AAMA Product Testing
All windows and sliding glass doors must go through basic testing that results in an AAMA classification; commonly called NAFS (North American Fenestration Standard). Local building codes reference this standard accompanied by an AAMA class (R, LC, CW or AW) and a design pressure (50,55,60 etc.). The class and design pressure dictate the rating of the window according to what part of the country it goes into. Testing is meant to simulate the stresses a window or sliding glass door may go through during typical use.
