Answer Great Question. The answer is entirely found under the "forced degradation" section of the ICH Stabilty Guidelines (ICH-Q1) and in the analytical valiudation guidelines (ICH-Q2), which can be found at the ICH website (www.ich.org).
When the webpage comes up, click on the large blue colored letter "Q" at the top left of the page, then scroll down the new page to these guidelines.
