BIS Certification of Polyester Enamelled Round Copper Wire Class 155 as specified in IS 13730
(Part 3):2012 deals with tests on an electrical conductor that is used in the production of motors,
transformers, generators and other electromechanical appliances. It comprises an insulated
conductor made of copper wire that is provided with an enameling layer of polyester with
thermal endurance up to class 155 insulation level. This enables the electrical conductor to bear
heavy electrical loads along with high temperatures.
IS 13730 (Part 3):2012 defines requirements concerning conductor size, thickness of enamel,
thermal endurance, breakdown voltage, and mechanical properties. These factors are analyzed
systematically by the Bureau of Indian Standards (BIS) to certify the products for their sale in
India.
What is IS 13730 (Part 3):2012
IS 13730 (Part 3) is the Indian Standard for Polyester Enamelled Round Copper Wire, Class
155, used in electrical equipment such as motors, transformers, generators, and other winding
applications. It specifies the performance, insulation and quality requirements to ensure reliable
electrical and mechanical performance under operating conditions. As per the Bureau of Indian
Standards (BIS), these enamelled copper wires are:
- Evaluated for thermal endurance
- Tested for electrical performance
- Checked for conductor dimensional conformity
- Assessed for insulation quality

Testing and Inspection Requirements
For uniform quality assurance of the enamel-coated conductors used in electrical applications,
the Bureau of Indian Standards specifies the basic requirements of the product in IS 13730
(Part 3):2012. It guarantees quality insulation properties, conductive capabilities, thermal
stability, and strength of the conductor material.
The BIS testing parameters and quality checks for the Copper Wire are listed below:
BIS Scheme-I Approval Process under IS 13730 (Part 3):2012
The BIS Authorisation process ensures that the Class 155 Electrical Winding Wire meet the
required standards for efficient operation. This process is set by the Bureau of Indian Standards
(BIS) and includes the following steps:
- Online Registration: Manufacturers register on the BIS Manak portal by submitting company, factory, and product details. Foreign manufacturers must appoint an Authorized Indian Representative (AIR).
- Testing at BIS-Approved Laboratory: Product samples are tested in BIS-approved laboratories for moisture content, fibre level, purity, nutritional composition and absence of contaminants.
- Application Submission: The application is submitted along with test reports, technical documents, and factory details. Foreign manufacturers must also submit AIR-related documents.
- Factory Inspection: Officials from the BIS come to the manufacturing unit to evaluate production processes, safety measures, and the quality control system.
- Grant of BIS License: Once all compliance procedures have been satisfactorily met, the certification license is granted by BIS under Scheme I.
- Use of ISI Mark: Following approval, the manufacturer is authorized to use the ISI Mark on the product along with a valid CM/L number, confirming that the product meets BIS standards.
