For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
ISO Online browsing platform: available at http://www.iso.org/obp
IEC Electropedia: available at http://www.electropedia.org/
3.1
catering equipment
equipment installed in an aircraft to provide or support food or beverage service
Note 1 to entry: Includes ovens, beverage makers, water heaters and chilling equipment.
3.2
electrical energy consumption
measured apparent power integrated over a period of time
3.3
ECO efficiency
aspect of sustainability of catering equipment regarding the energy consumption and performance
during aircraft operation
Note 1 to entry: ECO efficiency in this context does not consider the whole life cycle assessment of catering
equipment.
3.4
energy consumption index
ECI index (dimensionless) describing the energy consumption related to a reference equipment during operation
3.5
performance index
PI
index (dimensionless) describing the performance related to a reference
Note 1 to entry: The definition of the performance index is specific for each equipment type, see in EN 4855-02,
EN 4855-03 and EN 4855-04.
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.
5.4 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.BS EN 4855‑01 pdf download.
