The following conditions shall be applied to the test medium: water shall have a temperature of(10士1) °C; the water pressure shall be (25土2) psi (1,72士0,14) bar. 5.7 General conditions for weight measurement General conditions for weight measurement shall be according to EN 4855-01. 6 Test procedures 6.1 General The purpose of this test is to measure the power demand of beverage maker products and the cycle time. The test is split into two parts: a) power measurement during one cycle of brewing (beverage maker) or tapping hot water (water heaters); b) steady state/stand-by power measurement. 6.2 Energy consumption test Two tests have to be performed consecutively described as follows: a] All environmental conditions have to be ensured during the whole test procedures. b) A warming plate, if available, shall be turned off. c] Before start of each test the EUT has to be installed as instructed in the manual and tanks, if available, shall be filled with water. d) The measurement equipment has to be installed. The logging has to be started before start of the test.BS EN 4855-04 pdf download.
