Introduction

Proficiency testing is the use of inter-laboratory comparisons to evaluate participants' abilities in accordance with pre-established criteria: Participating in proficiency testing is a laboratory an important means of quality assurance, helps the laboratory evaluate and prove the reliability of its measurement results, discover its own problems, and improve the laboratory Technical ability and management level: The results of the proficiency test can be used as an effective proof of the laboratory's technical capabilities, for the management department, customers and Provide basis for selection, evaluation and accreditation of competent laboratories by other stakeholders:

As the main body to participate in proficiency testing, laboratories should comprehensively consider internal quality control based on their own needs and external requirements for proficiency testing:

Based on factors such as level, personnel capabilities, equipment conditions, risks, and operating costs, rationally plan and actively seek appropriate proficiency verification plans:

In addition to the proficiency testing programs organized by recognized proficiency testing providers (PTP), there are a large number of industries Organizational operation proficiency testing plan: For the proficiency testing program carried out by the accredited PTP within its accreditation scope, the laboratory can Choose to participate and directly use the proficiency test results: For other proficiency testing programs, laboratories can refer to this standard to verify them to Confirm whether it meets the requirements:
