Article 22

22.1 For any vehicle which does not meet the Energy Efficiency Standards in respect to the results

of the conformity test provided in Article 4, Article 5 and Article 6, the entity who applied for the

type approval test may apply for a retest. The retest shall be performed according to the following

procedures:

22.1.1 The results of three retests for the original sample test vehicle shall be averaged to a single

value (hereinafter referred to Y).

22.1.2 Y and all of the one-time retest results for each vehicle requested for retesting by the

application entity and selected by the Competent Authority shall be averaged to determine a single

value (hereinafter referred to X).

22.1.3 In the event that the difference of X and the product of statistical parameter times the

standard deviation is not smaller than the Energy Efficiency Standards, the vehicles covered by the

application shall be regarded as meeting the Energy Efficiency Standards. The standard deviation is

calculated by the following equation:

                                     ┌─────────────────

                                     │                                                     2  

Standard Deviation =   │       (energy efficiency Value - X)   

                                     │Σ ─────────────── 

                                     │    Number of Sample Vehicles - 1 

                                     │                                  

                                     ˇ                                   

The statistical parameters are to be determined based on the number of sample test vehicles, as in

the following table:

If the number of sample test vehicles is equal to or greater than 20, then

                                                           0.860              

Statistical Parameter = ───────────────

                                       ┌─────────────

                                       │ Number of Sample Vehicles

                                       ˇ                           

22.2 In the event that the entity does not apply for retesting, or the results of the retesting do not

meet the Energy Efficiency Standards under this Article, the certificate of conformity in respect to

the vehicle or the model of vehicle covered by the certificate shall be annulled. The Competent

Authority shall forthwith withhold from the entity the right to sell the vehicles and order the entity

to take actions to improve the energy efficiency of the vehicles. The Transportation Management

Authority shall not issue vehicle licenses to the vehicles of the model concerned or to any entity

who commits a breach of Article 18 as well.

22.3 The entity applying for a retest as described in Paragraph 22.1 of this Article shall deliver the

vehicles to the Accredited Agency appointed by the Competent Authority.

Article 23

23.1 If the conformity test results for the domestic-manufactured or imported vehicles in accordance

23.2 The Competent Authority officers should be accompanied by the personnel of the Accredited 

Agency to the vehicle storage location, and pick up at least twice the number of the previous 

sampled vehicle type that failed to reach within 92% of the energy efficiency label value. The 

selected vehicles should be delivered to the Accredited Agency by the vehicle entity to perform the 

energy efficiency retest.

23.3According to Article 21 of Energy Management Act, should the vehicle entities failed to meet 

the deadline to perform energy efficiency retests or the mean value of the test results for the 

delivered sample vehicles failed to reach within 92% energy efficiency label value will be notified 

by the Competent Authority for improvements.
