- Pre-painted aluminium-zinc coated steel sheets require BIS certification as per IS 15965:2012.
- The standard defines the substrate, coating, and paint durability classes.
- Confirmation is obtained through sample testing in the laboratory, document verification, and BIS inspection.
- The misuse of grades without test records is frequently cited as the most significant mistake.
- Certification results in increased compliance, trust, and wider market edments-process access.
Introduction
A roofing sheet manufacturer in Pune had to bear the loss of a significant order due to the absence of a BIS-approved product—an expensive lesson about the importance of the certification process. Manufacturers of pre-painted aluminium-zinc alloy metallic coated steel strip and sheet (plain) must comply with IS 15965:2012 as if it were mandatory. Getting this certificate is a way of confirming that the product meets the standards for corrosion resistance, paint durability, and product performance set by India. Besides that, it facilitates easy entry to the market, safeguards against the risk of regulations, and, most importantly, provides customer reassurance in a highly competitive steel sector.

What is IS 15965:2012?
IS 15965:2012 is an Indian Standard that specifies the requirements for pre-painted aluminium-zinc alloy metallic coated steel strip and sheet (plain). Simply, it reveals the content of the metal, the coating, the paint life, the various methods of corrosion resistance measurement and recording for a long time. The paper cited is the source of the specification for the manufacturers of the coated steel whose products are mainly used for roofing, facades, and other building works. ISI MARK
Key Points:
- The standard limits its scope to only plain pre-painted aluminium-zinc alloy coated steel sheets and strips.
- The metal for the base must be of the standard of IS 15961:2012.
- The standard specifies the coating thicknesses like AZ70, AZ150 and AZ200 among its requirements.
- Furthermore, it sets out the surface tests for the strength, impact, salt spray and humidity.
- What primarily the standard is about is product quality, durability, and certification by BIS compliance.
Why is BIS Certification Mandatory
A BIS certification would be the mandatory one to establish that the products that are available in the Indian market are of a certain standard with regard to safety, quality, and performance. The certification for pre-painted aluminium-zinc alloy metallic coated steel strip and sheet (plain) as per IS 15965:2012 is the evidence that the material has been made by the approved methods and has passed all the tests for corrosion resistance, coating strength, and durability.
Key Reasons:
- It safeguards the public and makes the products reliable when used in the construction and manufacturing industries.
- Stops trading or importing of substandard or unsafe steel products.
- Consumers and buyers are enabled to trust the product through the ISI mark.
- Manufacturers are assisted in meeting the requirements of the Ministry of Steel’s Quality Control Orders.
- Helps in getting govt tenders, exports, and large infrastructure projects.
Importance and Benefits of BIS Certification
| Importance | Benefits |
| Ensures product meets IS 15965:2012 quality and safety standards | Improves product reliability and performance in real-world use |
| Mandatory compliance under the Ministry of Steel’s Quality Control Order | Prevents legal penalties and market restrictions |
| Confirms corrosion resistance, coating adhesion, and durability | Reduces product failure, warranty claims, and rejections |
| Establishes manufacturer credibility and trust | Enhances brand reputation and buyer confidence |
| Enables participation in government and large infrastructure projects | Expands business opportunities and market access |
| Promotes standardization across manufacturing processes | Helps maintain consistent production quality and efficiency |
Step-by-Step Process of BIS Certification
Step1:Documentation
- Gather all the papers of your business and products (such as your factory license, test reports, and QC stuff).
- Instruction: verify once more that the product name, model, factory address, etc. are identically stated on all the documents.
- Prepare your quality control manuals along with the description of the in-house testing procedures.
- Make copies of all these documents and upload them with your first BIS application on their online portal.
Step2:Product Testing
- Take the samples to be tested in a lab that is approved by BIS for your Indian Standard (for example IS 15965:2012).
- The tests are done for the thickness of the coating, the strength of the adhesive, the resistance to wear, and eventual rusting, etc.
- Every sample should be conforming to the requirements of the standard.
- You will receive an official test report (following the BIS layout) that you will send together with your application.
Step3:Application Submission
- Register on the BIS Manak Online Portal and fill out Form-V.
- Upload all supporting documents, including test reports and factory details.
- Pay the applicable BIS processing and application fees.
- Track application status regularly to respond promptly to any BIS queries.
Step4:Scrutiny and Inspection
- BIS personnel physically go through your application, documentation, and test reports to check the correctness.
- It is planned to have a factory visit to see production processes and testing facilities.
- Inspectors also verify the traceability of raw materials, calibration of instruments, and testing done in-process.
- Non-conformities found have to be fixed before getting final approval.
Step5:Grant of License
- On inspection and review being successful, BIS grants the permission to use the Standard Mark (ISI mark).
- The license details the product standard (e.g., IS 15965:2012), grade, and scope.
- Now, the manufacturers are allowed to put the ISI logo on their products that meet the requirements.
- This is a continuous process, and the validity of the license is subject to regular surveillance audits and periodic product testing.
