Precision on aqueous calibration verification materials was estimated using four
850 systems. As many as seven runs per instrument were made over seven days.
Two replicates of each control level were analyzed in each run.
Table E-15 summarizes the results of the 850 system precision for CVM levels 1
and 4.
