Verification Testing

 

NEA will from time to time carry out verification testing (VT) on registered models. All VTs will be carried out in accordance with the applicable test standards.

The report for the 2024/2025 VT can be found here. [PDF, 314kB]

Conformance

A registered model is deemed to have passed the VT if the energy performance obtained through VT falls within the conformance limits specified in the tables below:

Table 1: VT conformance limits

Regulated GoodsLimit
Air-conditioner (including single-phase Portable Air-Conditioner)COP computed from results of VT > 0.9 x COP computed from Test Report data
RefrigeratorEnergy consumption computed from results of VT < 1.10 x Energy consumption computed from Test Report data
Clothes DryerEnergy consumption computed from results of VT < 1.10 x Energy consumption computed from Test Report data
Television 
Energy consumption computed from results of VT < 1.10 x Energy consumption computed from Test Report data
Lamp
Refer to compliance conditions for lamps in Test Report section
Water HeaterEnergy consumption computed from results of VT < 1.10 x Energy consumption computed from Test Report data
Three-Phase VRF Air-Conditioner
COP computed from results of VT > 0.9 x COP computed from Test Report data (i.e. COP for 100%, 75%, 50% and 25% loading).
Three-Phase Induction Motor 
(a) For motors with rated output power of up to 150kW
(100% - motor efficiency at rated output power) from results of VT ≤ 1.15 times of (100% - Minimum Efficiency at the rated output power for the respective IE classes)

(b) For motors with rated output power of above 150kW
(100% - motor efficiency at rated output power) from results of VT ≤ 1.10 times of (100% - Minimum Efficiency at the rated output power for the respective IE classes)
Commercial Storage RefrigeratorEnergy consumption computed from results of VT < 1.10 x Energy Consumption computed from Test Report data
