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.

4.—(1) To determine the minimum efficiency of 50 Hz motors with rated power outputs (PN) of between 0.12 and 200 kW not provided in Tables 21 to 26, the following formula must be used—
(2) For the purposes of paragraph (1), A, B, C and D are interpolation coefficients to be determined according to Tables 27 and 28.
(3) The minimum efficiency of a motor with a rated power output (P) between 0.55 kW and 0.75 kW must be calculated by linear interpolation from the obtained minimum efficiencies of a motor with a rated power output of 0.55 kW and a motor with a rated power output of 0.75 kW.
5. The minimum efficiency of 60 Hz motors at a rated power not provided in Tables 24 to 26 must be determined as follows—
(a)the efficiency of a rated power at, or above, the midpoint between two consecutive values in the tables is the highest of the two efficiencies;
(b)the efficiency of a rated power below the midpoint between two consecutive values in the tables is the lowest of the two efficiencies.
