If one brew cycle provides 1,5 l, 3 consecutive cycles shall be performed. The energy consumption and the duration for one cycle shall be recorded. The duration to achieve this amount of hot water shall be recorded. The temperature of the hot water shall never decrease below 70 °C. The temperature shall be measured at the water outlet. For water heaters: While tapping at least 4,5 l hot water, the energy consumption and the duration for this cycle shall be measured. The temperature of the hot water shall never decrease below 70 °C. The temperature shall be measured at the water outlet.The following information shall be given in a test report: a) type of equipment incl. equipment PN and SN; b) empty weight;
c) energy consumption; d) duration to brewing/tapping 4,5 l hot water; e) environmental temperature; f) conformity check.BS EN 4855-04 pdf download.
