Like in criteria 3 and 4 of the pragmatic external validity above, he considered that the validation should be based on the links between available information and alternative future developments.
A partial validation should be conducted for a validated method when there is a significant change in the method.
A transfer validation should be conducted when transferring a fully validated method from one laboratory to another which utilizes the same method, same vehicle, same validation range, and same predefined acceptance criteria.
Validity is often treated as a unitary concept, but the process of validation should be an ongoing process of accumulating various kinds of evidence [ 23].
In the near-term explicit model description and routine assumption validation should be mandatory.
Their validation should be based on three approaches: technical and clinical reliability, data protection and cybersecurity.
Guidelines for biomarker study design and statistical evaluation suggest that validation should be conducted using a prospective specimen collection retrospective blinded evaluation design.
The methodology of finite element modeling, simulation, and basic experimental validation should be developed to effectively study the drop-impact effects.
It is important to emphasize that such validation should be based on a multi-level approach similar to the one utilized in validating coupled neutronics/thermal hydraulics codes in international standard problems.
Finally, detailed model validation should be carried out to ensure the model represents the process accurately.
The typical analytical variability as established during method validation should be considered in calculating the release limit. .
