Do you know the relationship between this one and why it must depend on other one, such as C-14?
If you want to test the reliability of a dating method, naturally you want to test it on objects of a known date. In the case of racemization, that would involve testing it on objects which have been dated historically (for example a book which is known to have been published in a particular year); or against objects which have been dated by dendrochronology; or against objects which have been carbon-dated. For the tests to be meaningful, the dating methods you're testing it against must be reliable.
