3.—(1) IE is set out in Tables 21 to 26, for different values of the motor rated output power PN at 50 Hz or 60 Hz.
(2) IE classes are determined at rated output power (PN), rated voltage (UN), and based on 25 °C ambient reference temperature.
(3) For 50/60 Hz motors, the requirements in Tables 21 to 26 must be met at both 50Hz and 60 Hz at the rated output power specified for 50 Hz.
(4) For 50Hz motors the requirements in Tables 21 to 23 must be met at 50 Hz at the rated output power specified for 50 Hz.
(5) For 60Hz motors the requirements in Tables 24 to 26 must be met at 60 Hz at the rated output power specified for 60 Hz.
(6) Losses must be determined in accordance with Schedule 17.
