- Mandatory ISI Mark Requirement: BIS Certification under IS 13352:1992 is mandatory for manufacturing and sale of stock for forgings in Indian States.
- Guaranteed Quality & Forgeability: This certification ensures the chemical content and the inherent soundness of the metal regarding its forgeability.
- Less Risk of Forging Defects: Risks of cracks, rejections, and failure in the process of forging are reduced to a significant extent in BIS
- Standardized Manufacturing Quality: It enables providing uniform dimension, material, or quality, with batch-wise quality control.
- Enhanced Market Trust & Compliance: Certification by BIS increases brand trust, compliance, and consumer trust in counterfeit goods.
Introduction
Stock alloy for forgings is very essential in manufacturing components that require a high level of strength, toughness, and resistance to mechanical forces. Such components include automotive parts, machinery parts, tools, shafts, and structural machinery components that need to resist severe operating conditions due to forgings.
IS 13352:1992 ensures that the forging stock complies with the required qualities specified by the Bureau of Indian Standards (BIS), thereby ensuring that the forging stock is consistent, safe, and reliable throughout the forging process.
What Is Stock for Forgings IS 13352:1992?
IS: 13352:1992 is a standard applicable in India that prescribes requirements for the selection of steel stock meant to be forged. The standard defines the following requirements:
- Chemical Composition – Assures good forgeability & mechanical properties
- Mechanical Properties – Tensile Strength, Yield Strength, & Elongation
- Soundness and internal quality: The absence of harmful defects
- Dimensional accuracy – Standardized size, shape, and tolerances
- Surface condition – Lack of surface imperfections or seams or surface defects
- Methods of testing and inspection – It ensures quality of production.
By adhering to IS 13352:1992, the forging material will retain integrity, strength, and workability during the forging operation.
ISI Mark Certification for Stock for Forgings
To make steel stock for forgings, it should meet IS 13352: 1992 norms as per the ISI mark certification scheme. For a steel stock, it is important to know that:BIS Certification.
- Uniform mechanical and metallurgical properties
- Good forgeability without cracking or failure
- Dimensional accuracy appropriate for forging.
- Efficient batch-wise quality control
The ISI mark is allowed to be applied only after getting a legal BIS license by the manufacturer, which confirms that the manufacturer meets the regulatory standards.
Why Is BIS Certification Mandatory for Stock for Forgings?
Use of uncertified forging materials may cause serious problems, including:
- Cracks or failures during forging
- Inadequate mechanical properties in forged parts
- Higher Rejection Rates and Production Shortages
- Higher costs of maintenance and replacement
BIS certification provides assurance of:
- IS 13352: 1992
- Forgeability, ability to resist forging stresses, deformation
- Consistent quality from reliable material.
- Greater Market Acceptance and Customer Confidence
Importance and Benefits of BIS Certification
| Importance | Benefits |
| Compliance with IS 13352:1992 | Ensures reliable forgeability and strength |
| Standardized production | Guarantees uniform quality across batches |
| Mechanical reliability | Reduces failure during forging operations |
| Regulatory compliance | Avoids legal issues and market rejection |
| Brand credibility | Enhances trust among buyers and industries |
Step-by-Step BIS Certification Process
Step 1: Documentation
Prepare company details for registration, information regarding manufacturing unit, and technical details for forging stock as per BIS guidelines.
Step 2: Product Testing
Stock samples for forgings are tested for chemical content, mechanical properties, and soundness at BISrecognized labs.
Step 3: Application Submission
The application should be sent with the test results on the online portal provided by BIS.
Step 4: Scrutiny & Factory Inspection
BIS officials conduct an inspection at the site to check the manufacturing procedures, quality control, and testing facilities.
Step 5: Grant of Licence
On successful inspection and evaluation, the BIS issues the license to the manufacturers to mark their certified forging stock with the ISI mark.
Documents Required for BIS Certification
- Registration Certificate
- Details of the unit for the
- Tech specification of stock for forgings
- BIS-approved labs and test reports
- Brand Authorization (if applicable)
Timeline, Validity & Renewal
- Certification Timeline: 20-30 working days
- Licence Validity: 1–2 years
- Renewal: Supplying new documentation & compliance with ongoing licensing requirements prior to the expiry date for the license
Conclusion
BIS Certificate for Stock for Forgings IS 13352:1992 is a hallmark of quality, safety, and reliability in the industrial world. A BIS-approved stock for the forging process guarantees required mechanical properties, forgeability, and freedom from defects in the finished article.
Compliance with IS 13352:1992 is not only a legal requirement but also an informed decision that helps in improving product qualities, efficiency, and, in turn, consumer confidence. Using BIS-certified stock for forgings not only signifies reliability, efficiency, and excellence but also ensures the same in terms of quality.
