PDA Technical Glossary
PDA Technical Reports are highly valued membership benefits because they offer expert guidance and opinions on important scientific and regulatory topics and are used as essential references by industry and regulatory authorities around the world. These reports include terms which explain the material and enhance the reader’s understanding.
The database presented here includes the glossary terms from all current technical reports. The database is searchable by keyword, topic, or by technical report. Each definition provided includes a link to the source technical report within the PDA Technical Report Portal.

Validation
A documented program that provides a high level of scientific assurance that a manufacturing process will reliably produce acceptable product. The proof of validation is obtained through rational experimental design and the evaluation of data, preferably beginning from the process development phase and continuing through the commercial production phase. (TR01)
A documented program that provides a high degree of assurance that a specific process, method, or system will consistently produce a result meeting predetermined acceptance criteria. (TR26) (TR57) (TR70) (TR74)
Documented testing, performed under highly controlled conditions, which demonstrates that a process consistently produces a result that meets predetermined acceptance a result that meets predetermined acceptance criteria. Used to test processes, methods, and systems for which conditions can be controlled in the real world (i.e., after completion of testing, when the process is in use). Transportation processes can be qualified but not validated; in the real world, it is not possible to exert control over all parameters that could affect the transportation process (e.g., weather, customs, traffic delays, mechanical failures, etc.). (TR58)
A documented program that provides a high degree of assurance that a specific process, method, or system will consistently produce a result meeting predetermined acceptance criteria. (Note: Validation is a lifecycle program which may include development and qualification activities for one or more elements/systems that form a process.) (TR54-5)
A documented program that provides a high degree of assurance that a specific process, method, or system will consistently produce a result meeting pre-determined acceptance criteria (17). (TR60-3)
