DB51/T 2156-2016 Guidelines for evaluating and utilizing measurement uncertainty in chemical analysis laboratory
Basic Information
Scope
This standard proposes guidelines for the evaluation of measurement uncertainties in the field of chemical analysis in chemical analysis laboratories and their application in laboratory quality management. Note: The chemical analysis referred to in this standard specifically refers to the use of standard substances to assign values to target components through comparative detection methods, and the use of titration analysis methods to obtain the content and concentration of target components. This standard applies to the evaluation of measurement uncertainties in chemical analysis in chemical analysis laboratories and their application in laboratory quality management, and meets the requirements of GB/T 27025 "General Requirements for the Competence of Testing and Calibration Laboratories", the "Evaluation Criteria for the Qualification of Inspection and Testing Institutions" of the National Certification and Accreditation Administration, and the requirements for the evaluation of measurement uncertainties in chemical analysis in chemical analysis laboratories. The content of this standard does not apply to other analysis fields.
