Report Requirements
Fed Std ft
3
This report requires a minimum of 2 locations be measured, at least 1
sample be taken per location and at least 5 samples total be taken in
each cleanroom at a minimum sample volume of 0.1 cubic feet.
The 95% Upper Confidence Limit (UCL) will be calculated by the
HANDHELD if the number of sampled locations is equal to or less
than 9.
Air flow (Unidirectional vs. Non-unidirectional) will have an effect on
the minimum locations and minimum samples required. In general, the
Non-unidirectional option requires more of both locations and samples.
For the Fed Std ft
3
report, the classification for a particle size is based
on its samples taken from all locations in the cleanroom. Each particle
size is given one of the following results:
• a classification rating which will be one of the possible
classifications (1, 10, 100, 1000, 10000, 100000)
• “Unable to Classify” if it fails one of the above requirements
• an “Out of Range” if the calculated classification at that particle
count exceeds 100,000
ISO 14644-1
The ISO14644-1 standard requires a minimum of 60 second Sample
Time for each sample recorded.
Note:
The EU GMP 2009
report is only valid if the
instrument is configured with
the 0.5 and 5.0 micron
channel sizes.
EU GMP 2009
The EU GMP Standard Report requires that the unit has the channel
sizes 0.5μ and 5.0μ as these are the only channels that apply to this
standard.
The EU GMP Report has different concentration limits for cleanroom
status “At Rest” versus “In Operation”. When the cleanroom is “In
Operation”, Class D is not available. The standard is not defined for
Class D in an operational cleanroom.
