IS 2419:1982 is the Indian Standard (BIS) for wrought aluminium and aluminium alloy solid extruded sections for architectural purposes - specification. This standard specifies the requirements for solid extruded sections of wrought aluminium and aluminium alloys intended primarily for architectural applications such as doors, windows, curtain walls, and interior fit-outs. It covers chemical composition, mechanical properties, and testing protocols.
Specifies the requirements for solid extruded sections of wrought aluminium and its alloys used in architectural applications.

Practical Notes
! Alloy designation 63400 (old HE9) in WP temper is the most commonly specified material for architectural profiles due to its optimal balance of strength, surface finish, and corrosion resistance.
! If the sections are intended to be anodized, 'anodizing quality' must be explicitly specified at the time of inquiry or order to ensure appropriate surface finish controls.
! This code specifically deals with solid sections. For hollow extruded architectural sections, refer to complementary standards like IS 3965.
Standard Specification for Aluminum and Aluminum-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes
Covers general requirements for aluminum extruded profiles, including alloys common in architecture like 6063 and 6061.

Aluminium and aluminium alloys - Extruded rod/bar, tube and profiles (Parts 1: Technical conditions, 2: Mechanical properties, 9: Profiles, tolerances)
Direct European equivalent specifying technical conditions, mechanical properties, and dimensional tolerances for general extruded profiles.

HighCurrent
Aluminium and aluminium alloys - Extruded precision profiles in alloys EN AW-6060 and EN AW-6063 (Parts 1: Technical conditions, 2: Tolerances)
Specifically covers high-tolerance extruded profiles in alloys 6060/6063, which are primary architectural alloys.

MediumCurrent
Wrought aluminium and aluminium alloys — Extruded rods/bars, tubes and profiles (Parts 1: Technical conditions, 2: Mechanical properties, 5: Tolerances)
Provides an international framework for extruded profiles, but specific national/regional standards (EN, ASTM) are more commonly cited.
Key Differences
≠IS 2419 has been officially withdrawn and superseded by IS 6477 (which is also withdrawn), with current practices often referring to IS 733:1983 or international standards. Modern equivalents like EN 755 and ASTM B221 are current and regularly updated.
≠Alloy designations differ. IS 2419 uses a five-digit system (e.g., 64430 for 6063), while modern international standards use the four-digit Aluminum Association (AA) system (e.g., 6063, 6061).
≠International standards like EN 755 and EN 12020 are multi-part documents, separating mechanical properties, tolerances, and inspection conditions into different parts. IS 2419 is a single, more concise document covering all aspects.
≠Dimensional tolerances in modern standards, particularly EN 12020 for precision profiles, are significantly tighter and more detailed than the general tolerances provided in the older IS 2419:1982.
Key Similarities
≈The primary alloys specified for architectural use are fundamentally the same, with IS 64430 being the direct equivalent of the internationally ubiquitous Alloy 6063, known for its extrudability and surface finish.
≈All standards specify the same core set of requirements for product acceptance: chemical composition, mechanical properties (tensile strength, proof stress, elongation), and dimensional tolerances.
≈The concept of heat treatment to achieve desired strength is common across all standards. The 'WP' (solution treated and precipitation treated) temper in IS 2419 is analogous to the T5 and T6 tempers in ASTM and EN standards.
≈The intended application is identical: to provide specifications for solid extruded sections used in architectural applications such as window/door frames, curtain walling, and facades.
