September 3, 2013

Abstract

In the past, the proficiency testing items and participation frequency were formulated by accreditation bodies, regardless of the scale, customer type, and economic conditions of a laboratory. In 2010, ILAC P9 require the applicant laboratories considering needs and risk level to make their own proficiency testing participation plan , as long as proficiency testing program feasible both logistically and economically. In response to the requirements of ILAC P9, Taiwan Accreditation Foundation (TAF) revised the accreditation criteria document-- Requirements for proficiency testing activities. Submit a PT plan prepared by the laboratory seeking for accreditation is required in this revised document. To facilitate applicants to learn how to make a plan and implement thereafter, a guideline was developed by TAF based on the concept of risk evaluation. This paper will describe how to use qualitative risk analysis methodology to analyze the risk level of the factors affecting correctness/reliability of measurement results. The determining factors include experience, competence and turnover rate of staff, traceability sources, stability of measurement technique, number of tests, and significance and final use of the testing data, as mentioned in EA-4/18.
