i CRITERIA FOR COMPARING ANALYTICAL MEASUREMENTS
'
This attachment provides criteria for comparing results of capability tests and verification measurements.
The criteria are based on an empirical relationship which combines prior experience and the accuracy needs of this
'
program.
In these criteria, the judgment limits are va table in relation to the comparison of the NRC's value to its associated one sigma uncertainty. As that ratio, referred to in this program as " Resolution", increases, the acceptability of a licensee's measurement should be more selective.
Conversely, poorer agreement should be considered acceptable as the resolution decreases.
The values in the ratio criteria may be rounded to fewer significant figures reported by the NRC Reference Laboratory, unless such rounding will result in a narrowed category of acceptance.
<
RESOLUTION RATIO = LICENSEE VALUE/NRC REFERENCE VALUE

Some discrepancies may result from the use of different equipment, techniques,
'
!
and for some specific nuclides.
These may be factored into the acceptance l
criteria and identified on the data sheet.
