for reliable results
Validation of
established requirements, and we can confirm that the procedure used in the laboratory meets these requirements in terms of routine measurements. Validation is the
key to reliable results (Fig. 7.1).
Validation (from the Latin validus; meaning in English strong, powerful, worthy): documenting that a process or system meets its predetermined specifications and quality attributes.
Validation versus verification
The terms verification and validation have been described in the ISO/IEC
17025:2017, Clause 7.2. It is highlighted that validation includes specification of
the requirements, determination of the characteristics of the methods, a check that
the requirements can be fulfilled by using the method, and a statement on the validity.
Interestingly, in the current edition of the International Vocabulary of Metrology—Basic and General Concepts and Associated Terms, ISO/IEC Guide 99:2012,
there are two definitions referring to the terms ‘verification’ and ‘validation.’
Verification: provision of objective evidence that a given item fulfils specified
requirements
