Wrought aluminum alloy bolt and screw stock refers to metal rods or wires made from
aluminum alloys that are used to manufacture bolts, screws, and other fasteners. These
materials are widely used in general engineering because they are lightweight, easy to
shape, and suitable for different industrial applications like machinery, construction, and
fabrication work.
Since these materials are used to make important fastening components, their quality
needs to be properly controlled. BIS certification under IS 1284:1975 helps ensure that
the aluminum alloy stock meets the required standards for composition, strength, and
usability before being sold in the market.
why is bis certification necessary for wrought aluminium alloy bolt and screw stock for general engineering purposes
BIS certification under IS 1284:1975 is required for businesses involved in
manufacturing, importing, or supplying this material in India.
Applicable to:
- Manufacturers – Producing aluminium alloy bolt and screw stock in India
- Importers – Bringing stock from other countries into India
- Suppliers / Brand Owners – Supplying or selling the material under their own
brand name in the Indian market
Testing and Inspection Requirements for Aluminium Alloy Fasteners
To ensure proper quality and performance of these fasteners, IS 1284:1975 specifies
testing and inspection requirements. These tests are carried out during manufacturing
and quality checks.
What are R and S?
- R (Required): Test must be conducted in the manufacturer’s in-house laboratory
- S (Subcontracting Allowed): Test can be conducted in a BIS-approved or
NABL-accredited laboratory
Material & Chemical Tests
- Chemical Composition Test (S)—Checks aluminum alloy composition as per
standard limits
- Alloy Verification Test (S) – Confirms correct grade of material
Mechanical Performance Tests
- Tensile Strength Test (R) – Measures the strength of the material under load
- Elongation Test (R) – Checks how much the material can stretch before
breaking
Physical & Dimensional Tests
- Dimension Check (R) – Verifies diameter, length, and size of stock
- Tolerance Verification (R) – Ensures measurements are within allowed limits
Manufacturing & Process Checks
- Workmanship Inspection (R) – Ensures proper forming and processing of
material
- Surface Quality Check (R) – Checks for cracks, defects, or irregularities
Finish & Surface Tests
- Surface Finish Test (R) – Ensures smooth and uniform finish
- Corrosion Resistance Check (S) – Verifies resistance to environmental effects
What is IS 1284:1975?
This is an Indian Standard issued by the Bureau of Indian Standards that defines the
requirements for wrought aluminum alloy bolt and screw stock used in general
engineering. It provides guidelines on how this material should be produced and
supplied in India.
This standard ensures that the material:
- Has the correct chemical composition of aluminium alloy
- Meets required strength and mechanical properties
- Is suitable for making bolts, screws, and fasteners
- Follows proper quality requirements for engineering use
process for bis certification
The BIS
certification process for Wrought Aluminium Alloy Bolt and Screw Stock for
General Engineering Purpose involves multiple steps, designed to thoroughly
evaluate a product's compliance with the required standards. Here is a general
overview of the certification process:
- Application Submission: Manufacturers
must submit an application form along with required documentation to BIS.
- Documentation Review: BIS reviews the
submitted documents to ensure completeness and correctness.
- Factory Inspection: BIS officials
conduct an on-site inspection of the manufacturing facility to assess the
production process and quality control measures.
- Sample Testing: Product samples are
taken and tested in BIS-approved laboratories to verify compliance with Indian
standards.
- Certification Grant: Upon successful
completion of the inspection and testing, BIS grants certification, allowing
the manufacturer to use the BIS mark on their products.
