BIS Certification for Finned Type Heat Exchanger for Room Air Conditioner – IS 11329
If you are a manufacturer of Heat Exchanger for Room Air Conditioner, BIS certification as per IS 11329 is mandatory. In the room air conditioners, Finned Type Heat Exchangers are important components which are used for efficient heat transfer between the refrigerant and air. These heat exchangers are essentially coils in both the evaporator and condenser and play a direct role in the performance, energy efficiency, longevity and reliability of air conditioners. The main reason for the performance of an air conditioner is the quality and efficiency of the heat exchanger and therefore one has to adopt strict manufacturing and testing conditions. That is why, BIS Certification for Finned Type Heat Exchangers for Room Air Conditioners, as per IS 11329 has great significance. It helps to ensure that heat exchangers when manufactured and supplied in the Indian market are compliant to the Indian standards in terms of quality, performance, safety and reliability.
What is BIS Certification for Finned Type Heat Exchangers?
The Bureau of Indian Standards (BIS) is the national standards body of India which aims to formulate and enforce the quality standards for products produced, imported and sold in India. Finned Type Heat Exchangers are subjected to BIS Certification for compliance with IS 11329 which lays down the general requirement & method of test for finned type heat exchanger for various type & capacity room air conditioners. This standard addresses design, construction, manufacturing requirements, performance characteristics and testing procedures.
The manufacturers who receive ISI Certification can affix ISI mark on their product which are Finned Type Heat Exchangers. The ISI mark is a reliable assurance of quality and compliance that gives assurance to air conditioner manufacturers, OEMs, distributors and regulatory authorities that the product has been tested and inspected as per Indian Standards.
