| Attached are the five zone particle measurements for the clean room now that the fan speeds have been set to MEDIUM. 2 min sample time, 3 samples per zone. The occupied clean room measurements were unusual in that they generally got larger towards minute 6 instead of settling and going to zero, and for this reason didn't stay beneath the class 5 requirement at the end of the samples. The unoccupied counts look more similar to what was expected, and generally settle under the class five requirement. |
