- It is compulsory to have a BIS certification under IS 3024:2015 for CRGO electrical steel sheet and strips in India.
- The standard commits quality through measures of core loss, magnetic strength, and insulation coating.
- Getting certified means a facility is subjected to audits, testing, and BIS licence approval.
- The use of certified CRGO is a step forward in energy efficiency and also enhances the company’s credibility in the market.
- Starting the preparations early allows you to be in control of the technical and documentation aspects.
Introduction
A Pune-based transformer manufacturer was on the edge of a loss-making situation with their impounded consignment of CRGO steel because it did not have a BIS-certified product under IS 3024:2015. In India, certification of this nature is not a matter of choice–it is a legal requirement laid down by the Quality Control Order. CRGO, which is grain-oriented electrical steel, is the most essential component for transformer cores and is the main factor that determines energy efficiency. The BIS mark is the guarantee that every sheet or strip conforms to the set performance and safety standards. Bureau of Indian Standards
What is IS 3024:2015?
This standard IS 3024:2015, is a specification of the Indian Bureau of Indian standards, which describes the physical, performance, and test requirements for grain-oriented electrical steel sheet and strip (CRGO). The standard defines a CRGO material that meets the magnetic and mechanical properties required for an efficient energy performance of transformers or electrical equipment.
Key Points:
- Includes material requirements for fully processed grain-oriented electrical steel sheets and strips.
- Defines the core loss, magnetic induction, stacking factor, and the quality of the insulating coating.
- Leads to stable performance and low energy losses in transformer cores.
- Domestic manufacturers and importers of CRGO material are required to comply with this standard.
- It is a mandatory requirement under the Steel and Steel Products (Quality Control) Order to be approved in the Indian market. ISI MARK
Why is BIS Certification Mandatory
- It is definitely a must for CRGO sheets and strips to conform to Indian quality and safety standards.
- By doing so it ensures that substandard or non-compliant materials are not allowed to enter the market.
- Enables the magnet performance to be dependable and energy losses to be very low in transformers.
- BIS certification also acts as a legal permit for manufacturing and importing CRGO in India.
- It is a great means of consumer confidence and is in line with the government’s energy-efficiency goals.
Importance & Benefits of BIS Certification
| Importance | Benefits |
| Ensures product quality and compliance with IS 3024:2015 standards | Guarantees reliable performance and durability of CRGO materials |
| Mandatory for legal manufacturing and imports in India | Provides smooth market entry and avoids regulatory penalties |
| Maintains uniformity across domestic and imported products | Builds brand credibility and customer confidence |
| Supports India’s energy efficiency and safety goals | Reduces transformer losses and enhances operational efficiency |
| Strengthens supply chain transparency and accountability | Increases business opportunities in domestic and export markets |
Step-by-Step Process of BIS Certification
Step1:Documentation
- Collect company registration, factory details, and product specifications.
- Work out quality management system (QMS) figures and also test procedures that explain the methods of testing.
- Make sure that all the papers fit well with BIS formats and regulations.
- Prepare your files in both formats i.e., soft and hard copies, ready for submission and audit reference.
Step2:Product Testing
- Have product samples tested at a BIS-accredited lab.
- Carry out all tests strictly following the Indian standard relevant to the product (e.g., IS 3024:2015 for CRGO).
- When the reports are in, do not forget to check from the certificate that all tests have been performed and then send them to the authorities.
- Maintain a record of the samples upon which tests were conducted and also keep the duplicate copies of the reports.
Step3:Application Submission
- The application to the BIS is made by filing the form on the online portal.
- Present all the necessary documents and test certificates at the same time.
- Submit Application and Test Fees through the corresponding money.
- The status of the application may be monitored through an online portal. Furthermore, BIS queries can be quickly answered by the concerned person.
Step4:Scrutiny and Inspection
- BIS officials verify the applicant’s documents and test reports that have been submitted.
- Production and quality control are verified through a factory visit.
- Before the approval phase, it is very important to ensure that you have rectified the non-conformities that were pointed out.
- The goal of the inquiry is to confirm that the manufacturing processes are as per the documentation.
Step5:Grant of License
- Once the inspection results and the test reports are favorable, BIS issues the licence.
- The manufacturer gets the permission to use the ISI mark on the product.
- The licence is like a contract that holds information about the scope, product standard, and period of validity.
- There are unannounced inspections to make sure that the company is abiding by BIS norms regularly.
Documents required for BIS Certification
| Category | Documents Required |
| Company Details | Incorporation certificate, GST, PAN |
| Factory Information | Layout plan, machinery list, process flow |
| Authorized Signatory | Authorization letter, ID proof |
| Product Details | Technical specs, drawings, label sample |
| Testing Documents | BIS-approved lab test reports |
| Quality Control | QC manual, calibration, test records |
| Raw Materials | Supplier certificates, material traceability |
| Importers (if any) | IEC code, manufacturer authorization |
Timelines, Costs, Validity & Renewal
- Timelines: The waiting time may be up to 60 days for Indian residents while for non-residents it will be roughly 6 months.
- Costs: Are inclusive of the fees for the application, the examination, and the audit.
- Validity:Valid for two years.
- Renewal:Renew every two years with updated reports and fees.
