and are not continuous assumptions must be made for the dewpoints trends between readings.

1.

For the purposes of this analysis, it is assumed that when the dewpoint rises to an out of specification high level following an in-specification reading, that this occurrs immediately after the last in specification reading. Conversely when an in specification value follows an out of specification high dewpoint, it is assumed that the dewpoint falls to the in-specification level just prior to the in-specification reading.

2. It is assumed that when theoretically impossible readings are obtained, the quality is indeterminate.

3.

It is assumed that in the absence of actual readings or when the when the dewpoints are indeterminant, and dryers are experiencing performance problems or are out of service, that dewpoints are out of specification high.
