BS EN 4855-03 1 Scope This European standard describes a test procedure to identify performance characteristics and a weight rating of a galley chilling equipment used on aircraft. Furthermore it describes the calculation procedure to determine an energy consumption index and a performance index. Only galley chilling equipment with a freeze function will be considered. The effect of the chilling equipment on food quality is not addressed in this standard. 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.

EN 4855-01, Aerospace series一ECO efficiency of catering equipment一Part 1: General conditions 1  EN 62552, Household refrigerating appliances 一Characteristics and test methodsThe test conditions described in EN 4855-01 shall be ensured before start of the test run. The purpose of this test is to measure the power demand of the galley chilling equipment.The duration of one test is 3 h. It shall be ensured that the door of the EUT is closed during the whole test run.  a) The test starts after loading the EUT with the test media and closing of the front door. The logging shall be started and the power shall be recorded over the whole test duration. The measured power has to be integrated over the test duration for energy consumption calculation. The energy consumption shall be given in kVAh. b] The temperature of the EUT has to be set as given in 5.8. c) The duration of the Pull-Down-Time shall be noted as follows: For freezers, the Pull-Down-Time after cooling down by 10 K shall be noted. d) The following results shall be noted: 1) energy consumption after 60 min (EB,p); 2]) average steady state power (Ps,F) between 60 min and 180 min. After 180 min test duration the logging has to be stopped and the EUT shall be turned off. AIll test media shall be taken out from the EUT. BS EN 4855-03 pdf download.
