European foreword
This document (EN 4855-03:2025) has been prepared by ASD-STAN.
After enquiries and votes carried out in accordance with the rules of this Association, this document has
received the approval of the National Associations and the Official Services of the member countries of
ASD-STAN, prior to its presentation to CEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by April 2026, and conflicting national standards shall be
withdrawn at the latest by April 2026.
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.
This document supersedes EN 4855-03:2020.
This document includes the following significant technical changes with respect to EN 4855-03:2020:
— removed “Only galley chilling equipment with a freeze function will be considered” from the scope;
— correction of the formula for the kerosene consumption due to the correction of the formula in
EN 4855-01;
— removed “For this energy consumption index, only equipment with a freeze function will be
considered.” from note in 3.2;
— added measurement of the storage volume to 5.1;
— clarified test medium in 5.6;
— rewritten operating conditions to allow for units without freeze mode in 5.8;
— reduced total amount of storage capacity filled by test medium in 6.1 from 100 % of storage volume
to 30 % allowing for air to circulate between test media and provide for realistic load situation;
— swapped 6.2 and 6.3;
— clarified the specification of end of pull-down time in 6.3;
— specification of usable inner volume according to actual volume rather than number of media
insertable in 7.2;
— reestablishment of reference values required due to procedure changes;
— updated values for scaled reference kerosene consumption in 7.2;
— updated values for reference inner equipment volume and reference pull-down time in 7.3.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,

Introduction
During aircraft operations the food storage in the cabin is mandatory to maintain the catering on board.
There exist different equipment types to cool, freeze or chill any food or drinks. To meet the target to
determine an energy efficiency index for galley chilling equipment (freezers, refrigerators and beverage
chillers) the purpose of this document is to standardize the test procedure and efficiency calculations
for this equipment.
1 Scope
This document specifies a test procedure to identify performance characteristics and a weight rating of
a galley chilling equipment used on aircraft. Furthermore, it specifies the calculation procedure to
determine an energy consumption index and a performance index. The effect of the chilling equipment
on food quality is not addressed in this document.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.
