8.2.6.2 EUT using consumables For EUT using paper consumables, a 60 g/m 2 to 80 g/m 2 A4 paper with water content between 3,8% and 5,6%, and printing the patterns as specified in A.1 and A.2 are appropriate for the following preparatory operation. The maximum duration of the operating phase shall be determined. Thereafter, lightness (L*) and colour values (L*, a*, b*), as appropriate shall be determined from the printouts according to CIE 15:2004 and ISO 13655. Before testing the EUT may be used up to the duration of the MUT. The MUT (as duration of the total operating cycles) is 120 minutes. One to two 10-minutes operating cycles outside or inside the ETC shall be performed at least one day before the UFP test in order to determine the print speed, to ensure the proper operation and to avoid influence on emissions due to unstable UFP emission which sometimes may occur in operation after long-term disuse of the EUT. For the RAL-UZ 171 option one or two 10-minute operating cycles or at most 1000 printed pages are acceptable for the purpose of EUT function testing and measuring of print speed and no further preparation and/or usage shall be executed unless required due to malfunction of the EUT. Treatment conditions shall be recorded in the test report. 8.2.7 EUT installation 8.2.7.1 EUT not using consumables The EUT shall be installed while executing its intended function(s) as specified in ECMA-74, using suitable test signals as specified in chapter 5.2 of EN 55013:2013 or another appropriate standard or specification. To avoid contamination, the EUT shall be installed in the middle of the ETC as fast as possible and all operators shall leave the ETC immediately thereafter. 8.2.7.2 EUT using consumables Before installation, the EUT shall have sufficient consumables to complete the operations. In case of paper consumables, 60 g/m 2 to 80 g/m 2 A4 paper with water content from 3,8% to 5,6% shall be used.
