Foreword

Appendix A and Appendix B of this standard are normative appendices. This standard is proposed and managed by the National Certification and Accreditation Administration. This standard is from the Liaoning Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China, the National Accreditation Committee of China Laboratories, and China Standardization Research. The hospital, the Qingdao Entry-Exit Inspection and Quarantine Bureau of the People's Republic of China, and the Hubei Entry-Exit Inspection and Quarantine Bureau of the People's Republic The main drafters of this standard. Wang Douwen, Song Guilan, Yu Zhenfan, Qi Xiangjun, Chen Changyang. This standard is the first industry standard for entry-exit inspection and quarantine. Laboratory internal quality control method MR statistical merge dynamic tracking monitoring technology

1 Scope

This standard specifies the stability, precision and deviation of the laboratory measurement system using MR statistical combined dynamic tracking monitoring technology. Laboratory internal quality assessment methods for continuous monitoring of performance. This standard applies to laboratory test methods and instrument calibration control; does not apply to different instruments and analytical methods for the same level of characteristics Comparison between multiple measurement systems in which measurements were performed.

3 Terms and definitions

The following terms and definitions apply to this standard. 3.1 The value is agreed upon and is usually obtained by (1) the theoretical value established by the absolute method of scientific principles; (2) based on Designated assignments given by national or international trials; (3) Accurate and reliable analysis by multiple participating laboratories in proficiency testing Method, to provide the inductive value provided by the collaborative value. 3.2 Variable contribution factors that are easily detected and identified. 3.3 The difference between the true value or the ARV and the overall measured mean. 3.4 The centerline and upper and lower limits (CL, UCL/LCL) determined in the controlled graph are used to test whether a set of data is statistically controlled. status. 3.5 The variables produced by the test process of the analytical measurement system are only subject to fluctuations in accidental errors. 3.6 A series of collections of sets of sub-systems involved in determining quantitative values at specific levels of unknown samples. ...
