21  High efficiency level
 (1) A motor covered by this Determination meets the high efficiency level if its efficiency at 75 per cent or 100 per cent of rated load is not less than:
 (a) for a motor with a rated output power specified in Table 2 in Schedule 1—the minimum efficiency specified in the table for the type of motor; and
 (b) for a motor with a rated output power in between the values specified in Table 2—the value determined in accordance with the method specified in clause 5.4.5 or 5.4.6, as appropriate, of IEC 60034-30-1 Ed. 1.0.
Note 1: Clause 5.4.5 of IEC 60034-30-1 Ed. 1.0 deals with Interpolation of nominal efficiency limits of intermediate rated powers for 50 Hz mains supply frequency.
Note 2: Clause 5.4.6 of IEC 60034-30-1 Ed. 1.0 deals with Interpolation of nominal efficiency limits of intermediate rated powers for 60 Hz mains supply frequency.
 (2) A motor may be designated as "high efficiency" only if it meets the high efficiency level.
 (3) For subsection (1), the types of motor are:
 (a) 50 Hz and 60 Hz; and
 (b) 2‑pole, 4‑pole, 6‑pole and 8‑pole.
