The efficiency of electrical machinery greatly depends on the quality of winding wires used in the manufacture of motors, transformers, generators and electrical machines. Inconsistency or poor quality of enamelled copper wire may cause such problems like insulation failure, overheating, power loss, and breakdown of electrical machinery. BIS certification of Polyesterimide Enamelled Round Copper Wire, Class 180, IS 13730 (Part 8):2014 is an initiative that has been established in response to these challenges.
For manufacturers as well as importers of polyesterimide enamelled round copper wire, BIS certification is very crucial. This is because the requirements set out in IS 13730 (Part 8):2014 define specific parameters relating to the resistance of enamelled winding wires as well as their ability to withstand certain temperature conditions.
This is the Indian Standard for polyesterimide enamelled round copper wire, class 180, used in electrical windings for motors, transformers, and other electrical equipment. The standard defines requirements for electrical insulation, thermal endurance, mechanical strength, and surface quality to ensure reliable performance under continuous electrical load. As per BIS (Bureau of Indian Standards), these enamelled copper wires are:
BIS authorisation under IS 13730 (Part 8):2014 is required for businesses involved in manufacturing, importing, or supplying Class 180 Polyesterimide Enamelled Round Copper Wire in India.
Applicable to:
To ensure consistent quality of polyesterimide enamelled round copper wire, class 180, the Bureau of Indian Standards specifies requirements under IS 13730 (Part 8):2014. This certification ensures that manufacturers maintain proper electrical insulation, thermal resistance, mechanical strength and coating uniformity for reliable performance in motors, transformers and electrical windings. The BIS testing parameters and quality checks for Class 180 enamelled copper wire are listed below:
Certification procedure makes sure that Polyesterimide Enamelled Round Copper Wire, Class 180 (IS 13730 (Part 8):2014) complies with all necessary standards of insulation properties, heat resistance, mechanical strength and operational efficiency. The certification procedure controlled by the Bureau of Indian Standards (BIS) is important for maintaining the consistency of winding wires. The BIS product approval steps are provided below:
The Foreign manufacturers must designate an Authorized Indian Representative (AIR) in India. The representative is the local point of contact for the Bureau of Indian Standards (BIS) and manages all compliance and regulatory requirements in India.
Once the certificate for BIS is issued, the ISI mark for class 180 enamel round copper wire needs to be stamped on each spool, roll or packaging piece. Other important details like the manufacturer's name, diameter of conductor, class/grade of copper wire and BIS licence number (CM/L) should also be mentioned while marking. Additional details are provided below:
Note: Marking is typically applied using durable stamping, tagging, or permanent printing to ensure clear identification during handling, storage, and transportation, as per BIS marking requirements.
The charges for certification under BIS for enamelled winding round copper wire involve expenses for application, product category testing, manufacturing plant inspection, license issuance, and marking license. The costs may be incurred as per the rules laid down by Scheme I of BIS (Conformity Assessment) regulations.
Note:
Compliance requirements are directly related to product safety, performance efficiency, and industry integrity. Compliant with IS 13730 (Part 8):2014 will make sure that polyesterimide enamelled copper wire products undergo rigorous testing for quality insulation, heat resistance, wear and tear resistance, and sustained stability with thermal classification Class 180. Not only will this add to the reliability of the product but also guarantee optimal performance in terms of electrical applications.
In light of the increasing requirement for high-performing electrical products in various industries, the relevance of the BIS certification of enamelled winding wires becomes more and more important. Securing BIS certification according to the standard IS 13730 (Part 8): 2014 will help companies gain an advantage in the market and stay compliant with Indian standards in the long run. EVTL India can help companies obtain their BIS certification.
