| 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.
| |
| t
| |
| 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.
