Verification & Challenge Testingg g

Verification of Label Data by BEE using two samples. y g pOne from Manufacturer’s facility and one from retail. Samples selected sealed and shipped to independent NABL accredited test facility.yChallenge test can be initiated by any person. If BEE is satisfied by the request, the samples are picked up and tested as aboveand tested as above. Failure leads to an optional re-test with twice the no. of samples. Repeat failure leads to re-classification. Manufacturer liable for correcting the label orManufacturer liable for correcting the label orremoving the defect/deficiency for new products as well as products for sale in market.

Open Issues p

The Capacity rating test conditions require a review to p y g qfactor higher ambient temperatures in North & Central India

ISO5151 T3 condition is an optionpAlternatively a study of Weather data of India may suggest a unique condition for incorporation into the Standards

Max Operating Test Conditions require a review. p g qIS1391specifies 35/24oC for Room Temp & 46/27oC for Outdoor. Weather data suggests need for review

Test Voltage 230V-1Ph-50Hz is specified for IndianTest Voltage 230V 1Ph 50Hz is specified for Indian Standards. Products optimized for 220V or 240V may not deliver comparable energy efficiency at 230V

Definition of TermsTested Energy Consumption (Et) This is calculated for a period of 24 hours. (Units: Wh)This is calculated for a period of 24 hours. (Units: Wh)

Projected Annual Energy Consumption (PAEC) The estimated energy used by a single unit during one year’s use. This is calculated from Tested Energy Consumption (Et) (Units: kWh/Year)Tested Energy Consumption (Et) (Units: kWh/Year)

Comparative Energy Consumption (CEC) The nominal energy consumption of a model of refrigerating appliance. It is based on the PAECav of the model. The CEC appears on the energy label. (Units: kWh/Year)

Total Adjusted Storage Volume for No Frost (Vadj_tot_nf) The rated storage volume of a compartment adjusted to compensate for heat loadings onThe rated storage volume of a compartment adjusted to compensate for heat loadings on spaces which are at temperature other than that of fresh food type space. The adjusted volume shall be calculated on the basis of the STORAGE VOLUME of each compartment.
