Validation of testing methods, verification of testing methodsAbstract
The main objective of this article is to clearly and simply establish the difference between validation and verification of a testing method. A brief discussion is presented on the selection and validation of testing methods as established by the ISO/IEC 17025:2005 standard. The process of method standardization is described, along with a concise overview of validation parameters as characteristic indicators of method performance, providing some brief guidelines for their application. The article also presents selected contents of standardized methods, highlighting the specifications derived from validation data. Finally, the verification process is described, emphasizing its distinction from validation, with a focus on confirming the method's specifications.
