2009 IBC, 2408.3 Gymnasiums. "Glazing in multipurpose gymnasiums, and similar athletic facilities subject to human impact loads shall comply with Category II of CPSC 16 CFR 1201 or Class A of ASNI Z97.1 listed in Chapter 35." Occupant of commercial gymnastics business wants to put observation windows in the wall between the gymnasium area and the area where parents can observe their children. Window company wants to know what the heck CPSC 16 CFR 1201 and/or Class A of ANSI Z97.1 requirements are? What does the window company have to provide to prove their window meets these requirements? (ps, I'm an old plexi-glass guy myself, but that probably don't meet code). Help please. Uncle Bob
