ATTACHMENT 1
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 variable in relation to the comparison
of the NRC's value to its associated one sigma uncertainty.
As that ratio,
referred to in this prograra 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
criteria and identified on the data sheet.
