BIS ISI Certification for Wrought Aluminium and Aluminium Alloy Bars, Rods and Sections for general engineering applications IS 733:1983
Wrought aluminium and aluminium alloy bars, rods, and sections are widely used in general engineering applications due to their excellent strength-to-weight ratio, corrosion resistance, and formability. These products are manufactured through processes such as extrusion, rolling, or drawing, making them suitable for structural, fabrication, and industrial applications.
Indian Standard IS 733:1983 specifies the requirements for wrought aluminium and aluminium alloy bars, rods, and sections used for general engineering purposes. The standard covers material composition, dimensions, tolerances, mechanical properties, and quality requirements to ensure reliable performance in various industrial applications.
BIS ISI certification under IS 733:1983 is mandatory for these products, Manufacturers must obtain a BIS license to use the ISI mark before manufacturing, importing, or selling them in the Indian market. This certification ensures that the products meet prescribed quality, safety, and performance standards.
IS 733:1983 – Key Technical Requirements for Wrought Aluminium Bars, Rods and Sections
- (i) Chemical composition requirements of aluminium alloys
- (ii) Mechanical properties including tensile strength
- (iii) Dimensional accuracy, tolerances, and sectional limits
- (iv) Freedom from surface and internal defects
- (v) Peripheral coarse grain structure requirements
- (vi) Manufacturing processes such as extrusion, rolling, or drawing
- (vii) Marking, identification, and traceability requirements
- (viii) Inspection and testing procedures as per the standard
Overview of ISI Mark Certification for Wrought Aluminium and Aluminium Alloy Products
IS 733:1983 applies to wrought aluminium and aluminium alloy bars, rods, and sections intended for general engineering purposes. These products are used in construction, transportation, machinery, and various fabrication applications where strength and corrosion resistance are essential.
The standard ensures that the materials meet specified chemical, mechanical, and dimensional requirements. It also defines acceptable manufacturing practices and quality control measures to maintain consistency and reliability of the products.
BIS ISI certification under the Product Certification Scheme (Scheme I) confirms compliance with IS 733:1983. Manufacturers must establish proper manufacturing facilities, testing capabilities, and quality assurance systems before obtaining the license to use the ISI mark.
