6  Equation 18—determining the high efficiency threshold for the fan (𝜂HE,i)
  The high efficiency threshold of a particular fan i, 𝜂HE,i, is worked out using the equation (equation 18):
  where, for fan i:
ai is a regression coefficient, and is determined in accordance with Schedule 4.
ln(PE,i­) is the natural log of the motor input power (PE,i), in kilowatts, of the fan, where PE,i has the same meaning as in section 5 of this Schedule.
bi is a regression constant, and is determined in accordance with in Schedule 4.
NHE,i is the high efficiency grade of the fan, and is determined in accordance with Schedule 5.
