Validation and prevalidation<\/span><\/h4>\n\n\n\n

The test methods are subject to formal validation by the OECD and \/ or by ECVAM (for in vitro<\/em> tests) when it comes to substances, or CEN \/ ISO standardization for media and medical devices.<\/p>\n\n\n\n

This validation ultimately gives a guarantee of quality, enforceability and multilateral recognition by member countries, for example of the OECD<\/a>.<\/p>\n\n\n\n

The principle is that all test laboratories following quality procedures, in particular “good laboratory practice” (GLP) will find the same results.<\/p>\n\n\n\n

The guarantee of quality goes through tests demonstrating repeatability and reproducibility and requires circular tests. These long and costly operations can be done in a pre-validation structure.<\/p>\n\n\n\n

Several definitions of pre-validation exist. For PEPPER, it is a question of ensuring that the methods meet quality criteria, and of constructing the evidence required by the bodies which carry out an internationally recognized validation (OECD, ECVAM, ISO).<\/p>\n\n\n\n
