Wrought aluminium and aluminium alloy forging stock and forgings are materials that are useful in creating strong and durable products. These materials are created by undergoing a forging process, which enhances their durability and performance. They are mostly utilized in industries such as automotive, aeronautics, and heavy benginering , where there is a need to withstand high pressures and loads.
BIS certification of wrought aluminium and aluminium alloy products ensures that they meet to certain standards and are fit for use in various industries.
overview of indian standard is 734:1975
This standard defines the key technical requirements for wrought aluminium and aluminium alloy forging stock and forgings. It ensures that the products have the required strength, quality, and performance for industrial applications.
Key Features include:
- Chemical Composition: Ensures the correct alloy mix for strength and durability
- Dimensions and Tolerances: Maintains proper size and accuracy for use
Meeting these requirements is essential to obtain ISI Certification and ensure reliable product performance.
testing and inspection requirements
To ensure the quality of wrought aluminium and aluminium alloy products, the standard defines specific inspection and testing practices during manufacturing. These checks help maintain consistency and ensure that the material meets the required specifications.
freedom from defects
The material must be free from defects such as cracks, surface irregularities, or imperfections. Manufacturers are required to maintain proper inspection and in-process controls to ensure consistent quality throughout production.
chemical composition check
The chemical composition is verified to ensure the correct alloy is used. One sample is tested from each cast (raw material batch) using standard testing methods. This test must be conducted within the factory (R).
mechanical properties test
Mechanical properties such as strength and toughness are tested to ensure performance under load. One sample is taken from each production batch (control unit)and tested in-house (R) as per standard methods.
dimension and tolerances
The product must meet the required tolerances and dimensional specifications. Adequate inspection is carried out during production to ensure that the material conforms to the agreed requirements between the manufacturer and the purchaser.
Importance of These Checks
These testing and inspection practices help maintain consistent product quality, ensure compliance with standards, reduce defects, and ensure reliable performance in industrial applications.
Process for BIS Certification

The BIS certification process is designed to ensure that wrought aluminium and aluminium forging stock and forgings possess the quality and performance characteristics specified under the standard. The certification process is simple and consists of the following steps:
- Online Registration: The first step in getting BIS certification is to register on the Manak portal, BIS’s
online platform. Manufacturers need to create an account, fill in company details,
and provide information about the product and manufacturing process. They also
have to upload supporting documents like technical specifications and test
reports. For foreign manufacturers, a hard copy of the application and documents
must be sent to the BIS office, and an Authorized Indian Representative (AIR)
should be appointed to handle communications.
- Testing at BIS-Approved Laboratory: Product samples are tested in a BIS-recognized laboratory to check compliance
with requirements like composition, strength, and dimensions as per IS 734:
1975.
- Application Submission: The application is submitted along with test reports, technical documents, and
KYC details. Foreign manufacturers must also appoint an Authorized Indian
Representative (AIR).
- Factory Inspection: BIS officials inspect the manufacturing unit to verify:
- Forging process and production methods
- Quality of raw materials and alloy composition
- Manufacturing facilities and infrastructure
- In-house testing and quality control systems
- Grant of BIS License: After successful verification of documents, test results, and inspection, BIS
grants the license.
- Use of ISI Mark: Once certified, the manufacturer can use the ISI mark along with the CML
number on the product or packaging to show compliance with IS 734: 1975.
