TSAR : Tracking System for Alternative test methods Review, Validation and Approval in the Context of EU Regulations on Chemicals

Review and Validation
Validation
the scientific process by which the reliability and relevance of a procedure are established for a specific purpose.
It generally involves a formal interlaboratory study with the testing of coded chemicals, but also other procedures as a retrospective validation based on the assessment of existing data are possible and often used.
