Yes, provided the largest window manufactured is tested. All smaller windows having the same system can be approved through comparative analysis and always complying with FBC Sections 2411.3.2.5 and .6. This normally applies to non-impact resistant windows, for impact windows the highest pressures obtained through comparative analysis may not exceed the cycled pressure tested.
