BIS ISI Certification for Line Operated Three-Phase AC Motors IS 12615:2018
Line operated three-phase AC motors are widely used in industrial machinery, manufacturing plants, pumping systems, compressors, and other heavy-duty applications. These motors are designed to deliver reliable mechanical power while maintaining high energy efficiency across various industrial operations.
Indian Standard IS 12615:2018 specifies the requirements for energy efficient three-phase squirrel cage induction motors. The standard covers motors with different pole configurations including 2, 4, 6, and 8 poles and frame sizes ranging from 71 up to 315L. These motors typically operate at voltages up to 1000 volts and output ratings from 0.12 kW to 1000 kW.
BIS ISI Mark Certification under IS 12615:2018 ensures that line operated three-phase AC motors meet the required safety, performance, and energy efficiency standards defined by the Bureau of Indian Standards (BIS). It allows manufacturers to legally use the ISI mark and sell compliant motors in the Indian market.

Overview of ISI Mark Certification for Line Operated Three-Phase AC Motors
Electric motors are one of the most important components in industrial electrical systems. Motor-driven systems account for nearly 70 percent of the total electricity consumption in many industrial facilities. Therefore, ensuring the energy efficiency and operational safety of motors is critical for reducing energy costs and improving system performance.
IS 12615:2018 establishes energy efficiency requirements and performance parameters for line operated three-phase squirrel cage induction motors. The standard ensures that motors are designed and manufactured to achieve high efficiency levels while maintaining safe operation under industrial working conditions.
BIS ISI certification under the Product Certification Scheme confirms that the motor meets all required technical specifications, testing parameters, and quality control standards. Manufacturers must demonstrate proper manufacturing infrastructure, quality assurance systems, and testing capabilities before BIS grants permission to use the ISI mark.
Process Required for BIS ISI Mark Certification for Three-Phase AC Motors (IS 12615:2018)
Manufacturers seeking BIS ISI certification for line operated three-phase AC motors must follow the BIS Product Certification Scheme (Scheme I). This certification verifies that the motors comply with the technical and energy efficiency requirements specified under IS 12615:2018 before they are introduced into the Indian market.
Estimated Timeline: The BIS ISI certification process generally takes around 30 to 45 days depending on the factory inspection schedule, sample testing process, and documentation verification.
Step-by-Step Certification Process
- Application Submission: The manufacturer submits the BIS application through the Manak Online portal with product details, applicable standard (IS 12615:2018), manufacturing facility information, and quality control documentation.
- Product Testing Preparation: The manufacturer must ensure testing arrangements for performance parameters such as insulation resistance, temperature rise, winding resistance, and efficiency verification.
- Factory Inspection: BIS officials conduct a factory inspection to evaluate production facilities, quality control systems, and in-house testing infrastructure.
- Sample Testing: Product samples are collected during inspection and tested in BIS-recognized laboratories according to the testing methods defined in IS 12615:2018.
- Grant of BIS License: After successful inspection and satisfactory test results, BIS grants the Certification Marks License (CM/L), allowing the manufacturer to affix the ISI mark on three-phase AC motors.
Requirements to Obtain BIS License for Three Phase AC Motors (IS 12615:2018)
