Abstract:
A new En score of the proficiency test (PT) is formulated; it is applicable when a correlation exists between the reference and participant’s values. Based on the uncertainty propagation rule given in ISO/IEC Guide 98-3 (GUM:1995), the En score covering the correlation case is newly developed for the PT. The new En score will be applied in a future PT organized by the Korea Research Institute of Standards and Science (KRISS) dosimetry team. The new En score will enhance measurement traceability and contribute to improving the quality management system of participants in the KRISS PT by avoiding performance underestimation.
