identical text or by endorsement, at the latest by August 2020, and conflicting national standards shall
be withdrawn at the latest by August 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,

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 standardise the test procedures and
calculations to determine the ECO efficiency for catering equipment installed in the aircraft.
1 Scope
This document defines the test procedures and calculations to determine the ECO efficiency of the
following catering equipment installed in an aircraft:
 Chilling equipment (with freeze function);
 Ovens (steam and convection ovens);
 Beverage makers (coffee maker, water heater).
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 defined in the following.
The EUT shall not be used for at least 2 h before start of each test and it shall be ensured that the
environmental temperature 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 according to the following procedures:
a) measurement for ovens according to EN 4855-02;
b) measurement for chilling equipment according to EN 4855-03;
c) measurement for beverage makers according to EN 4855-04.
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 during the whole
test run 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 respective manufacturers’ ICD
of the EUT PN. The rated voltage shall be (115 ± 2) VAC on each of the three phases. The frequency
during test shall be set to (400 ± 5) Hz.
5.4 Measurement equipment
A device to measure the temperature shall be provided.
All measurement equipment shall be calibrated.
All temperature measurement equipment shall have a maximum measuring tolerance of ±0,5 K. Table 1
shows the required equipment.
For convenience all terms of “power” related to electrical power measurements, in this document and in
EN 4855-02, EN 4855-03 and EN 4855-04, the term of “apparent power” shall be applied.

Power measurement ±1 %
Datalogger N/A
Weight scale ±0,01 kg
Time measurement ±0,5 s
5.5 General weight measurement conditions
For all EUT the empty weight in [kg] has to be determined.
Any insert, which does not belong to the equipment PN, shall be removed (e. g. server, oven racks etc.).
EUT shall be completely drained.
5.6 Noise measurement
The sound power shall be measured in A-weighted octave bands and calculated as described in
EN ISO 3744:2010, Clause 8 and E.1. A test setup with nine microphones as described in Figure C.7 shall
be used for the test.
NOTE 1 The test can be performed without the corner microphone positions 5 to 8 (according to
EN ISO 3744:2010, Figure C.7).
NOTE 2 The noise measurement for beverage makers is not necessary.
