In current technological research and laboratory testing, quality management is crucial to ensuring the reliability of test data, the accuracy of test results, and the repeatability of tests. In order to improve the quality management level of testing laboratories, various quality management system certifications such as CNAS (China National Accreditation Service for Conformity Assessment) and CMA (China Inspection Body and Laboratory Mandatory Approval) have been widely used in laboratories through certification and review processes. The laboratory extensively employs the PDCA cycle (Plan-Do-Check-Act) in quality management. This article explores the application of the PDCA cycle in quality management of testing laboratories and its benefits to laboratory quality management.
