8.2.6.2EUT using consumables
ForEUT using paper consumables, a 60 g/m2 to 80 g/m2 A4 paper with water content between 3,8% and5,6%，and printing the patterns as specified in A.1 and A.2 are appropriate for the following preparatoryoperation.The maximum duration of the operating phase shall be determined. Thereafter,lightness (L*) andcolour values (L’ , a , b*), as appropriate shall be determined from the printouts according to ClE 15:2004 andlSO 13655.
Before testing the EUT may be used up to the duration of the MUT. The MUT(as duration of the totaloperating cycles) is 120 minutes.
One to two 10-minutes operating cycles outside or inside the ETC shall be performed at least one day beforethe UFP test in order to determine the print speed, to ensure the proper operation and to avoid influence onemissions due to unstable UFP emission which sometimes may occur in operation after long-term disuse ofthe EUT.
For the RAL-UZ 171 option one or two 10-minute operating cycles or at most 1000 printed pages areacceptable for the purpose of EUT function testing and measuring of print speed and no further preparationand/or usage shall be executed unless required due to malfunction of the EUT.
Treatment conditions shall be recorded in the test report.
8.2.7EUT 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 suitabletest 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 alloperators 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 paperconsumables,60 g/m2 to 80 g/m2 A4 paper with water content from 3,8% to 5,6% shall be used.
To avoid contamination, the powered-off EUT shall be installed in the middle of the ETC as fast as possibleand all operators shall leave the ETC immediately thereafter.
The EUT shall remain powered-off until the emission test as specified in 8.2.8，requires the EUT to bepowered-on.
For the determination of FP and UFP specified in 8.6 and/or for the RAL-UZ 171 option the EUT shallbe installed on the day before the emission test.
The ETC shall remain closed until all sampling and or monitoring is completed.
The installation date and time shall be recorded.
Emission testing, as specified in 8.2.6, shall not begin within at least 3 air exchanges following installation.
8.2.8 EUT operation during test
8.2.8.1 Recording of EUT operation
The start of the operation of the EUT shall be recorded as the time t 0.
The start and duration of the operating phases shall be recorded.
8.2.8.2 EUT not using consumables
For this class of EUT, VOC and carbonyl compounds shall be determined as specified in 8.3 and ozone should be determined as specified in 8.4 while continuing to execute its intended functions as initiated during installation (see 8.2.7.1).
The used test standard or specification shall be reported, preferably by referring to a standard.
8.2.8.3 EUT using consumables
8.2.8.3.1 General For this class of EUT, VOC and carbonyl compounds as specified in 8.3; ozone as specified in 8.4; particulate matter as specified in 8.5 and FP and UFP as specified in 8.6 shall be determined while the EUT being controlled from outside the ETC.BS ISO IEC 28360 pdf download.
