Line-operated three-phase AC motors are widely used in industrial and commercial
applications to run machines such as pumps, compressors, conveyors, and other heavy
equipment. These motors are known for their high efficiency, reliable performance, and
ability to operate continuously under load.
To ensure safety, performance, and energy efficiency, these motors must comply with IS
12615:2018, a standard set by the Bureau of Indian Standards. BIS certification
confirms that the motor meets required quality standards, making it suitable for use in
the Indian market.
Who Needs BIS Certification for Three-Phase AC Motors?
BIS certification under IS 12615:2018 is required for businesses involved in
manufacturing, importing, or selling line-operated AC motors in India.
Applicable to:
- Manufacturers of AC motors
- Importers bringing motors into India
- Brand owners selling motors under their name
What is IS 12615:2018
This is the Indian Standard that defines the energy efficiency and performance
requirements for three-phase AC motors used in industrial and commercial applications.
This standard is set by the Bureau of Indian Standards to ensure that motors are:
- Energy-efficient and consume less power during operation
- Reliable for continuous industrial use
- Designed to deliver consistent performance under load
- Built with proper insulation and safety features
Testing and Inspection Requirements for Three-Phase AC Motors
To ensure proper performance, energy efficiency, and electrical safety of line-operated
AC motors, the Bureau of Indian Standards defines detailed testing and inspection
requirements under IS 12615:2018 during manufacturing.
What are R and S?
- R (Required): Test must be conducted in the manufacturer’s in-house lab
- S (Subcontracting Allowed): Test can be conducted in BIS-approved or
NABL-accredited external labs
Electrical & Safety Tests
- Insulation Resistance Test (R) – Ensures proper insulation between windings
and body
- High Voltage Test (R) – Verifies insulation can withstand high voltage safely
- Earthing Test (R) – Ensures proper grounding for electrical safety
- Protection Against Electric Faults (R) – Prevents leakage and electrical
hazards
Performance & Efficiency Tests
- No Load Test (R) – Checks motor performance without load
- Power, Current & Efficiency Test (S) – Measures energy efficiency and power
consumption
- Full Load Test (S) – Evaluates performance under actual working conditions
- Locked Rotor Test (S) – Checks current and torque during starting condition
- Temperature Rise Test (S) – Ensures motor does not overheat during operation
Mechanical & Functional Tests
- Speed & Rotation Test (R) – Verifies proper motor speed and rotation
- Torque Test (S) – Checks pull-up and load-handling capability
- Vibration & Noise Test (S) – Ensures smooth and stable operation
BIS Certification Process for Three-Phase AC Motors
The BIS certification process ensures that these AC motors meet the required
standards for proper and efficient operation. This process is defined by the Bureau of
Indian Standards (BIS) and includes the following steps:
- Online Registration:Manufacturers register on the BIS Manak Online Portal by submitting company details, factory information, and product specifications. Foreign manufacturers must appoint an Authorized Indian Representative (AIR) in India.
- Testing at BIS-Approved Laboratory:Product samples are tested in BIS-approved laboratories to evaluate electrical safety, insulation resistance, heating efficiency, durability, and overall performance as per requirements.
- Application Submission:application is submitted along with laboratory test reports, technical documents, manufacturing process details, and factory information. Foreign manufacturers must also provide AIR-related documents.
- Factory Inspection: BIS officials conduct an on-site inspection of the manufacturing unit to verify production processes, quality control systems, safety measures, and compliance with the standard.
- Grant of BIS License:If all requirements are successfully met, BIS issues the certification license under Scheme-I, allowing the manufacturer to produce and sell certified products.
- Use of ISI Mark:After certification approval, the manufacturer is permitted to use the ISI mark along with a CM/L number on the product, confirming compliance with the standard.
