents, including factory details, product specifications, and test reports.
  • Product testing: Submit the samples to the BIS laboratory. All sample testing should be conducted only in laboratories accredited by BIS.
  • Audit and factory inspection:  After the application is filed, BIS auditors will review your documents and conduct the necessary inspection.
  • Grant of the BIS licence: BIS will issue a Certificate of Conformity (License) upon the successful completion of the inspection.

 

How to Choose a Consultant for ISI Mark Certification under IS 19608?

Choose the right BIS Certification Consultant. There are some steps to consider when reaching out to good consultants. 

  • The right consultant with proven product-specific experience is a must; they must possess deep knowledge of BIS schemes and a strong reputation in navigating audits and documentation.
  • Always check client reviews and case studies to check their reliability and project success.
  • Verify their in-house technical experts to ensure smooth compliance.
  • A consultant based near BIS headquarters often provides the best liaison service faster. 
  • Prioritise the consultant with end-to-end services, transparent pricing and reliable approvals.
