Introduction

Chemical analysis involves many industries and fields such as chemical industry, petroleum, geology, environment, food and medicine, and the validity of laboratory test results is monitored especially important. With the wide application of the international standard ISO /IEC 17025 and the continuous enhancement of laboratory quality awareness, laboratory managers have More and more attention has been paid to the monitoring of the validity of the test results, and the monitoring of the validity of the test results has become an important part of laboratory management. Although ISO /IEC 17025 gives general requirements for laboratories to ensure the validity of results, and applies to all testing laboratories carrying out test results with The organization and management of effectiveness monitoring, however, due to the uneven level of laboratory capacity, many laboratories are carrying out results effectiveness monitoring and management. There is still a lot of confusion. According to the technical characteristics of chemical analysis laboratories, this document clarifies the general principles of monitoring and management of the effectiveness of results, and guides the risk-based The basic method of analyzing and evaluating results is used for monitoring and planning, and the selection and evaluation of internal monitoring methods, external monitoring methods and their results are given. The specific guidance for application is aimed at improving the quality of laboratory test results and improving the validity and reliability of laboratory test results. Guidelines for Monitoring the Validity of Chemical Analysis Laboratory Results

1 Scope
