Legal Basis: Paragraph 4, Article 14 of the Energy Management Act
1. The low-voltage three-phase squirrel-cage induction motor (“induction motor” hereafter) set in this announcement covers goods in compliance with Clause 14400 of Chinese National Standards (CNS), with a rated output power from 0.75kW/1HP to 200kW/270HP or which are subjected to inspection by the Central Competent Authority.
2. The specific equipment mentioned in this announcement indicate pumps, air compressors or fans that include induction motors.
3. The energy efficiency labeling for the induction motors mentioned in the above two points, should be in compliance with regulations as in the Induction Motor IE2 Energy Efficiency Standards (See Appendix 1) or Induction Motor IE3 Energy Efficiency Standards (See Appendix 2).
4. Before making or importing the induction motor, the supplier shall apply for account ID and password to the Energy Efficiency Labeling Management System (“EELMS” hereafter) administered by the central competent authority (CCA) with the following documents:
(1) The EELMS account ID and password application form (Appendix 3).
(2) Copy of the company or commerce registration certificate.
5. Before making or importing the induction motor, with a rated output power greater than 74.6kW, the supplier shall apply for the induction motor's energy efficiency labeling with the EELM, administered by the CCA with the following documents:
(1) Original of the energy efficiency labeling for induction motor application form (Appendix 4).
(2) When applying for more than three type of registration for energy efficiency labeling for induction motors, the supplier shall provide hard or soft copy of the energy efficiency test report for the two designated types, and reports will be chopped with official company stamp.
(3) For suppliers that have entrusted the application to a third party, the original mandate of delegated power (Appendix 5) shall be included.
The energy efficiency test report mentioned above, shall be issued by certification authorities that are members of the mutual recognition agreement signed by the Taiwan Accreditation Foundation (“TAF” hereafter) and the International Laboratory Accreditation Cooperation (“ILAC” hereafter), laboratories certified by the Bureau of Standards, Metrology and Inspection, MoEA, Bureau of Energy, MoEA, etc., or by Underwriters Laboratories Inc. (“UL” hereafter) and Technischer Überwachungs-Verein (“TÜV” hereafter); the energy efficiency testing method used in the test reports shall conform to the active CNS 14400, the International Electrotechnical Commission (“IEC” hereafter) standard 60034-2-1 or the Institute of Electrical and Electronics Engineers (“IEEE” hereafter) standard 112B. Machines with the same type, number of poles and rated output power, shall be considered to be the same basic model induction motor.
6. Before making or importing the induction motor, with a rated output power lower than 74.6kW, the supplier shall apply for the induction motor's energy efficiency labeling (Appendix 4), and include the Certificate of the Registration of Product Certification issued by the Bureau of Standards, Metrology and Inspection, MoEA, according to IE2 energy efficiency standard of induction motors (Appendix 1) or IE3 energy efficiency standard of induction motors (Appendix 2), the original certificate will be color scanned into digital file and transmitted to the EELMS or sent the disk containing the file to the CCA.
7. The supplier shall apply for the induction motor's energy efficiency labeling again before making or importing it in case of the following:
(1) Design changes which may have impact on energy efficiency.
(2) Model changes.
(3) Amended regulation for IE2 energy efficiency standard of induction motors (Appendix 1) or IE3 energy efficiency standard of induction motors (Appendix 2).
Before making or importing the induction motor, if changes affect the contents detailed in the Certificate of the Registration of Product Certification, application for changes shall be submitted according to the regulations of Bureau of Standards, Metrology and Inspection, MoEA. The copy of changed Certificate of the Registration of Product Certification chopped with official company stamp shall be submitted to the CCA.
8. When displaying, selling, making or importing induction motors, the supplier shall attach the following items to the front and visible position of the machine:
(1) Name: Three-phase squirrel-cage high efficiency induction motor.
(2) Number of poles;
(3) Rated output power (kW or HP) ;
(4) Rated Voltage;
(5) Rated frequency;
(6) Symbol for the degree of protection by enclosure (IP code);
(7) Symbol of motor type;
(8) Year of manufacture;
(9) Manufacturer's name or trade mark.
(10) Efficiency at rated load( efficiency at full load);
(11) Type of efficiency (IE2 or IE3)
The above items shall all be labeled in Mandarin Chinese, except for unit symbols or special characters, and cannot be concealed, destroyed or rendered otherwise unrecognized.
9. From 1 July 2015, rated output power, number of poles or revolutions, rated voltage, rated frequency, IP code, full load efficiency and other energy efficiency related performance parameters shall be labeled on the induction motors installed in specific equipment or on visible positions on the machine.
10. The supplier shall report last year's unit sales of each model of the induction motor before the end of February each year.
11. The CCA may run annual random tests for energy efficiency checks, the supplier shall deliver units of models specified by the CCA to given labs before the given date; if values of the test outcome are not conform to the IE2 energy efficiency standard of induction motors (Appendix 1) or IE3 energy efficiency standard of induction motors (Appendix 2), the CCA shall call the supplier for another test, the second test shall be made against the same mode at twice the quantity given for the first one, and the supplier shall foot the bill of the second test. Supplier making or importing specific equipment shall comply with the CCA random tests on energy efficiency and labeling for induction motors, and provide relevant data.
12. The CCA shall subject suppliers who do not undergo the secondary test or who failed the secondary test to Clause 21 and 24 of the Energy Administration Act. This does not apply to the suppliers who do not undergo secondary test due to termination of production or import and have been approved by the CCA for revoking their induction motor's energy efficiency labeling.
13. Units of random test said in Item 11 shall be determined by the induction motors made or imported in the last year: test one for every 5000 units and on for less than 5000 units, test a maximum of 10 for each supplier. The CCA may revise test units as required.
