European foreword
This document (prEN 4855-04:2024) has been prepared by the Aerospace and Defence Industries
Association of Europe — Standardization (ASD-STAN).
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 4855-04:2020.
The main changes compared to the previous edition are as follows:
— change of test medium water temperature in 5.6 from 10 °C to 15 °C in to allow easier setup and
continuity of water temperature;
— changes and clarification of coffee maker and water heater operation and measurements;
— clarification of water tapping for water heater in 6.2.3 b) in case of temperature drop below 80 °C;
— updated values for scaled reference kerosene consumption for beverage maker and for water heater
in 7.2;
— updated values for reference cycle time for beverage maker and for water heater in 7.3.
Introduction
During aircraft operations the preparation of drinks in the cabin is mandatory to maintain the catering
on board during flight. There exist different equipment types to prepare different kinds of drinks. While
beverage makers are used as equipment to prepare coffee and tea, water heaters are used to tap hot
water for other use. To meet the target to determine an energy consumption index for aircraft beverage
maker products 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
beverage maker products used on aircraft. Furthermore it specifies the calculation procedure to
determine an energy consumption index and a performance index. The effect of the beverage makers on
beverage quality is not addressed in this document.
