Wrought aluminum and aluminum alloy rivet stock is used in a number of industries, including the aerospace, the automotive industry, the construction, and the general engineering industry. It is used due to its light weight, strength, and resistance to corrosion, which are the major advantages of wrought aluminum alloy rivet stock.
This is generally used for the manufacture of rivets, which help in the joining of different components in a proper manner, ensuring the required structural strength. In order to ensure the quality of the product, it must follow to the requirements given in the standard.
overview of indian standard is 740:1977
This standard specifies the technical requirements for the product so that it has consistent quality, proper strength, and reliable performance for fastening applications.
Key Features include:
- Chemical Composition: Ensures the correct alloy mix for strength and corrosion resistance.
- Dimensions and Tolerances: Maintains proper size and uniformity for accurate fitting
- Surface Quality: Ensures the products are free from defects
Meeting these requirements is necessary to obtain BIS Certification and ensure that the rivet stock is suitable for industrial and structural applications.
testing and inspection requirements
To ensure the quality of wrought aluminium and aluminium alloy rivet stock, IS 740:1977 defines specific testing and inspection practices during manufacturing. These checks help maintain consistency and ensure the material meets required standards.
chemical composition test
The chemical composition is checked to ensure the correct alloy is used :
- Sample: One from each cast (raw material batch)
- Testing: Can be done at approved labs (S)
If the raw material is already ISI marked and comes with a test certificate, further testing may not be required.
mechanical properties test
Tensile Test
This test checks the strength of the material.
- Sample: One from each control unit (batch)
- Conducted in-house (R) as per standard methods
freedom from defects
The material must be free from defects such as cracks or surface irregularities. Proper inspection and in-process controls are maintained during manufacturing to ensure quality.
dimensions & tolerances
The size and dimensions are checked during production to ensure proper fitting and accuracy. Adequate inspection is carried out to meet the specified requirements.
head forming test
This test checks the suitability of rivet stock for forming rivet heads.
- Sample: One from each control unit
- Applicable only for rivet stock of 1.6 mm diameter
Importance Of These Checks
These testing and inspection practices help maintain consistent quality, reduce defects, and ensure the product is suitable for industrial applications.
process for bis certification
The BIS certification process for wrought aluminium and aluminium alloy rivet stock ensures that the products meet the requirements of standard and maintain high quality and performance. The steps include:
- Online Registration: Manufacturers must register on the BIS Manak portal by providing company
details, product information, and required documents. Foreign manufacturers are
required to appoint an Authorized Indian Representative (AIR) to coordinate with
BIS.
- Testing at BIS-Approved Laboratory: Product samples are sent to a BIS-recognized laboratory for testing. Parameters
such as chemical composition, hardness, strength, and overall quality are
evaluated to ensure conformity with the standard.
- Application Submission: Applications are submitted along with test reports, technical documents, and
KYC details. Foreign manufacturers must also provide AIR information.
- Factory Inspection: BIS officials inspect the manufacturing facility to verify the production process,
raw materials, and in-house quality control systems, ensuring consistent
compliance with the standard.
- Grant of BIS License: Upon successful verification of documents, test reports, and inspection results,
BIS grants the certification license.
- Use of ISI Mark: Certified manufacturers can use the ISI mark along with the CML number on their
rivet stock, which shows that the product meets the standard and assures buyers
about its quality and safety.
