Wrought aluminium and aluminium alloy sheets and strips, are flat, thin products made from aluminium and its alloys, designed to offer strength, durability, and ease of use in various applications.These are extensively used in various industries such as construction, transportation, aerospace, and general engineering, due to their light weight, high strength, and resistance to corrosion. They are best suited for applications where performance and service life are critical..
BIS certification for this aluminium sheets and strips ensures that they comply with standards in terms of composition, strength, dimensions, and finish, thus ensuring their reliability for use in various industries.
overview of indian standard is 737:2024
This standard specifies the technical requirements for the product aluminium sheets and strips to ensure proper quality, strength, and performance for industrial use.
Key Features include:
- Chemical Composition: Ensures correct alloy mix for strength and corrosion resistance
- Dimensions and Tolerances: Maintains proper thickness and size for accurate use
Meeting these requirements is essential to obtain ISI Certification and ensure reliable product performance.
testing and inspection requirements
To ensure the quality of aluminium products, the standard defines specific inspection and testing practices during manufacturing. These checks help maintain consistency and ensure the material meets required specifications.
freedom from defects
The material must be free from harmful defects such as cracks or surface imperfections. Proper in-process controls are maintained during manufacturing to ensure consistent quality.
chemical composition test
The chemical composition is checked to ensure the correct alloy is used.
- Sample: One from each heat (raw material batch)
mechanical properties test
Tensile Test
This test checks the strength and durability of the wires.
- Sample: One from each control unit (batch)
Bend Test
This test checks the flexibility of the material.
- Sample: One from each control unit
- Applicable for material up to 2.6 mm thickness
condition (temper) check
The material must be supplied in the required temper condition as specified by the purchaser. Proper in-process controls ensure compliance with this requirement.
Importance of These Checks
These testing and inspection practices help maintain consistent quality, reduce defects, and ensure that the material meets standard requirements for reliable use.
Process for BIS Certification
The BIS certification process ensures that product meet the quality and performance requirements specified under standard. The process includes 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 lab to check compliance with
requirements such as composition, strength, thickness, and surface finish.
- Application Submission: The manufacturer submits the application 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:
- Manufacturing process
- Quality of raw materials
- Factory setup and infrastructure
- In-house testing and quality control
- Grant of BIS License: After verification of documents, test results, and factory 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 737: 2008.
