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 exper,ience and the accuracy needs ot this
program.
, -
,
In these criteria, the judgment limits are variable in relation to the com-
parison 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 to
maintain statistical consistency with the number of significant figures reported
by the NRC Reference Laboratory, unlE5s such rounding yill result in a narrowed
category of acceptance.

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.
