18. In the case of a refrigerating apparatus, the capacity is established in relation to the engine or engines which operate it with a service factor of 1:

(a)  in the case of a triphase electric motor, when the capacity is not established by the manufacturer, it is established by using one or the other of the following formulas which take into account a power factor of 90% and an efficiency of 80%:

i.  kW = 0.001 245 × E × I

where: E is the potential difference in volts; and I is the rated current in amperes;

ii.   kW = 0.80 × kWe

where: kWe is the rated number of kilowatts supplied at the intake;

iii.  kW = 0.72 × kVA

where: kVA is the rated number of kilovolt-amperes;

(b)  in the case of an internal combustion engine, when the capacity in kilowatts is not established by the manufacturer, it is established by multiplying by 0.046 the product of the square of the diameter of the cylinders in centimetres, by the number of cylinders.
