4 Identification number: PTB Ex PTS Date: Test sample number: PTB Ex PTS - PE Test: Program "Pressurized Enclosure - Test Round 2017" 4 - "Determination of worst case measuring point" Description: Instruction of program "Pressurized Enclosure - Test Round 2017", Chapter 4 Table 5: Position of "worst case" measuring point (MPworstcase CO2 ) for CO 2 x-axis [mm] y-axis [mm] z-axis [mm] Table 6: Position of "worst case" measuring point (MPworstcase He ) for He x-axis [mm] y-axis [mm] z-axis [mm] Table 7: Please describe why you have rated the noted measuring points as worst measuring points: e.g. For CO 2 : Purging time PC1 was not sufficient, gas concentration did not fall below limit at measuring point MPworstcase CO2, therefore did not pass e.g. For He: Test has been performed with own defined purging time of 10 min. Gas concentration did not fall below limit at measuring point MPworstcase He, therefore did not pass. e.g. highest gas concentration measured at MPworstcase CO2 /MPworstcase He, therefore considered as worst case measuring point e.g. no worst case measuring point was identified PTB Working Group Page 4 of 5
