Introduction
Efficient and economic aircraft operation is one of the main objectives in the aviation industry. The main
goals for a competitive and environmental friendly operation are to reduce weight, fuel consumptions
and thus to lower the costs leading to a more sustainable aircraft.
Today’s aviation industry standards do not provide a classification of catering equipment according to
their power demand and weight. Since it is state of the art for household appliances to be rated with ECO-
label categories, the purpose of this document is to standardize the test procedures and calculations to
determine the ECO efficiency for catering equipment installed in the aircraft.
1 Scope
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 makers, water heaters);
— 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.

5 General test conditions
5.1 General
Measurement conditions and calculation formulas are specified in the following subclauses.
To minimize rounding effects on the calculation results, all values related to measured or calculated
weights shall have two decimals and all values related to measured and calculated power / power
consumption shall have three decimals.
The EUT shall not be used for at least 2 h before start of each test and during which it shall be ensured
that the environmental temperature in accordance with 5.2 is maintained in the entire EUT (e.g. inner
cavity or tank).
All test results shall be recorded in a test report.
Equipment tests to derive the ECO efficiency shall be performed in accordance with the following
procedures:
a) measurement for ovens in accordance with EN 4855-02;
b) measurement for chilling equipment in accordance with EN 4855-03;
c) measurement for beverage makers in accordance with EN 4855-04;
d) measurement for trash compactors in accordance with EN 4855-05;
e) measurement for espresso makers in accordance with EN 4855-06.
5.2 Environmental conditions
All tests shall be performed in a room with a maximum air speed of 0,2 m/s.
The ambient temperature shall be (24 ± 3) °C. The ambient temperature shall be held from 2 h before
the test until the end of the test and shall not be influenced by the EUT or other equipment.
The ambient temperature and air flow shall be measured at a distance between 0,5 m and 2 m from each
equipment.
The ambient temperature measurement shall be started directly before test start. The sample time of the
temperature measurement shall be set to at least 0,5 Hz.
The tests shall be performed at an ambient pressure level of (1 013,25 ± 50) hPa.
5.3 Power supply and voltage
Each equipment under test (EUT) shall be connected as instructed by the
