Overview

EN 4855-06:2025 - "Aerospace series - ECO efficiency of catering equipment - Part 06: Espresso maker" (CEN) defines a standardized test method and calculation procedure to quantify energy use and operational performance of espresso makers installed on commercial aircraft. The standard produces two key, comparable metrics: an Energy Consumption Index (ECI) and a Performance Index (PI). Note: espresso sensory quality (taste/quality) is explicitly outside the scope.

Key topics and technical requirements

• Test purpose: Measure power demand during initial heating, steady‑state, and brewing to derive energy/performance indices.
• Test conditions: Environmental, power supply, measurement equipment and test setup are aligned with EN 4855-01:2025 (general conditions).
• Test media and settings:
  • Potable water at (15 ± 1) °C and water pressure (25 ± 2) psi (≈1.72 ± 0.14 bar).
  • Espresso brew volume defined as 25 ml to 40 ml.
• Measurement sequence:
  • Record energy during initial heating and during a 1 h steady‑state period.
  • Perform 20 consecutive brews (replace coffee medium per manufacturer) to measure average cycle time and average energy per brew.
  • Deactivate non‑brewing functions (e.g., warming plates) during testing.
• Outputs and calculations:
  • Average steady‑state power and energy per brew (kVA, kVAh) are recorded.
  • The standard prescribes calculation of a scaled kerosene-equivalent consumption per espresso and the dimensionless ECI relative to a reference (reference kerosene consumption = 0.112 kg/espresso).
  • The PI compares measured average cycle time to a reference cycle time (reference t_E,ref = 0.00950 h).
• Reporting: Test data and calculated indices are documented on a calculation sheet per EN 4855-01.

Applications and who uses it

• Aircraft manufacturers (OEMs) and galley designers - to evaluate and compare espresso makers for new aircraft installations.
• In-flight catering equipment suppliers and product engineers - to optimize design for lower energy use and faster cycle times.
• Test laboratories and certification bodies - to provide repeatable, comparable energy and performance data for procurement and compliance.
• Airline sustainability and procurement teams - to benchmark equipment energy performance (ECI) and operational productivity (PI) when selecting galley appliances.

Related standards

• EN 4855-01:2025 - Aerospace series - ECO efficiency of catering equipment - Part 01: General conditions (normative reference for environmental, measurement and calculation rules).
• EN 4855 series - other parts addressing different galley appliances and the common ECO efficiency framework.
