IS 8148:2018 addresses ducted and package air conditioners, delineating their constructional and performance criteria. This standard outlines methodologies for rating packaged air conditioners with nominal cooling capacities of 10,000 W and above, which operate without frosting during cooling and dehumidifying at standard rating conditions. Ducted and package air conditioners are self-contained encased assemblies crafted to provide unhindered distribution of conditioned air within enclosed spaces, rooms, or zones.

When creating certification grouping guidelines based on IS 8148:2018, the following factors are considered:

1)Classification based on function and construction:

• Ducted/Packaged heat pump units for Cooling and Heating with Air-cooled condenser

• Ducted/Packaged Air Conditioner units for Cooling only with Air-cooled condenser

• Ducted/Packaged Air Conditioner units for Cooling only with water-cooled condenser

2)Classification based on product type:

• Indoor unit (IDU) only

• Outdoor unit (ODU) only

• Ducted/Package Air Conditioners (Both IDU and ODU)

Manufacturers are responsible for ensuring their product meets the standard's general, constructional, and performance criteria. The unit should be constructed with sufficient strength and rigidity to withstand routine manual and mechanical handling, transportation, and operation without experiencing damage or failure. It must successfully undergo the mechanical strength test outlined in the standard. Any components necessitating regular cleaning or maintenance should be easily accessible when the unit is installed following the manufacturer's instructions. Additionally, units should be devoid of excessive noise and vibration.

Pipes and connections to moving or resiliently mounted parts must be arranged to prevent fouling or excessive transmission of vibrations to other components. They should be designed to avoid fatigue-induced failure. Ratings published or reported to meet this standard should be based on conditions specified within the standard. The performance of any production unit should have a capacity not less than 90 percent of the stated capacity.

TEST

Tests shall be classified into three categories:

1. Production routine tests

   • Running Test

   • Pressure Test or Leakage Test

   • Electric Strength Test

   • Earth Continuity Test

   • Maximum Operating Conditions test

    

2. Type tests

3. Acceptance tests

The manufacturer must specify the product type, function, construction, and cooling capacity intended to be covered under the license. Outsourcing of both indoor and outdoor units (IDU and ODU) is not allowed for obtaining a BIS license for ducted/package AC certification according to IS 8148.

Labeling and marking must adhere to IS 8148:2018 guidelines. If the product conforms to IS 8148:2018 requirements, it may receive certification under the Bureau of Indian Standards Act, 2016, along with its relevant Rules and Regulations, and can be affixed with the Standard Mark (ISI Mark). Manufacturers are required to obtain a BIS license from the Bureau of Indian Standards to use the standard mark (ISI Mark), which is granted following a successful evaluation of manufacturing infrastructure, quality control, testing capabilities, and production processes.
