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.
In July 2014, NEA completed the first VT exercise on a selection of air-conditioner, refrigerator and clothes dryer models registered under MELS. Overall, all models tested were assessed to have passed the VT. A report summarizing the results can be found here [PDF, 471.25 KB]
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 Goods | Limit |
| Air-conditioner (including single-phase Portable Air-Conditioner) | COP computed from results of VT > 0.9 x COP computed from Test Report data
|
| Refrigerator | Energy consumption computed from results of VT < 1.10 x Energy consumption computed from Test Report data |
| Clothes Dryer | Energy 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
|
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)
