BIS Certification Consultancy for Wrought Aluminium and Aluminium Alloy Plates | IS 736
Wrought aluminium and aluminium alloy plates are widely used in general engineering, industrial equipment, fabrication, transportation, machinery and infrastructure applications. These products require consistent chemical composition, mechanical properties, dimensions and surface quality to ensure reliable performance in their intended applications.
In India, the Bureau of Indian Standards (BIS) operates product certification schemes to verify conformity with applicable Indian Standards. Manufacturers and importers dealing in wrought aluminium and aluminium alloy plates should understand the relevant standard, the applicable Quality Control Order (QCO), product testing requirements and the process for obtaining a BIS licence.
Important October 2026 update: BIS has established a revised edition,
IS 736:2026 — Wrought Aluminium and Aluminium Alloy Plate for General Engineering Purposes — Specification (Fourth Revision). BIS's notification states that IS 736:1986 remains concurrently in force until its scheduled withdrawal on
6 April 2027. The applicable standard and transition requirements should therefore be checked carefully before applying for certification. <Cite refs={["turn815677search0","turn815677search7"]}/>
Qualitance India provides consultancy support for BIS product certification, documentation, testing coordination, factory readiness and regulatory compliance.
1. What Is Wrought Aluminium and Aluminium Alloy Plate?
Wrought aluminium plates are flat products manufactured by mechanically working aluminium or aluminium alloys, typically through rolling and related processing operations.
The applicable alloy designation, temper condition, thickness and mechanical properties determine whether a plate is suitable for a particular application.
Common industrial applications include:
- General engineering and fabrication
- Industrial machinery and equipment
- Structural and fabricated components
- Transportation and automotive components
- Equipment housings and enclosures
- Industrial platforms and other engineered assemblies
The precise application depends on the alloy composition, temper, dimensions and performance requirements of the finished product.

3. Is BIS Certification Mandatory for Wrought Aluminium Plates?
The Aluminium and Aluminium Alloy Products Quality Control framework includes wrought aluminium and aluminium alloy plates for general engineering purposes under IS 736. The product is listed in the BIS Scheme-I compulsory certification framework. <Cite refs={["turn306438search18","turn306438search2"]}/>
However,
the scheduled enforcement date shown on the BIS upcoming QCO page is 1 December 2026 for this product. As of 24 October 2026, that date is still in the future. Manufacturers should verify the latest official notification and any subsequent amendment or deferment before relying on this date for compliance planning. <Cite refs={["turn815677search1"]}/>
Businesses should prepare in advance rather than waiting until the enforcement date approaches.
Key compliance considerations include:
- Identifying whether the product falls within the QCO description.

4. Important Technical Requirements Under IS 736
IS 736 addresses the technical requirements for wrought aluminium and aluminium alloy plates intended for general engineering purposes. The product manual for the 1986 edition identifies several important areas of evaluation. The exact requirements must be checked against the edition applicable to the product. <Cite refs={["turn306438search17","turn306438search5"]}/>
Chemical composition
Chemical composition is important for confirming the alloy designation and material characteristics.
Depending on the alloy, the applicable requirements can include limits for aluminium and alloying or impurity elements such as copper, magnesium, silicon, iron, manganese and zinc. Other elements may be relevant to particular alloy designations.
Mechanical properties
Mechanical testing establishes whether the plate meets the prescribed performance requirements for its specified alloy and temper.
The BIS LIMS listing for IS 736 identifies tests including:
- 0.2% proof strength
- Tensile strength
- Elongation
<Cite refs={["turn306438search5"]}/>
Condition or temper
The product manual for IS 736:1986 identifies temper conditions including M, O, H2, W and WP. The required condition must be consistent with the specified alloy and the intended product properties. The latest edition should be checked for its current terminology and requirements. <Cite refs={["turn306438search17"]}/>
Dimensions and tolerances
Plate dimensions must conform to the applicable requirements, including relevant dimensional tolerances.
Manufacturers should maintain measurement arrangements and production controls capable of demonstrating conformity for the sizes included in the proposed licence scope.
Freedom from defects
The plate should meet the applicable requirements relating to surface condition and freedom from defects. Manufacturing inspection and documented acceptance criteria help establish consistent product quality.
Marking and traceability
Manufacturers should maintain appropriate identification and traceability of product batches, alloy designations and temper conditions. The use of the BIS Standard Mark is subject to the licence and applicable marking requirements.
5. BIS Product Testing Requirements for Aluminium Plates
Product testing is an important part of the BIS certification process. The test plan should be developed using the applicable standard edition, product manual and certification requirements.
Typical test categories identified in the BIS LIMS listing for IS 736 include the following:
| Test category |
Purpose |
| Chemical composition |
Verify conformity with the specified alloy designation |
| 0.2% proof strength |
Evaluate resistance to permanent deformation |
| Tensile strength |
Assess tensile performance |
| Elongation |
Evaluate deformation before fracture |
| Dimensions and tolerances |
Confirm dimensional conformity |
| Freedom from defects |
Evaluate product condition against applicable requirements |
<Cite refs={["turn306438search5"]}/>
The exact test methods, acceptance limits and sample requirements must be confirmed against the applicable edition of IS 736 and its amendments. Do not assume that a test plan prepared against IS 736:1986 will automatically satisfy IS 736:2026.
How much sample is required?
The BIS product manual for IS 736:1986 contains sampling and grouping guidelines. It explains that plates are grouped according to alloying characteristics and that samples may be selected from higher-purity or higher-alloy-content designations within a group, subject to the stated conditions.
It also specifies that separate samples are required for each intended temper condition within the relevant grouping arrangement. A sample of any size may be used for the stated grouping purpose, and separate samples for every plate size are not necessarily required under those guidelines. The manufacturer must nevertheless have the required manufacturing and testing facilities for the varieties included in the licence. <Cite refs={["turn306438search17"]}/>
These are guidelines from the 1986-edition product manual. Confirm the current sampling requirements with BIS before applying them to a new application under IS 736:2026.
Where can manufacturers check testing laboratories and charges?
The official BIS Laboratory Information Management System lists laboratories and testing information for IS 736.
For example, its search results show a listing for National Test House, Ghaziabad, with an indicated test charge of ₹11,000 excluding taxes for the listed scope. Other laboratories and test scopes may have different charges. The actual cost depends on the required tests and the applicable laboratory arrangement. <Cite refs={["turn306438search5"]}/>
