BIS CERTIFICATION FOR UNITARY AIR CONDITIONERS
IS 1391 (PART 1):2017

IS 1391 (Part 1): 2017 covers room air conditioners-unitary air conditioners. This standard specifies the design and performance requirements for unitary air conditioners. This standard also specifies the test conditions and procedures for determining various performance characteristics of unitary air conditioners that operate nonfrosting when cooling and dehumidifying at standard rating settings. This standard covers unitary air conditioners that can also function as heaters through the use of a heat pump or an electric heater.

Unitary air conditioners are classified based on their function and nominal cooling capacity.

1. Classification based on Function
• Cooling and Dehumidification
• Cooling and Heating by Heat Pump
• Cooling and Heating by Electric Heater
2. The nominal cooling capacity of unitary air conditioners should be classified as follows: 1500, 2250, 3000, 3750, 4500, 6000, 7500 and 9000 kcal/h.

The manufacturer must ensure that the product meets the standard's general, construction, and performance requirements. The air conditioner and its components must be built with enough strength and rigidity to withstand regular handling, transit, and operation conditions. There shall be no sharp edges or corners that could cause injury under normal usage conditions and all moving elements that could cause an accident shall be effectively guarded. Parts that need to be serviced regularly must be easily accessible.

Materials used in the construction of cabinets, front panels, and so on must comply with the equivalent Indian Standards wherever applicable unless modified by this standard. The material shall be free from defects that are likely to cause undue deterioration or failure.

tests

The following test shall be carried out for unitary air conditioners.

• Pressure test
• High Voltage Test
• Leakage Current Test
• Earth Resistance test
• Cooling Capacity test
• Power factor test
• Freeze up test
• Maximum Heating Performance Test
• Sound test
• Power consumption test

Labelling and marking shall be done in accordance with IS 1391 (Part 1): 2017. Conforming to the requirements of IS 1391( Part 1):2017, the product may be certified under the terms of the Bureau of Indian Standards Act, 2016 and the Rules and Regulations formulated thereunder, and the product may be marked with the Standard Mark (ISI Mark). The Manufacturer must obtain a BIS license from the Bureau of Indian Standards to use a standard mark (ISI Mark). The BIS grants a license based on a successful assessment of manufacturing infrastructure, quality control, testing capabilities, and production process.
