Proficiency testing is to evaluate the testing process and results of the participating laboratories according to the relevant standards through the comparison between laboratories.It is a tool to improve the reporting reliability of third-party testing institutions.Proficiency testing is a part of evaluating the quality level of the laboratory,which can establish a system to test the ability level of projects within and between laboratories.Proficiency testing can also iden-tify problematic laboratory testing procedures and help third-party laboratories initiate improvement measures.In order to understand the testing ability of relevant enterprises in the determination of plastic tensile properties,the organiza-tion organized and implemented the project CVC2023PM02 plastic tensile property testing proficiency testing scheme in 2023.This plan uniformly specifies the test requirements and testing parameters through the work instruction,and evaluates the tensile strength and tensile strain at tensile strength returned by the laboratory through the ratio score.This paper puts forward some technical analysis suggestions for the laboratories with problems and dissatisfaction.
