This document specifies the test procedures and calculations to determine the ECO efficiency of the following catering equipment installed in an aircraft: chilling equipment (with and without freeze function); ovens (steam and convection ovens); beverage makers (coffee maker, water heater); trash compactors (single and double bin); espresso makers (grain, powder, pad and capsule based). Based on the results it will be possible to derive the energy consumption index and a performance index of the considered equipment type. The two index values represent the ECO efficiency.
