Overview

EN 4855-02:2025 - Aerospace series: ECO efficiency of catering equipment - Part 02: Oven equipment (CEN) establishes a standardized test procedure and calculation method to quantify the ECO efficiency of convection and steam ovens used on aircraft. The standard defines how to measure warm-up time, electrical energy use during pull-up and standby, and equipment weight, and it converts these measurements into two dimensionless indices: an Energy Consumption Index (ECI) and a Performance Index (PI). EN 4855-02:2025 supersedes EN 4855-02:2020 and is intended to support consistent energy-efficiency assessment across aerospace oven equipment.

Key topics and technical requirements

  • Test scope: Convection and steam ovens installed in aircraft galleys; includes load cases for standard meal capacities (e.g., 32 and 48 meals).
  • Test medium: Standard water‑soaked thermal bricks (67 × 125 × 37 mm); selected bricks drilled to accept thermocouples; soak for ≥8 h and pre-test temperature (5 ± 2) °C.
  • Measured parameters:
    • Warm‑up time: time for all test media to reach 71 °C.
    • Electrical energy during pull‑up plus 0.067 h (4 min) heating.
    • Standby power after 0.083 h (5 min) at steady state.
    • Operational (installed) weight of the oven.
  • Index calculations:
    • Kerosene-equivalent consumption is derived from electrical consumption during pull-up, standby power and oven operational weight, then scaled per test medium.
    • ECI expresses scaled kerosene consumption relative to a reference value (mK,ref = 0.155 kg per meal) as a percentage.
    • PI compares the oven warm‑up time to a reference warm‑up time (Tref = 0.39 h) and reference number of test media (Nref = 32) to yield a dimensionless performance score.
  • Test environment and instrumentation: Environmental conditions, power supply and measurement equipment follow EN 4855-01:2025 and referenced international methods (EN IEC 60350-1).

Applications and who uses it

  • Aircraft OEMs and galley equipment designers: to benchmark and optimize oven designs for in-flight energy efficiency.
  • Airlines and procurement teams: to compare oven models on a consistent ECO efficiency basis for fleet selection.
  • Test laboratories and certification bodies: to perform repeatable efficiency testing, produce compliant test reports and calculation sheets.
  • Environmental and sustainability teams: to estimate onboard fuel-equivalent energy use per meal and support carbon-reduction programs.

Introduction
During aircraft operations, the food preparation in the cabin is mandatory to maintain the catering on
board. There exist different equipment types to heat up the prepared meals for the passengers in the
cabin. On the one hand meals can be heated by usage of steam (steam ovens); on the other hand it can
be heated by usage of hot and dry air (convection oven). To meet the target to determine an energy
efficiency index for aircraft oven equipment, the purpose of this document is to standardize the test
procedure and efficiency calculations for this equipment type.
1 Scope
This document specifies a test procedure to identify performance characteristics and a weight rating of
convection and steam ovens used on aircraft. Furthermore, it specifies the calculation procedure to
determine an energy consumption index and a performance index. There is no direct correlation
between the ECO efficiency and cooking performance in terms of food quality and appearance. The two
index values represent the ECO efficiency.
