This certification process thoroughly assesses chemical composition, mechanical properties, and performance tests to ascertain that the products conform to the IS requirements.

Overview of BIS Certificate for Aluminum Sheets and Plates

In India, a BIS Certificate guarantees that the goods are superior, safe, and consistent. Specifically speaking, IS 736 and IS 737 are covered by Scheme I of BIS, which guarantees that the goods made available for consumption meet extremely stringent safety and performance requirements established by the government. The ISI certification mark attests to the items' compliance with all requirements. Ultimately, BIS licensing would increase consumer confidence while ensuring that the goods adhered to legal requirements. To maintain product standards and guarantee continuous compliance, the Bureau of Indian Standards follows a rigorous process to provide the license, making it trustworthy.

Recent Changes to IS 736 and IS 737 Standards: What Manufacturers Need to Know (QCO)

According to the latest QCO issued by the Ministry of Commerce and Industry concerning the Bureau of Indian Standards, it stated the exclusion of locally manufactured products for export, eliminating some standards. Micro and small enterprises, however, must comply with the set rules by Indian Standards according to the dates indicated in the order. Imported goods, on the other hand, that may reach up to 200 kilograms per year and are strictly for research purposes by aluminium product manufacturers are an exception only if they are not commercially sold and disposed of as scrap. The certifying authority is the Bureau of Indian Standards (BIS), and violating such an order under the BIS Act, 2016 is punishable.

Testing Process for both the IS 736 and IS 737 

Testing under the BIS Certification, through IS 736 and IS 737, involves some very important quality and performance verification checks to ascertain whether these aluminum sheets and plates guarantee safety, strength, and durability. There are different tests involved under each of these standards: overview in the following list:

IS 736 Testing Procedure

BIS certification for IS 736 has been applied to wrought aluminum and aluminium alloys, which have generally been used for general engineering purposes, with an emphasis on basic mechanical and chemical properties.

1. Chemical Composition Test: This test is for establishing the alloying elements and the purity of aluminum under specified compositions intended for IS 736. This includes silicon, magnesium, iron, and copper.

2. Tensile Strength Test: Determines resistance to tensile forces; it is a measurement against deformation or fracture. That is crucial in determining whether aluminum will meet its strength requirement for general application in engineering.

3. Elongation Test: A test on the ductility of the material through elongation before break. It is a measure where material with a high elongation value can resist stress without cracking.

4. Hardness Test: it deals with resistance to deformation at the surface. The test requires aluminium to be sufficiently hard for its intended application but not brittle.

5. Dimensional Accuracy: It is testing the thickness and width to confirm sheets and plates of specific thickness and width and size and form within a specified tolerance.

IS 737 Testing Process

BIS certification for IS 737 is relevant to high-strength aluminum alloy sheets and plates, especially those used in structural and aerospace applications. Testing for IS 737 includes stricter and additional tests compared to IS 736.

1. Chemical Composition Test: Similar to IS 736, this test ensures that the specific alloy composition meets IS 737 standards, especially for elements that contribute to high strength and corrosion resistance.

2. Tensile and Yield Strength Test: IS 737 requires high tensile and yield strength. These tests measure how much stress the material can handle before it begins to deform (yield) and ultimately breaks (tensile).

3. Fatigue Test: It measures the number of times a material can undergo repeated stress cycles without failure. This test is significant for structural applications since materials are subjected to constant loading and unloading.

4. Impact Resistance Test: This test determines the energy absorbed by the material when subjected to a sudden impact. High impact resistance is important for products used in structural or high-stress applications so that they do not break easily when force is applied.

5. Corrosion Resistance Test: This is the corrosion resistance test of aluminum alloy in different environmental conditions. IS 737 products should be resistant to elements that may cause deterioration, especially when they are used in aerospace or outdoors.

6. Flatness and Dimensional Accuracy: IS 736 indicates the sheets and plates shall not have tolerances of thickness and flatness for them to remain structurally sound and fit in the assembly.

7. Final Inspection and Certification: Once all tests are successfully conducted and the aluminum products conform to IS 736 or IS 737, the test reports are submitted to BIS for verification. After BIS verifies compliance, a license is issued that allows the use of the ISI mark.

The Process of attaining ISI Mark on the products with IS 736 and IS 737

With these procedures, the manufacturer can get the ISI mark for its aluminum sheets and plates. It increases the credibility as well as market acceptance of this product.

1. Application Submission: The application must be submitted through the BIS portal and it is about the information related to the aluminum sheets or plates. All the information regarding the product specifications, manufacturing process, and even quality checks must be documented. 

2. Document Preparation: There may be test reports, certifications regarding quality management, or even specifications for IS 736 and/or IS 737. There is evidence that the produced product adheres to certain requirements. 

3. Product testing: A proper evaluation test shall be conducted under the BIS-accredited laboratory of the product. In the case of IS 736, the main test concentrates on general mechanical properties and formability, whereas IS 737 focuses on high-strength properties with tensile strength and the aspect of corrosion resistance. It can guarantee compliance by standards relevant once the tests conducted have been satisfactory.

4. Factory Inspection: BIS officials visit the place to check whether the production process and the quality control practices in use are as per the standards followed by IS. They inspect whether the manufacturing process adheres to the technical standard required for the ISI mark. 

5. License Grant and ISI Mark Certification: On fulfillment of all these requirements, BIS grants a license for permission to use the ISI mark on the product. The mark of ISI on the product provides an assurance of meeting quality requirements under IS 736 or IS 737.

6. Continuous Compliance and Renewals: This usually stands valid for a certain duration, and renewal is required over a period. To remain certified, manufacturers ensure that products remain in conformity with the standards of BIS and continue having periodic testing and audits.

Benefits of BIS-Certified Aluminum Sheets and Plates Under IS 736 and IS 737

The advantages of the BIS ISI mark for aluminum sheets and plates are as follows:
